Principles

The BAX-LOK twin ferrule fitting consists of four precision engineered parts designed to provide secure leak- proof joints capable of satisfying high pressure, vacuum and vibration applications.

Fittings are supplied complete and ready for use. The front ferrule swages onto the tube as it moves down the cone of the body creating a pressure/vacuum-tight seal on both tube and body by the interface pressure and surface finish of mating components. The back ferrule then deforms inwards in the cone of the front ferrule, forming into the tube and creating a strong mechanical hold on the tube.

The internal diameter of the body and nut are closely controlled diameters which constrain the tube within a close tolerance of its axis ensuring accurate alignment within the assembled fittings

Quality Assurance
Product Specification
Application

Manufacturing and ordering processes are tightly controlled by a quality assurance program as per BS 4368 Part IV by carrying out inspection/testing activities at 3 stages as per QAP

The BAX-LOK fittings are widely used in Onshore, Offshore, Chemical, Petrochemical and other Process industries. The fittings comply with ASTM / BS / IS specifications
The BAX-LOK fitting has been specifically designed for use on instrumentation, process and control systems, together with equipment employed in Chemical, Chromatography, Petroleum, Power Generation and Pulp & Paper plants.

Sealing

BAX-LOK tube fittings do not twist the tube during installation. The BAX-LOK fitting design ensures that all make and remake loading is transmitted axially to the tube.  Fitting make-up is eased due to a silver plating of the tube nut threads, which acts as an effective lubricant and prevents galling.

In make-up, there is no undue force in an outward direction to distort the fitting body or ferrules to cause interference between the ferrules and the nut. This assures that the nut will back off for disassembly and permits a greater number of end remarks.
Positive, reliable connections with BAX-LOK fittings have been qualified with exhaustive tests and over years of experience in the manufacture of quality tube fittings. Specific product features such as burnished cones for superior sealing and exacting manufacturing tolerances for consistent product quality, all contribute to the effective sealing of the fittings. In tests, after repeated remakes BAX-LOK fittings effected a Helium seal at over 200 bar. Vibration and impulse tests in the multi-million cycle range prove outstanding sealing capability and fatigue resistance.


HOW TO IDENTIFY METRIC FITTINGS

Metric tube fittings are identified by a stepped shoulder on both the body and the threaded end of the nut as illustrated.

Selection

The BAX-LOK twin ferrule tube fitting is precision engineered to exacting standards. Careful selection of high quality tubing together with the appropriate BAX-LOK fitting will ensure the installation of safe, leak free systems. The following tables are intended as a guide to tube ordering. The tube sizes listed are regularly tested to bursting pressure in both maximum and minimum wall thickness using correctly assembled BAX-LOK tube fittings, with no sign of leakage or failure at the connections.  For use with tubes of wall thickness other than those listed, recommendations regarding working pressures for BAX-LOK fittings can be obtained from our Technical Dept.

Tube should be fully annealed high quality stainless steel tubing to ASTM A-269 or equivalent. The preferred hardness is Rb 80 or less, if harder tube is used Rb 90 is the maximum allowed under ASTM A-269.

BSP threads

BSPP and BSP Taper threads have a thread angle of 55o.
The spot face surface must be square to the pitch diameter and free from longitudinal and spiral tool marks.

BSPP – British Standard Pipe Parallel threads are used in tubes and fittings where pressure-tight joints are not made on the thread, i.e. a peripheral seal is used.

BSP Taper – British Standard Pipe Taper threads are used in tubes and fittings where pressure-tight joints are made on the threads.

Thread Standards:
BSPP thread to: ISO 228-1, BS2779, DIN 3852 part 2,
BSP Taper thread to: ISO 7/1, BS21


 

 

 

 

 

Sealing


Interference sealing of taper threads

Pressure-tight joints of screwed connections with taper threads are achieved by the application of a sealant to the surface of the external male thread.
A minimum of five layers of PTFE tape should be wound around the external taper thread prior to the assembly.
Starting with the first thread, wrap the tape in the direction of the thread spiral.
Ensure that the PTFE tape does not overhang the first thread. PTFE tape should be to the BS4375 specification

Sealing compounds and liquid sealants.

Apart from polymer joint compounds and air-drying liquid sealants, the most common thread seal is an anaerobic synthetic resin, which cures in the absence of air.

Connections are normally ready for operation following one hour curing time, complete curing may take up to 24 hours.

Peripheral sealing of parallel threads

Pressure-tight joints of screwed connections with parallel threads are achieved by placing a seal between the two-machined faces.

Flat seal

Washers and rings are manufactured in many different materials including fully annealed 316 stainless steel, copper, aluminum, fiber, and plastics.

The tightening torque at assembly will vary according to the tensile strength of the fitting material, and the elasticity of the peripheral seal. The torque should be carefully selected to avoid compressing soft seals to the point of extrusion.

Bonded seals

Elastomer sealing rings bonded into metal washers. Bonded seals are reusable, and cater for a variation in the quality of the machined surfaces.

Installation

Interference sealing of taper threads

BAX-LOK tube fittings are supplied completely assembled.

Normal uses

1-Ensure that the end of the tube is cut square and any burrs removed without causing undue chamfering of the tube end.
2-Insert the tube into the BAX –LOK fitting ensuring that the tube is firmly butted home into the body of the fitting and the nut is finger tight.
3-With the body firmly held, mark the nut in the finger tightened position, and rotate the nut one and a quarter turns from the marked position (fig.1). The correctly made connection is then completed.
4-For sizes up to 3/16” tube fittings, only three quarters of a turn from finger tight is necessary.

High pressure applications, high safety factor systems

To allow for possible tolerance variations in tube diameters when the application demands the maximum pressure sealing capabilities of the fitting, it is recommended that the nut is tightened until the tube cannot be rotated by hand. From this point the nut should be tightened one and a quarter turns.

Re-tightening and dis-assembly
With BAX -LOK tube fittings the connection can be disconnected and retightened many times and the same reliable, safe, leak proof connection obtained.

Pre Assembly

For applications where lack of space precludes normal assembly a set of hardened pre-assembly tools is available to enable the nut and ferrules to be pre-assembled onto the tube. With the assembly tool secured in a vice, insert the tube and assemble (fig. 4) as per installation instructions.

Break the pre-assembled joint and insert this assembly into the fitting body (fig 5). Re-assemble as stated in the re-tightening instructions

JUAL HY-LOK NEEDLE VALVES

hylok-needle-valves-2
 
 

Hy-Lok needle valves offer secure, leak-free connections and provide the lowest overall cost of any instrument needle valve used in the market today.

Needle valves within a block and bleed function help achieve positive isolation within maintenance operations of a live process plant. These work well in non-critical processes like with non-hazardous fluids or a low pressure system.
The small port and needle-shaped, threaded plunger allows for precise flow regulation in low flow applications. Not only for maintenance, needle valves also work well in flow-metering operations, and are especially good at maintaining a calibrated and constant low flow rate.
Rugged and compactly designed, Hy-Lok offers a wide range of sizes (1/8″ to 1″), and stem tips (v-stem, regulating, and soft seat) that work well for a variety of applications, including hydraulic and pneumatic systems. Of 316 stainless steel as standard, and some as alloy 400, Hy-Lok needle valves are meticulously designed for the flow, temperature and system required.

Two ferrule tube fittings are designed and manufactured to meet the rigorous specifications required of industrial applications. Hy-Lok tube fittings are commonly used throughout the oil and gas, pulp & paper, petro-chemical/chemical processing, research laboratories, aerospace and defense, chemical processing, power generation, cryogenic and semiconductor, shipbuilding and heavy industrial industries.
Available in numerous configurations and sizes, our tube fittings are made up of four parts consisting of a body, front ferrule, back ferrule, and nut. Outstanding leak-tight connections are consistent as the two-ferrule design compensates for any tolerances in tube outer diameter, wall, thickness, and material hardness.
Hy-Lok tube fittings feature a low torque assembly and positive leak free seal for easy assembly and reassembly. During installation the mechanical properties of the tubing are maintained because the back ferrule moves in a controlled manner that does not stress or reduce the inner diameter of the tubing. Since the front ferrule does not force the body to expand the nut can be backed off easily for disassembly and remakes.
Constructed of standard materials including 316 stainless steel, brass, and Monel, other materials such as duplex stainless steel, titanium, and carbon steel are available upon request. Heat code traceability for 316 stainless steel and Alloy 400 assures the ratings and quality of each fitting and accounts for code requirements.
Fitting size range from 1/16″ thru 2″ (2 mm thru 38 mm O.D.tubing) with numerous choices in end connections and patterns. They are rated to the maximum working pressure of the recommended tubing.  Hydraulic swaging tools (EZY-MAT) are provided for easy installation.
Hy-Lok tube fittings are manufactured to Hy-Lok’s stringent quality control program and standards which assure the highest quality available in the industry. We are a global industry leading provider of fitting solutions and have obtained ASME Quality and ISO 9001:2008 Certifications.
To fulfill the need for leak-free gas and fluid containment, our tube fittings are the ideal solution.

Hoke Gyrolok Compression Fittings

HOKE Gyrolok Compression Fittings or tube fittings have been carefully designed and manufactured to provide outstanding leak-tight integrity in a wide range of applications. The fittings provide safe, reliable performance from cryogenic temperatures to high temperature bake out levels, depending on material.
A key feature with Gyrolok tube fittings is that you can remake the fitting. With traditional compression fittings when you inset the tube into the fitting it bottoms out, forming a right angle [between the tube and the fitting] which leaves no additional space for movement as you tighten the fitting down. Since you are pushing the tube forward as you tighten it, this tends to lead to the tube galling or sticking (commonly known as a “tube sticking”). This can results in longer down times due to the need to cut out the valve or fitting that the tube is stuck in and replacing with a new valve or fittings.
Gyrolok tube fittings have a slight taper (sizing angle) at the base of the fitting allowing the tube to stop before bottoming out, yet still allows the tube room to move forward as the nut is tightened, thereby reducing the tendency for it to stick or gall. This key feature of Gyrolok tube fittings allows you to repeatedly undo and redo the connection to perform any needed maintenance, resulting in less down time and the need for new materials.
Traditional tube vs gyrolok tube
Important design features of Gyrolok compression fittings vs. other compression fittings.
Controlled Ferrule Drive:
Helps prevent overstressing (by reducing O.D. cutting) of tubing or excessively reducing tubing inside diameter.
Front ferrule shoulder:
Front ferrule shoulder prevents body expansion and nut jamming, caused by over-tightening.
Butt Seal:
The Butt Seal provides a secondary seal and eliminates dead space where contaminants could be trapped.
1 ¼ Turns to Lock…Always:
All sizes, all materials, all pressure ratings are 1 ¼ turns to lock the fitting in place.
Guaranteed Interchangeability:
Gyrlok Tube Fittings have guaranteed interchangeability with other tube fittings.
