The difference between double and single fittings

double ferrule tube fittings and single tubing fittings are used on the card sleeve. Dual card sets using special alloy, large deformation, but also to ensure its rigor and sealing, its strength is better than other materials.
General tube connection can use double or single fittings, dual card ring card sets can be repeated several times and can guarantee tightness disassembly. Single card sets of pipe fittings and ordinary and tube connections, as a head no need thread connecting with ordinary tube, threaded to connect to the card casing. For large double ferrule can ensure the strength, the small card sets to meet deformation requirements of use. Fittings mainly by the joint body with 24 degrees conical hole with a sharp inner edge of the sleeve 2 and the pinch effect from the compression nut 3 III some components. 3:00 tighten the nut, sleeve 2 is pushed 24 degrees tapered bore and consequent deformation, so that the body of tapered ferrule and fittings constitute a spherical touch seal. Inner edge card sets embedded steel tube 4, the outer wall of the pressure out of a ring groove, then play a reliable sealing effect. Pipe stress relief annealing best selection of 20 # fine extubation, it is a good edge embedded in the outer appearance of pipe fittings, play reliable sealing effect.

pipe fittings design requirements

high pressure pipe fittings installation with the low-pressure pipe installation requirements similar, but more demanding, more stringent provisions, therefore, in addition to the requirements, the low-pressure pipe installation requirements, the following requirements should still perform.
When the high-pressure pipeline installation, you should use the official fixed pipe rack, pipe rack and high-pressure pipes, pipe fittings contact design requirements should install a protective sleeve. Installation should expose the high-pressure pipe flange end thread chamfer. When installing the gasket, do not use a wire dipping advance shall nozzle and pad coated with butter, soft metal high-pressure washer should be accurately placed in a sealed housing. The flange bolts should be symmetrical and evenly tightened, not over after the bolt tightening, two concentric flange should remain parallel, exposed on the outside of the nut should be 2 to 3 buckle, at least not less than 2 buttons, and various bolts exposed length consistent. During the installation process, not use strong pull, strong push, strong twist or modify gasket thickness ways to compensate for manufacture or installation error. Pipeline installation work as impossible to continuously conducted and completed, should be promptly closed the open nozzle. Parts meter sampling site should also be installed on the pipe and the pipe.

steel tubing pipe specifications

stainless steel tubing fittings suitable for thin-walled tubular member and a lower pressure of the occasion.
Flared type tubing fittings for medium: oil, water, gas and other non-corrosive or corrosive media fittings, equipped with flexible steel tubing pipe specifications, pipe welding after having connected securely, sealing performance good features, which are widely used in oil refining, chemicals, light industry, textile, defense, metallurgy, aviation, shipbuilding and other systems; also suitable for all kinds of mechanical engineering, machine tools and equipment such as hydraulic transmission lines.
Flared type tube fittings used with check valve quick couplings: in supply / return oil and stress testing interface, pump oil interface, with self-proclaimed role when not connected tubing. Back to oil and hydraulic fluid interface with flared fittings. Hydraulic component assembly and rubber hose (not shown): components and fittings needed to connect the circuit is a separate component of the test bed, hydraulic components for the plate valve, separate board installed in a standard transition, transition plate surrounded by a corresponding number of external components equipped port fittings, the back transition board has "T" shaped pegs for mounted hydraulic components.

High pressure stainless steel tubing fittings

High pressure stainless steel tubing fittings are the most widely used chromium - nickel stainless steel, with outstanding corrosion resistance, heat resistance, low temperature strength and mechanical properties. Corrosion in the atmosphere, and if it is heavily polluted industrial atmosphere or region, demand for timely cleaning to prevent corrosion. Suitable for use in food processing, storage and transport. Outstanding processing capabilities and weldability. Plate heat exchanger, bellows, household goods, building materials, chemical, food industries.
Operational capacity of its high pressure pipe fittings where the stress related to the situation. Accounting and field operations for pipe stress measurement found elbow arc particularly sensitive point in the external load. To get rid of internal pressure and external load weight, etc. mainly in the starting process piping thermal expansion of metal pipes, tubing hanger sensation and abnormal operations and other additional external load caused. When the elbow is a cross-sectional arc butt weld, these changes will form a crater in the external load stress messy situation, severe weakening the weld strength and decrease operational capability elbow, elbow shorten life. To this end, from the depicted think the interface into the straight section butt welded elbow, that is portrayed with a straight segment elbow, it is conducive to weld butt weld quality progress, improvement elbow life.

Tube Fittings have a solid connection

Tube fittings suppliers said that Tube Fittings have a solid connection, high voltage capability, temperature, sealing, and repetition is good, easy installation and maintenance, safety and reliability.
Works Tube Fittings is the steel insert card kit, use card sets nut, inconsistent card sets, cut the tubing pipe and seal. When it is connected with the pipe without welding, it is conducive to fire, explosion, and high-altitude operations, and to eliminate the evils of careless welding. So it is oil refining, chemical, oil, gas, food, pharmaceutical, instrumentation, and other pipeline systems controlled device in a more advanced connection. It applies to pipe oil, gas, water and other connections.
Card sets of pipe fittings is composed of three parts: the connector body, sleeve, nut. When the card is inserted into the sleeve and the sleeve nut on the pipe joint body, when tightening the nut, the front end of the outer sleeve and the connector body tapered fit, uniformly bite into the inner edge of seamless steel tubes, to form an effective seal.
