Reducing elbow: When making a 90-degree turn, the diameter of the pipeline changes, including hot push elbow, stamping elbow and welding elbow.
Branch pipe platform: used to strengthen pipe fittings for branch pipe connection, instead of using reducing tee, reinforcing plate, reinforcing pipe section and other connection forms.
Tee: Tee is a kind of pipe connector, also called pipe fitting tee or tee pipe fitting and tee joint, which is used in the main pipeline where the branch pipe is to be made.
Four-way: used to connect four pipes with the same diameter and the same vertical direction, mainly used for shunting or changing direction.
Gasket: a material placed between two planes to strengthen the seal, and a sealing element arranged between tight covers to prevent fluid leakage.
Raw material belt: an auxiliary product commonly used in plumbing installation, which is used at the joint of pipe fittings to enhance the tightness of pipe fittings connection.
Linen and linen: an auxiliary product commonly used in pipeline installation. Used for winding the threads of pipe fittings to play a sealing role and prevent water leakage.
Flange blind plate: also known as blind plate, the real name is blind plate, which is a connection form of flange, actually a flange with no hole in the middle.
Pipe plug: refers to the externally threaded pipe fitting used to plug the internal thread at the end of the pipeline, including square pipe plugs and hexagonal pipe plugs.
Head: a component of a container, which is an element used to seal the end of the container and isolate the internal and external media. It is also called end cover.
Welding plug: used to protect some parts of weldment that need protection or are easy to be injured and deformed during welding.
Pipe clamp: pipe fittings used to fix pipes, often used in plumbing installation, used to fix pipes.
Valve: the control part in the fluid conveying system, which has the functions of cutting off, regulating, shunting, stabilizing pressure, shunting or overflow pressure relief.
Compensator: It consists of bellows, end pipe, bracket, flange, conduit and other accessories, and belongs to compensation element.
Decontamination device: prevent impurities in pipeline medium from entering conveying equipment or precision parts, causing production failure or affecting product quality.
Reinforcing tube: Strengthening means increasing strength. By increasing the stress area, the strength of this area is improved, which is basically a forged pipe.
Clasp ring: It is the main retainer of removable denture, made of metal, which mainly plays the role of retention, stability and support.
Towing hook: refers to the hook on the tugboat used to hook the towing cable and facilitate its release. It can be divided into spring towing hook, hydraulic towing hook and remote control towing hook.
Lifting ring: it is a kind of industrial sling and a device used to lift heavy objects in lifting machinery. Common rings are round rings and pear rings.
Bracket: the truss supporting the middle roof truss is called bracket, which generally adopts parallel chord truss, and its web bar adopts herringbone system with vertical bar.
PART2 is divided by connection mode.
Welded pipe fittings: pipe fittings connected with pipelines by welding, including elbows, flanges, tees, reducers, heads, etc. Threaded pipe fitting: it is a kind of threaded pipe fitting, which is commonly used in water pipes, gas pipes, small-diameter water pipes, compressed air pipes and low-pressure steam pipes.
Casing pipe fitting: it is a new type of quick pipe fitting with good sealing performance and can be reused. Suitable for pipeline systems of oil, gas and general corrosive media.
Clamp parts: used to fasten the clamp connection between quick connectors, including clamps, quick connectors, silicone sealing washers, chuck blind plates, etc.
Pipe fitting: a kind of high-pressure pipeline connecting pipe fitting which is forged by round steel or ingot and machined by lathe.
Curved-elastic double-fusion pipe fittings: The pipe fittings with the same size as the pipes to be connected are connected by hot-melt butt welding.
Bonded pipe fittings: pipe fittings connected with solvent-based adhesives, such as PVC plastic pipes.
Rubber ring connecting pipe fitting: it consists of pipe fitting body, sealing end cover and sealing rubber ring.
Part 3 by material
Steel castings and fittings: Steel castings are designed to be thick and heavy, with poor weldability and high carbon content, and the weld needs on-site heat treatment.
Rubber pipe fittings: mainly used for conveying and inhaling liquids and gases in industry, mining and civil use, including rubber hoses, rubber gaskets and rubber grouting pipes.
Cast iron pipe fittings: pipes made of cast iron, including water supply cast iron pipes, sand centrifugal cast iron straight pipes and drainage cast iron pipes. Stainless steel pipe fittings: including stainless steel elbow, stainless steel tee, stainless steel cross, stainless steel reducer, stainless steel pipe cap, etc.
Plastic pipe fittings: made of synthetic resin, stabilizer, lubricant and plasticizer by extrusion. Mainly used as water supply system pipeline, drainage, exhaust and sewage sanitary pipeline, rainwater pipeline, wire threading pipe, etc.
Pvc pipe fittings: PVC resin, stabilizer, lubricant, etc. It is mixed and extruded by hot pressing method, which can be divided into PVC-U tube, PVC-M tube and PVC-O tube.
Graphite pipe fitting: refers to the combination of impermeable graphite pipe and pipe fitting, which is mainly used to transport corrosive media without metal ion pollution and has good thermal conductivity.
