Pipe fittings are the general names of parts and components that play the role of connection, control, direction change, diversion, sealing and support in the pipeline system. Steel fittings are pressure fittings. According to the different processing technology, it is divided into four categories, namely, butt welding pipe fittings (divided into weld and no weld), socket welding and threaded pipe fittings, flange pipe fittings. According to the application: 1. pipe fittings for connecting pipes are: flanges, live joints, pipe hoops, clamps, clamps, throat hoops, etc. 2. changing the direction of the pipe: bends, bends. 3. pipe fittings changing pipe diameter: variable diameter (different diameter pipe), different diameter elbow, branch pipe table, reinforcing pipe. 4. pipe fittings with additional piping branches: three links, four links. 5. pipe fittings for pipe sealing: gasket, raw material belt, thread, flange blind plate, pipe plug, blind plate, head, welding plug. 6. pipe fittings for pipe fixing: clasp, hook, ring, bracket, bracket, pipe clamp, etc. According to the connection :1, welded pipe fittings 2, threaded pipe fittings 3, clamping pipe fittings 4, clamping pipe fittings 5, socket pipe fittings 6, rubber ring connection pipe fittings According to the material divided into 1, cast steel pipe fittings 2, forged steel pipe fittings 3, alloy pipe fittings 4, stainless steel pipe fittings. Pipe fittings are widely used in municipal, petrochemical, west-to-east gas transmission, ships and nuclear power.

Fasteners are the general term of the class of mechanical parts used in fastening two or more parts (or components) into a whole. It is widely used in energy, electronics, electrical appliances, machinery, chemical, metallurgy, mold, hydraulic and other industries, at the same time, in various kinds of machinery, equipment, vehicles, ships, railway, bridge, construction, structure, tools, instruments, chemical, instruments and supplies, you can see all kinds of fasteners, is the most widely used mechanical foundation parts. It is characterized by a wide variety of variety specifications, different performance uses, and a very high degree of standardization, series, and generalization. Therefore, a class of fasteners that already have national standards is called standard fasteners, or simply standard ones.
Description of SBG800 HDPE/PP Double Wall Corrugated Pipe Extrusion Line: Features of pipe: Diameter scope: (ID) 500mm-800mm Double wall corrugated pipe line: In order to meet the demand of plastic market, HUASU Company designed and developed this HDPE Double Wall Corrugated Pipe Extrusion Line SBG800 by absorbing advanced technology from foreign countries plastic machinery industry. This HDPE Double Wall Corrugated Pipe Extrusion Line is the latest study achievement in the plastic extruding area. The whole extrusion line is suitable for the high speed extrusion of HDPE, LDPE, and PP material. The complete line adopts directly extrusion (two extruders co-extruding) and forming technology, human-machine interface control system. It makes high automation degree, reliable quality and stable production become true. And this pipe production line wins our home and abroad customers good reputation.
HDPE Double wall corrugated pipe extrusion line Main features -- It adopts efficient screw and notched barrel, the inner and outer walls are separately extruded by two extruders for using different materials and ensuring efficient extruding. -- A high speed of production can be ensured by the corrugated forming system and forced cooling system combined with water and air cooling during constant production. The advanced programmable lubricating system decreases abrasion of mould blocks to a minimum while lengthening their lifespan and ensuring running precision and stable quality. -- The advanced inline double wall belling function can reach or exceed the requirement of the state standard, completely solving disadvantages of the pipe's creep and leakage of sealing in sockets. -- Co-extrusion die with special structure makes the inner and outer walls even and stepless adjustable, and forming stable. -- The cast mould blocks are made from special alloy for high precision and strength and excellent radiation effect. -- A professional PCC (B&R, Austria) control system is adopted with 15" touched colour screen for high automation, reliable running and easy operation. -- It adopts a quick changing system for the mould blocks. -- The optimum design of crest provides a perfect combination of higher ring stiffness and lower unit weight. -- Long-distance communicative function can realize tele-diagnosis and maintenance. -- The key and new product of the State. -- It is certified for CE quality system by China Quality Certification Centre.
