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.

PE4710 and PE100 are both grades of high-density polyethylene (HDPE), but PE4710 is derived from PE100 and offers higher performance, particularlyin pressure applications. PE100 has similar or lower physical property requirements than PE4710, while PE4710 has stricter design factors andadditional performance requirements.
Key Differences:
Performance Requirements: PE4710 has higher performance requirementsincluding better resistance to slow crack growth (SCG) and rapid crackpropagation (RCP) compared to PE100.
Packing: Jumbo bags
