Since there are many kinds of materials and many materials are not commonly used, today we will only talk about several common metal materials. Carbon steel: refers to iron carbon alloy with carbon content of 0.0218%~2.11%. Also called carbon steel. Generally, it also contains a small amount of silicon, manganese, sulfur and phosphorus. Generally, higher carbon content in carbon steel means higher hardness, higher strength, but lower plasticity. In fact, our domestic pipe fittings are generally called carbon steel, such as Q235 20 # and even Q355. This is actually a simple and convenient name, so it is not correct strictly.

Pipe fittings are the general name of the parts that play the role of connecting, controlling, changing direction, diverting, sealing, supporting, etc. in the pipe system. Today we will discuss why there are so many materials for pipe fittings?

Generally speaking, pipe fittings are made of the following materials without very special requirements:

1. Cast steel pipe fittings

2. Cast iron pipe fittings

3. Stainless steel pipe fittings

4. Plastic pipe fittings

5. PVC pipe fittings

6 Rubber pipe fittings

7. Graphite pipe fittings

8. Forged steel pipe fittings

9. PPR pipe fittings

10. Alloy pipe fittings

11. Pe pipe fittings
