Material of Casing Pipe
Casing pipe materials vary, and the specific choice depends on the application scenario and requirements. The following are some common casing materials and their characteristics:
Metal casing
Including carbon steel, stainless steel (such as 304, 316 stainless steel), etc. Carbon steel casing pipe is affordable and widely used, suitable for general water pipes and drainage pipes. Stainless steel casing has good corrosion resistance and is suitable for chemical pipelines and occasions where corrosion protection is required.
Carbon steel is a metal material with high strength, good wear resistance, easy processing and formation, and good weldability. Seamless casing is made of seamless steel pipe as raw material; seamless steel pipe refers to carbon steel made of four methods: hot rolling, cold rolling, hot drawing, and cold drawing. The pipe body itself has no welds and can be used in drilling projects such as oil and gas wells and water wells, as well as the protection of oil and natural gas pipelines.
2. Stainless steel casing pipe
Stainless steel is a metal material with the characteristics of corrosion resistance, oxidation resistance, and high strength. It is often used to make pipelines, containers, etc. Stainless steel casing has the characteristics of corrosion resistance, high temperature resistance, and high strength, and is widely used in food, pharmaceutical, chemical, petrochemical and other fields.
3. Titanium alloy casing pipe
Titanium alloy is a high-strength, low-density, corrosion-resistant metal material, which is widely used in aviation, aerospace, medical, chemical and other fields. Titanium alloy casing has the characteristics of high temperature resistance, corrosion resistance, and high strength, and is widely used in aerospace, nuclear power, marine engineering and other fields.
3. Aluminum alloy casing pipe
Aluminum alloy is a lightweight and high-strength metal material, which is mainly used in aviation, vehicles, construction and other fields. Aluminum alloy casing has the characteristics of light weight, high strength, and good thermal conductivity, and is widely used in electronics, communications, aviation and other fields.
Non-metallic casing pipe
Casings made of plastic materials such as PVC, PE, PP, and ABS are suitable for the protection of wires and cables. Casings made of these materials have good insulation and durability, and are widely used in electrical installation and power engineering. Plastic is a widely used material with the characteristics of easy carrying, low cost, and not easy to rust. Plastic casing is suitable for home, daily necessities, electronic accessories and other fields.
Fireproof casing pipe
It is made of high-purity alkali-free glass fiber and coated with organic silicone on the outer wall. It can be used for a long time in the temperature range of -65°C to 260°C, and it remains soft and elastic. It is suitable for occasions that require fire protection.
Special material casing pipe
For example, copper casing is made of electrolytic copper as raw material, adding a variety of trace metal elements, and processed by high-temperature sintering and gas pressure centrifugal casting. It has high hardness, wear resistance and good corrosion resistance, and is suitable for wear-resistant parts working under high load and high sliding speed.
