What to do when using seamless steel pipes?

The application of seamless steel pipes mainly reflects three major fields. One is the construction field, which can be used in the construction of high-rise buildings, bridges and other infrastructure. The second is the processing field, which can be used in mechanical processing, bearing sleeves, etc. The third is the electrical field, including pipelines for gas transmission, fluid pipelines for water power generation, etc.

So what to do when using seamless steel pipes?

1.Cutting process

Seamless steel pipes can be cut when in use. The purpose of cutting is to meet the usage requirements. Therefore, the length and other dimensions must be measured before cutting to meet the usage requirements. When cutting, you must choose appropriate tools. Generally, metal saws, toothless saws and other tools can be used for cutting. At the same time, both ends of the fracture must be protected, that is, use fireproof and heat-resistant baffles to prevent splashing sparks. , hot iron beans, etc.

2. Polishing treatment

The cut pipe opening needs to be polished, and an angle grinder can be used for grinding. The purpose is to prevent the plastic layer from melting or even burning during the welding operation, causing pipe damage.

3. Plastic coating treatment

After polishing, oxygen and C2H2 are used to heat the pipe mouth outside the pipe until the internal plastic layer melts. Then the technical worker will evenly apply the prepared plastic powder to the pipe mouth. Pay attention to the application and make sure it is in place. The plastic coating on the flange should be applied above the water stop line. The heating temperature should be strictly controlled in this process. If the temperature is too high, bubbles will be generated during the plastic coating process; if the temperature is too low, the plastic powder will not melt completely during the plastic coating process.
