Straight seam steel pipe production temperature:In the process of producing straight seam steel pipes, the temperature must be strictly controlled to ensure the reliability of welding. If the temperature is too low, the welding position may not reach the temperature required for welding. When most o

Plastic-coated steel pipes are composed of a core tube rent reduction layer, fastening steel belt, air layer, insulation layer, reflective layer, sliding bracket, outer protective steel pipe, sprayed polyurethane, and surrounding entangled fiberglass. They are characterized by high strength, not eas

First, the concept of stainless steel pipesIt is a hollow long steel strip, which is widely used as a pipeline for conveying fluids, such as oil, natural gas, water, coal gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely use

High-pressure seamless steel pipes are high-pressure boiler steel pipes. Because high-pressure seamless steel pipes are usually used in pipes of high-temperature and high-pressure boilers, they are also called boiler steel pipes. Although the above two pipes are called differently, they are the same
