High pressure pipe 3
The 20G high pressure boiler tube guarantees a material wall thickness ranging from 2.0 to 2.0. Shaped seamless steel pipe is a general term for seamless steel pipes with a cross-sectional shape other than round pipes. According to the different shapes and sizes of steel tube sections, it can be divided into special-shaped seamless steel pipes of the same thickness (code D), special-shaped seamless steel pipes of different thicknesses (code BD), and variable-diameter seamless steel pipes (code BJ) . Shaped seamless steel pipes have long been used in various structural parts, tools and mechanical parts. Compared with round pipes, special-shaped pipes often have larger moments of inertia and section modulus, and have greater ability to resist bending and torsion. The wall thickness varies from 20 to 70 mm. Cold-drawn (cold-rolled) pipe outside diameter 10 ~ 108mm Specifications and appearance quality: GB5310-08 "Seamless Steel Tube for High Pressure Boiler" The outer diameter of hot-rolled pipe 22 ~ 530mm can greatly reduce the structural weight and save steel.
Looking at the overall purchase of 20G high-pressure boiler tubes, the market for 15crmoG high-pressure boiler tubes is still close to the demand and supply pattern, but there are slight changes. It is difficult to say whether the specific period will be more inclined to one side, but the shrinking market demand across the country is inevitable If the supply continues to rise, it is impossible for prices to continue to fall. Of course, the policy of limiting production is also effective, and the theoretical upper limit of supply is still under control, so the average reduction in prices will not exceed the early increase.
