Low Carbon Mild Steel Black Seamless Pipes Tubes
Carbon seamless steel pipe is a kind of strip steel. Steel pipe with hollow cross-section, a large number of pipes used to transport fluid, such as the transportation of oil, natural gas, gas, water and some solid materials such as pipes. Steel and round steel and other solid steel compared to the same bending strength in the same bending, lighter weight, is an economic section of steel, is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, Bicycle frames and steel construction scaffolding. The use of carbon seamless steel pipe manufacturing ring parts can improve material utilization, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jackets, etc., has been widely used to manufacture steel pipe.
Mechanical Test Equipment
1.Chemical Component Analysis
2. Mechanical Properties
4. Exterior Size Inspection
- 6.Other test as customer requirement.
- Hydrostatic Testing:Inspection test pressures produce a stress in the pipe wall equal to 60% of specified minimum yield strength (SMYS) at room temperature. Maximum pressures are not to exceed 2,500 psi for NPS 3 and under, and 2,800 psi for the larger sizes. Pressure is maintained for no less than 5 seconds.
- Mechanical Tests:
- Tensile Test: Either transverse or longitudinal are acceptable for NPS 8 and larger
- Tensile tests smaller than NPS 8: Longitudinal testing only
- Flattening Test: NPS 2 and larger
- Bending Test (cold): NPS 2 and under
