Material Introduction

Carbon steel is widely applied for production of pipe fittings because of its prominent advantages such as low cost, great processability and easiness of smelting, even though it does have some disadvantages. For example, it could not withstand the corrosion by air, acid, alkali and sodium. Below Ductile-to-Brittle Transition Temperature, it will become brittle. In addition, it will be magnetized when in magnetic fields.

Production Process

Generally, carbon steel type and production process selected for manufacturing of carbon steel pipe fittings are determined by the outer diameter and wall thickness of the finished pipe fittings required. Please refer to the situations listed below.

Outside diameter Wall thickness Material Production process
1/2 inch to 24 inches STD-SCH80 Seamless steel pipe Hot press forming by mandrel
6 inches to 30 inches SCH160, SCHXXS and above Seamless steel pipe Hot press forming
6 inches to 100 inches ≤20mm Steel plate Cold forming by mold
>20mm Hot forming by mold

Once formed, carbon steel pipe fittings will first go through different heat treatment processes based on the raw material grade. Then non-destructive testing will be conducted for the surface, which includes magnetic powder detection and dye penetration inspection. If qualified, the surface will go through shot blasting process and then could be imprinted and packaged according to customers’ requirements.
