Product Q&A
Q:What is the difference between seamless pipes and welded pipes?
A:
Structure: Seamless pipes have no welds, and welded pipes have longitudinal or spiral welds; Strength: Seamless pipes have higher overall strength and are suitable for high-pressure scenarios (such as boilers and hydraulic systems); Cost: The production process of seamless pipes is complex, and the price is 10%-30% higher than that of welded pipes.
Q:How to choose the material of seamless pipe?
A:
General environment: choose Q235 or 20# carbon steel (low cost, easy to process); Corrosive environment: choose 304/316L stainless steel or galvanized seamless pipe; High temperature and high pressure: choose 15CrMo, 12Cr1MoV and other alloy pipes (specific temperature and pressure parameters must be provided).
Q:How to detect the quality of seamless pipes?
A:
Appearance: no cracks, folds, or scars on the surface, and uniform wall thickness; Non-destructive testing: ultrasonic (UT) and eddy current (ET) detection of internal defects; Pressure test: water pressure test (such as water pressure 10MPa, pressure maintenance for 5 minutes without leakage).
Q:What are the main applications of seamless steel pipes?
A:
Used for industrial pipeline systems (water, oil, gas), machinery manufacturing (drive shafts, hydraulic cylinders), construction (bridge supports, pile foundations), and chemical/petroleum (corrosive medium transport, oil extraction).
Q:What surface treatments are available for seamless pipes?
A:
Options include bare, black painted (varnish coating), galvanized, oiled, and advanced anti-corrosion coatings such as PE, 3PE, and FBE.
