Frequently Asked Questions
Q1: What is LSAW carbon steel pipe?
LSAW (Longitudinal Submerged Arc Welding) pipe is manufactured by forming steel plates through JCOE or UOE technology, followed by internal and external welding and cold expansion.
Q2: What sizes are available for LSAW pipes?
The outside diameter (O.D.) ranges from 219mm to 1829mm (8" to 72"), with wall thicknesses (W.T.) ranging from 4mm to 50mm.
Q3: What types of surface coatings do you offer?
We provide various coatings including Fusion Bond Epoxy (FBE), 3PE, Varnish coating, and Black Oil coating to prevent corrosion.
Q4: What standards do the pipes comply with?
Our products comply with major international standards including API 5L (PSL1 & PSL2), ASTM A53, ASTM A252, EN10219, and GB/T9711.
Q5: What quality tests are performed on the pipes?
We conduct comprehensive testing including Chemical Analysis, Mechanical Property tests, X-ray inspection, Hydrostatic tests, and Ultrasonic Testing (UT).
Q6: What are the typical applications for these pipes?
They are widely used in piling, oil and gas transmission, water transport, offshore projects, and industrial structural supports.
