Product Overview
Seamless steel pipe is manufactured by solid steel billet piercing, hot rolling and cold drawing process, without any welding seam on the pipe body. Compared with welded steel pipe, seamless pipe features higher pressure resistance, better structural stability, uniform wall thickness and smooth inner and outer surface. It is widely used for high-pressure fluid transportation, boiler power plants, petroleum chemical industry, mechanical processing and structural engineering. All products comply with international standards and can pass third-party inspection.
