Ten billion Hebei Steel Pipe Manufacturing Co., Ltd. production of spiral steel pipe, the pressure fluid transmission spiral submerged arc welded pipe (SY5036-83) is mainly used for transporting oil, natural gas pipelines; pressure fluid transmission high frequency welded steel pipes with spiral seam ( SY5038-83), using high-frequency lap welding method 

 Welded spiral seam of high-frequency welded steel pipes for pressure fluid transfer. Bearing capacity of steel pipe, plastic, for easy welding and processing; low pressure fluid transmission spiral submerged arc welded steel pipe (SY5037-83), using double-sided automatic submerged arc welding or single-sided welding into the legal system for water 

 , Gas, air and steam, low pressure fluid using the submerged arc welded pipe. Now commonly used standard spiral pipe is generally divided into: SY/T5037-2000 (Ministry of standard, also known as common fluid pipeline spiral submerged arc welded steel pipe), GB/T9711.1-1997 (GB, also known as the oil 

 Natural gas industries - Steel pipe - Technical delivery conditions of the first part: Pipes of requirement class A (the current demanding GB/T9711.2 Class B steel pipe)), API-5L (American Petroleum Institute, also known as line pipe; which is divided into PSL1 and PSL2 two levels), SY/T5040-92 (pile with spiral 

 Submerged arc welded pipe) ten billion company is willing to cooperate sincerely with all levels of users, Welcome to. Tel :0317-5128533 Mobile: 13323270092 Fax :0317-6322267 Contact: Wang Yuehong Website: http://www.baiyipipe.com
