Alloy pipe

  Pipes used for petroleum mechanical processing are the necessary materials for oil exploration equipment, well-drilling equipment, machinery oil recovery equipment, facilities and accessories for oil drilling & recovery as well as integrated equipment of petroleum & natural gas collection and transmission. Our manufactory has successfully developed petroleum mechanical processing pipe with steel grade 55ksi-135ksi on its own, which has both good strength and good tenacity, uniform performance of whole wall thickness and excellent processing performance. Production Range OD: 42mm-760mm WT: 4mm-120mm Steel Grade and Properties Applicable specification: API 5CT, ASTM A519, NACE MR0175, GB/T 8162 or user’s agreement.
