Thick Wall Steel Pipe

Thick wall straight seam steel pipe, steel pipe diameter and wall thickness is less than 20 carbon steel pipe called a thick wall steel pipe. Geological drill pipe is mainly used for oil, oil chemical industry with the cracking of pipe, boiler tube, bearing and automobile, tractor, aviation with high precision tube structure, etc. Thick wall straight seam steel pipe according to the production process can be divided into high frequency straight seam submerged arc weld steel pipe and straight seam steel pipe. Submerged arc welding and straight seam steel pipe according to the different forming methods is divided into UOE, RBE, JCOE LSAW steel pipe, etc. Among them, according to various USES and different production working procedure, after. (can be roughly divided into the scaffold tube, fluid pipe, wire casing, stent tube, guardrail tube etc.)

Forging steel: use the reciprocating impact or press pressure forging hammer to make blank as we need to change shape and size of a pressure processing method.

Extrusion: steel metal is placed within the closed extrusion Jane, pressure on the side, make the metal from rules of extrusion die and have same shape and size of the finished product processing method, used in the production of non-ferrous metal material products.

Rolling: steel metal blank through a pair of rotating roll gap (shape), due to the compression of roll reduce material section, the length of the increase of pressure processing method.

Drawn steel: it is already rolling metal blank (type, tube, products, etc.) through the die drawn into section reduced length increased processing methods are mostly used in cold working.

Straight seam steel pipe domestic commonly used material is Q235A, Q235B, 0 cr13, 1 cr17 cr18ni11nb, 00 cr18ni9 cr19ni11, 1, 0, 16 mn, 20 #, Q345, L245, L290, X42, X46, X70 and X80.

Straight seam steel pipe in China is mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction. For liquid transportation, water supply and drainage. For gas, gas, steam, liquefied petroleum gas. For structure: piling pipe, bridge; Dock, road, building structural steel pipe, etc.
