Carbon Steel Pipe Production

Carbon steel pipe can be divided into seamless steel pipe, straight seam steel pipe, spiral steel pipe, high-frequency welded steel pipe. Rolled seamless carbon steel pipe is the raw material of round tube, tube embryo to be cut through the cutting machine into a length of about 1 m of blank, and the conveyor belt to the furnace heating. The billet is fed into a furnace and heated at a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a key issue. After the round tube billet to go through the pressure piercing machine to wear empty. Generally more common punching machine is conical roller piercing machine, this punching machine production efficiency is high, product quality is good, perforation expansion diameter large, can wear a variety of steel. After piercing, the round tube blank has been three-roll cross-rolling, rolling or extrusion. Squeeze after the tube diameter. Sizing machine through the high-speed rotation of the cone drill bit into the steel embryo drilling, the formation of steel pipe. The inner diameter of the pipe is determined by the outside diameter of the sizing bit. Steel pipe after sizing, into the cooling tower, through the water cooling, the cooling pipe, it is necessary to be straightened. After straightening by the steel pipe sent to the metal detector (or water pressure test) for internal testing. If the pipe has cracks, bubbles and other problems, will be detected. After the quality of steel pipe but also through rigorous manual selection. After the quality inspection of steel pipe, spray paint with the number, size, production lot number. And suspended by the crane into the warehouse.

Cold drawn (rolled) carbon steel seamless steel pipe: round tube → heating → punching → start → annealing → pickling → oiling (copper) → multi-pass cold drawing (cold rolling) → tube → heat treatment → straightening → water pressure test (testing) → marking → storage

Carbon steel seamless steel pipe because of its manufacturing process is different, is divided into hot-rolled (extrusion) seamless steel tubes and cold drawn (rolled) seamless steel pipe two. Cold drawn (rolled) tube is divided into two kinds of round tube and special-shaped tube.

In addition, GB / T17396-1998 (hot-rolled seamless steel pipe for hydraulic support), GB3093-1986 (diesel engine high-pressure seamless steel pipe), GB / T3639-1983 (cold drawn or cold-rolled precision seamless steel pipe), GB / T3094-1986 (cold drawn seamless steel pipe shaped steel pipe), GB / T8713-1988 (hydraulic and pneumatic cylinder with precision diameter seamless steel pipe), GB13296-1991 (boiler, heat exchanger with stainless steel seamless pipe), GB / T14975 (Seamless Steel Tube for Automotive Axle Bushings), API SPEC5CT-1999 (Casing and Tubing), GB / T14976-1994 (Seamless Steel Pipe for Fluid Conveying) Specification) and so on.

The raw material of carbon steel pipe is round pipe billet. The round pipe billet is cut by the cutting machine and processed into the billet with the length of 1 meter. And then sent to th furnace tobe heated by the conveyer belt. The billet is fed into a furnace and heated at a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a key issue. After the round tube billet to go through the pressure piercing machine to wear empty. Generally more common punching machine is conical roller piercing machine, this punching machine production efficiency is high, product quality is good, perforation expansion diameter large, can wear a variety of steel.

Galvanized Steel Pipe

Galvanized steel pipe is the surface with hot-dip galvanized or electro-galvanized layer. Galvanized steel can increase corrosion resistance and prolong life. Galvanized steel pipe is widely used, except for water, gas, oil, generally low-pressure fluid line pipe, also used oil heater oil industry in particular, marine oil wells pipes, pipelines, chemical coking equipment, condensing coolers, washing coal distillate oil exchange used tubes, as well as the bridge piles, mine tunnel support frame with a pipe.

Galvanized steel pipe is divided into cold galvanized pipe and hot galvanized pipe, which is more extensive use of galvanized steel, hot galvanized steel is widely used in construction, machinery, mining, chemical, railway vehicles, the automotive industry, roads, bridges, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries. hot galvanized pipe is molten metal reacting with the iron matrix alloy layer, so that the substrate and coating combination of both. Galvanized pipe is first pickled, the steel surface in order to remove iron oxide, after pickling, cleaning tank by mixing an aqueous solution of ammonium chloride or zinc chloride and zinc chloride or ammonium chloride solution, and then into hot dip tank. Galvanized with coating uniformity, strong adhesion, long life and other advantages. Hot dip galvanized steel substrate with molten bath complicated physical, chemical reactions, the formation of corrosion-resistant zinc-iron alloy structure closely layer. Alloy layer and layer of pure zinc, steel base blend. Therefore it resistant to corrosion.
