Seamless steel pipe is a steel pipe made of a whole piece of metal with no seam on the surface. This kind of steel pipe according to the production method is divided into hot tie pipe, cold tie pipe, etc., seamless steel pipe is rolled by ordinary carbon structural steel, low alloy structural steel or alloy structural steel, the outer diameter of seamless steel pipe is generally from 6mm to 830mm, the wall thickness can be from 0.8mm to 60mm, the length is generally 3m to 12m, and there are customized lengths according to demand.
Seamless steel pipe production line, which is mainly composed of a number of equipment, including heating furnace, tube rolling machine, cooler, flaw detection machine and so on. The working principle of steel pipe production line is to transform the billet into seamless steel pipe by rolling, drawing and other processes at high temperature. The seamless steel pipe produced by the steel pipe production line has good processing performance, stable and reliable quality, and is widely used in petroleum, chemical industry, machinery manufacturing and other fields.
In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
Spiral steel pipe is a spiral seam steel pipe made of strip coil plate, extruded by constant temperature and welded by automatic double-wire submerged arc welding. The spiral steel pipe will send the strip into the welding pipe unit, roll through the multi-channel roll, the strip gradually rolled up to form a circular tube blank with an open gap, adjust the pressure of the extrusion roll, so that the weld gap is controlled in 1~3mm, and the two ends of the welding joint are flush.
Cold drawing machine is a kind of equipment commonly used in the production of rebar, mainly used for steel processing and finishing. Hot rolling mill is another equipment in addition to cold drawing machine, which is mainly used for the production of rebar. The billet is heated at a high temperature and then rolled through a CNC roller. Cutting machine is another common type of rebar production equipment, mainly used to cut rebar to the required length. The rebar is cut by a high-speed rotating saw blade or other cutting tool. Bending machine is a kind of less used rebar production equipment, mainly used for bending and processing rebar. The rebar is bent and machined by using a variety of molds.

Casing is used for lining the complete borehole which has been dug into the ground to procure oil. Similar to the drill pipe, the oil well casing pipe is also subjected to axial tension, therefore they are required to be made from high-quality strong steel material. OCTG casing is large diameter pipe which are held in place in the borehole using cement.
The diameters of OCTG casing pipe range from 4.5″ to 36″. The well-cemented pipe acts as the structural component of the well and offer hole integrity. They prevent the well from collapsing when the drilling process is on. Good quality, well cemented casing can stay in place for the whole life of the well.
Oil casing is the lifeline of oil well operation. Due to different geological conditions, the underground stress state is complex, tensile, compressive, bending and torsional stress act on the pipe body. The method of rapid cooling after tempering is adopted to avoid high temperature brittleness and obtain toughness. Second, the subtemperature quenching method through the incomplete austenitizing of steel grades to effectively improve harmful elements and impurities, improve toughness. Casing is inserted into the well hole and secured with cement to help separate the rock formation and prevent the hole from collapsing, while keeping the drilling mud circulating to facilitate drilling and production.

Ductile iron pipe is a high-quality pipe material, mainly made of ductile iron. The essence of cast iron pipe is ductile iron pipe, because ductile iron pipe has the essence of iron and the performance of steel. Graphite in nodular cast iron pipes exists in a spherical form, and the size of the general graphite is 6-7. In terms of quality, the nodularization grade of cast iron pipe is required to be controlled to 1-3 grades, and the nodularization rate is ≥80%, so the mechanical properties of the material itself have been better improved, with the essence of iron and the performance of steel. The ductile iron pipe after annealing has good mechanical properties, so it is also called cast iron pipe.
The ductile iron used to manufacture the pipe is characterized by the spheroidal or nodular nature of the graphite within the iron. Typically, the pipe is manufactured using centrifugal casting in metal or resin lined moulds. Protective internal linings and external coatings are often applied to ductile iron pipes to inhibit corrosion: the standard internal lining is cement mortar and standard external coatings include bonded zinc, asphalt or water-based paint. In highly corrosive environments loose polyethylene sleeving (LPS) to encase the pipe may also be used.
