Oil Country Tubular Goods

Q:Which is better, galvanized steel pipe or stainless steel?: Stainless steel is good.Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel. Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.

Q:What connections are there for concrete filled steel tubular column foundations?: Application of double beam connection node usually uses "I" shape columns and steel bracket which is around the construction technology of a modern steel concrete column girder casting formed in the steel pipe outside through the two structures, the bearing pin four axis and four angles on the common components of stress transfer. The construction technology in the application is usually used at both ends of the stress transfer construction mode, through the four steel bracket to the corresponding shear stress, avoid crack width because the node contact produces clear, delayed cracks, improve anti cracking ability of regional nodes.This node model in the connection when the longitudinal reinforcement without through the tube, without bending the construction can be carried out directly, with easy construction technology, construction control difficulty, the economic benefits of construction at the same time, the advantage of low reinforcement to save. In this joint engineering technology, the key pride is to control the stress transfer of steel bracket.

Q:How seamless steel tube is formed?: Overview of two kinds of steel pipe process:1, cold drawing (rolling) seamless steel pipe: round tube to heating to perforation, annealing, pickling, leading to oil (copper), multi pass drawing (Leng Zha), the blank pipe, heat treatment, straightening, pressure test (testing), marking and warehousing.2. Hot rolling (extrusion seamless steel tube): round tube billet, heating, piercing, three roll cross rolling, rolling or extrusion, removal of pipe, sizing, reducing (diameter or reducing), cooling, blank tube, straightening, water pressure test (or flaw detection), marking and warehousing.

Q:Water, gas, steel pipes, thick steel wire means?: Often used in water, heating, gas, compressed air and vacuum lines. Can be used in pressure gauge pressure of 0.6 MPa (6 atm) steam pipe and condensate pipeline below, can also be used for conveying non erosive and non flammable and explosive media. Is divided into ordinary (working pressure is 1 MPa pressure gauge, 10) and strengthening (working pressure gauge is 1.6 MPa, 16 ATM) two. Galvanized white iron tube (galvanized iron tube). Non galvanized black iron pipe (black pipe).

Q:Is there a weld on the outer wall of seamless steel tube?: Seamless steel pipe's inner wall, outer wall, section, cross section can not see the weld seam. Because seamless steel pipe is a molding product, no late roll pressure, welding and other processes. No section, inner wall, outer wall or section, as long as there is weld, it is not seamless steel tube. The inner wall can not see the outer wall of welding seam, but it can be seen that the weld products are fake or polished goods. Some products can not be seen without friction and have weld seams on the outside wall. They are seamless treated steel tubes and are polished goods. The price is much different from the real seamless steel tube. Some bad wounding, confusing concepts, earn illegal profits.

Q:Why can't stainless steel be put together with carbon steel tube?: Stainless steel can not be put together with carbon steel because of galvanic corrosion

Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?: 200 refers to the diameter of the pipe. Personally, you should be an electrical professional, but the electrical specialty rarely uses the 200 pipe diameter unless it is used when the buried cable passes the road;

Q:Difference and application of seamless hot rolled pipe and cold drawn pipe in seamless steel tube: type3.1, seamless steel pipe according to the different production methods can be divided into hot-rolled pipe, cold rolled tube, cold drawn tube, extrusion tube and so on3.2, according to the shape of the classification of circular tubes, special-shaped tubes of the division, except the square tube and rectangular tube, there are elliptical tube, semicircle tube, triangle tube, hexagonal tube, convex shaped tube, plum shaped tube and so on3.3, according to the different material, divided into ordinary carbon structure tube, low alloy structure tube, high quality carbon structure tube, alloy structure tube, stainless steel tube and so on3.4, according to special use, there are boiler tubes, geological pipes, oil pipes and so on

Q:What are the main aspects of precision steel tubes?: Products according to their application areas are divided into: automotive, precision machinery tubes; power plants, nuclear power tubes; titanium and titanium alloy tubes; chemical tubes; varieties include colored, black; seamless; welding; general and special-shaped

Q:Is the same specification seamless steel pipe more expensive than welded pipe?: You need to see this in the interval that diameter, such as seamless pipe and welded steel tube 530*20 mm compared to 5450 yuan per ton, seamless pipe, welded steel pipe, which is 4550 yuan, small diameter 10*2 mm, seamless pipe will require far 10000 per ton, just need more than 6000
