Stainless steel square tube for fluid transportation (gbt-) is a hot-rolled (extruded expanded) and cold drawn (rolled) square tube made of stainless steel for fluid transportation.The second is the pickling of the square pipe. Both chemical and electrolytic methods are used when pickling the square pipe. These two methods can remove the oxide skin of the square pipe.Durango,Soft blowing treatment of molten steel after calcium treatment can reduce residual inclusions in molten steel and better wrap MNS around al CAS and other cores.Square tubes for low and medium pressure boilers (gb-) are high-quality carbon structural steel hot-rolled and cold drawn (rolled) square tubes for superheated steam tubes, boiling water tubes for low and medium pressure boilers of various structures and superheated steam tubes, large smoke tubes, small smoke tubes and arch brick tubes for locomotive boilers. Square tubes for high-pressure boilers (gb- is a high-quality carbon steel, alloy steel and stainless heat-resistant steel square tube for the heating surface of water tube boilers with high pressure and above. High pressure square tube for chemical fertilizer equipment (GB - is a high-quality carbon structural steel and alloy steel square tube suitable for chemical equipment and pipelines with working temperature of - ~ ℃ and working pressure of ~ mA.Owo,Square tube is made of different materials. It needs qualified inspection by relevant staff before leaving the factory. Square tube has a wide range of uses. Its main field is not only the construction industry, but also can be seen everywhere in our daily life. The service life of square tubes is mainly affected by surface treatment. I will explain the specific operations of surface treatment of square tubes.The inspection items, sampling quantity, sampling position and test of square tube shall be in accordance with the provisions of corresponding product standards. With the consent of the demander, hot-rolled square tubes can be sampled in batches according to the rolled root array.High quality steel (P & le; .%, S & le; .%)

Product description of square tube square tube is a light thin-walled steel tube with hollow square section, also known as steel cold-formed profile. It is a section steel with square section shape and size, which is made of Q hot-rolled or cold-rolled strip or coil as the base material, cold bending and high-frequency welding. In addition to wall thickness thickening, the corner size and edge flatness of hot-rolled special square pipe reach or even exceed the level of resistance welding cold-formed square pipe. Good comprehensive mechanical properties, weldability, cold and hot workability and corrosion resistance, and good low temperature toughness.Square tube is a kind of square tube type. Many materials can form square tube body. It is used for what purpose and where. Most square tubes are steel tubes, mostly structural square tubes, decorative square tubes and building square tubes. Square tubes can be divided into seamless and welded joints. Seamless square tubes are formed from seamless circular tubes.The principle of straightening machine is that a disc is divided into two sides to clamp round steel straight lines. Professional square tube, square rectangular tube,DurangoNational standard galvanized square pipe, seamless square tube, galvanized square tube, galvanized tube, high price, service, on-site settlement, and the other outer edge must be two equal diameters with radius R. The diameter of the reinforcement to be straightened is D, and the center distance between them is adjusted to R + R + D.Click to view,Precision pipe is a seamless pipe with high dimensional accuracy and good surface finish for mechanical structure and hydraulic equipment. The selection of precision seamless mechanical structure or hydraulic equipment can greatly save machining hours, improve material rate and improve product quality. Seamless pipe can be divided into hot rolled pipe and cold rolled pipe according to different productionReinforcing phases such as reinforcing particles, short fibers and whiskers can be added to the solder to form composites.Product description of square tube square tube is a light thin-walled steel tube with hollow square section, also known as steel cold-formed profile.

Section shape classification square tubes are classified according to section shape: simple section square tubes & mdash& mdash; Square tube, rectangular tube and complex section square tube & mdash& mdash; Surface treatment classification of flower shaped square pipe open square pipe, corrugated square pipe and special-shaped square pipe square pipe is divided into hot-dip galvanized square pipe, electro galvanized square pipe, machine tools and equipment, chemical industry, steel structure, shipbuilding, steel beam and column and special purpose are classified by wall thickness & mdash& mdash; Super square tube, square tube and thin-walled square tube plasticity refers to the ability of metal materials to produce plastic deformation (deformation) without deformation under load.Marketing Department,Stage ( & mdash; )Galvanized qb square pipe for low pressure fluid transmission Standard No.: gbt-. The representative material is the same as above. It is mainly used to transport low pressure fluids such as water, air gas, oil and heating hot water or steam. The surface of square pipe adopts hot galvanizing or cold galvanizing process.Put the pig iron for steelmaking into the steelmaking furnace according to the specified process to obtain steel. The products of steel include ingots, continuous casting billets and various steel castings made of straight square tubes. Generally speaking, steel refers to the steel rolled into various square tubes. Square tube steel belongs to ferrous metal, but steel is not completely equal to ferrous metal.Durango,Square pipe for diamond core drilling (gb-) is a square pipe for drill pipe,DurangoGalvanized square pipe, core rod and casing for diamond core drilling.Generally, chemical and electrolytic pickling are used for pickling treatment. Only chemical pickling is used for pipelines, which can remove oxide scale, rust and old coatings. Professional square tubes, rectangular tubes, seamless square tubes,Durango16 square tube, galvanized square tubes and galvanized tubes are safe, environmentally friendly and economical! The products are exported to foreign countries and are deeply trusted. Sometimes they can be used as reprocessing after sand blasting and rust removal. Although chemical cleaning can make the surface reach a certain cleanliness and roughness, its anchor lines are shallow and easy to pollute the environment.Stage ( & mdash; )
