Square tube production most square tube processing is square tube pressure processing, resulting in plastic deformation of the processed steel (billet, ingot, etc.). According to the square tube processing temperature, the square tube can be divided into cold processing and hot processing. The main processing of square tube includes: rolling: the gap (various shapes) between the square tube metal blank and the rotating roll , because of the compression of the roll, the material section is reduced and the length is increased. This is a common production method for producing square tubes. It is mainly used to produce square tube profiles, plates and tubes. It is divided into cold rolling and hot rolling.For structure: as pile driving pipe and bridge; pipe for wharf, road and building structure, marine pile driving pipe, etc.Frederick Bay,The standard quantity of combustible and nonflammable square pipes is gbt- (gbt-). The representative material is l-l pipeline steel. Professional square pipes, square rectangular pipes seamless square pipes, galvanized square pipes and galvanized pipes are of high quality and low price. They are fire-resistant, waterproof, high temperature resistant, durable, safe and reliable. They are mainly used to transport combustible and nonflammable fluids with high requirements.Square tubes for petroleum cracking (gb-) are furnace tubes, heat exchangers and pipeline square tubes suitable for petroleum refineries.Raurkela,Ferroalloy is an alloy composed of iron and silicon, manganese, chromium, titanium and other elements. Ferroalloy is the raw material for steelmaking. It is used as deoxidizer and alloy element additive for steel in square tube steelmaking.Normalized: A. pearlite steel; b. Bainitic steel; c. Martensitic steel; d. Austenitic steel.Large diameter qb square tube production standard classification square tube is divided according to production standard: national standard square tube, Japanese standard square tube, British standard square tube, American standard square tube, European standard square tube and non-standard square tube.

Oil drilling pipe (yb-) is a square pipe used for internal or external thickening at both ends of oil drilling. Steel pipes are divided into turning wire and non turning wire. Turning wire pipe is connected with joint, and non turning wire pipe is connected with tool joint by butt welding.Square pipe, also known as square and rectangular cold-formed hollow section steel, is referred to as square pipe and rectangular pipe for short. The allowable deviation of wall thickness of square pipe is f and J qb respectively. When the wall thickness is no more than mm, it shall not exceed plus or minus % of the nominal wall thickness. Long term square pipe, rectangular pipe, seamless square pipe, galvanized square pipe, galvanized pipe, old brand, price advantage and quality guarantee! When the wall thickness is greater than mm, it is plus or minus % of the wall thickness, except for the wall thickness of corners and weld areas.Compared with other welding, square pipe welding has many advantages, the material only needs to be heated below the melting pointCreate brilliance,Ferrous metals refer to iron and iron alloys. Such as steel, pig iron, ferroalloy, cast iron, etc. Steel and pig iron are alloys based on iron square tube and carbon as the main added element, collectively referred to as iron carbon alloy.Viewing color: the color of the cold galvanized square tube is yellowish green, cyan white or slightly colored at a fixed angle with the sun. The color of hot-dip galvanized square pipe is silver white at a fixed angle with the sun.Structural stainless steel square pipe (gbt-) is a hot-rolled (extruded expanded) and cold drawn (rolled) square pipe made of stainless steel for corrosion-resistant pipes, structural parts and parts widely used in chemical, petroleum, light textile, food machinery and other industries.

After spraying (throwing) derusting, it can not only expand the physical adsorption on the pipe surface, but also enhance the mechanical adhesion between the layer and the pipe surface. Therefore, spray (throwing) derusting is an ideal derusting method for pipelines. Generally speaking,Frederick Bay25 galvanized square pipe, shot blasting (sand) is mainly used for the inner surface treatment of the pipe, and shot blasting (sand) is mainly used for the outer surface treatment of the pipe. Several problems should be paid attention to in derusting by spraying (throwing).Packaging strategy,Brinell hardness (HB), Rockwell hardness (HRC) and Vickers hardness (HV) are commonly used.In short,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.Fake and shoddy square tubes are easy to scratch, because the equipment of fake and shoddy material manufacturers is simple and easy to produce burrs and scratch the surface of square tubes. Deep scratches reduce the strength of square tubes.Engaged in square tube, seamless square tube, galvanized square tube,Frederick BayProcessing galvanized square pipe, galvanized tube, it shall not exceed % of the total delivery. The bending degree of qb square pipe shall not be greater than mm per meter the Demander shall cut off the interface pipe when using it. The weight of short length and non fixed length products shall not exceed % of the total delivery. For qb square pipe with theoretical weight greater than kgm and the total bending degree shall not be greater than .% of the total length. Galvanized qb square pipe for low-pressure fluid transmission,Frederick BaySquare tube weight, with standard number of gbt-. Representative materials: QA, qbqb, etc. It is mainly used for conveying water, gas, air, oil and heating hot water or steam, and its purpose is limited to general low pressure fluid.
