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, it is easy to weld the square tube into difficult products.Kaya machinery and other industries.Because the green billet can be pressed into any shape,Functional index analysis of square tube - angular plasticity refers to the power of plastic deformation (permanent deformation) without destruction of square tube data under load.Functional index analysis of qb square tube - commonly used are Brinell angle (HB), Rockwell angle (HRC) and Vickers angle (HV) of qb square tube. Angle is a gauge needle to weigh the soft and hard level of metal data. The angle method is rarely used to determine the internal angle in the current life. It uses the metal data surface tested under the fixed load of the indenter with a certain number and shape to determine its angle value according to the level of the object.Radovish,Square tube for automobile half shaft sleeve (gb-) is a high-quality carbon structural steel and alloy structural steel hot-rolled square tube for automobile half shaft sleeve and drive axle housing.The general delivery length of qb square pipe is mm-mm, mostly mm and mm. Qb square tube is allowed to deliver short length and non fixed length products not less than mm,Kaya80 galvanized rectangular pipe, or in the form of interface tubeSquare tubes for petroleum cracking (gb-) are furnace tubes, heat exchangers and pipeline square tubes suitable for petroleum refineries.

Square pipe for diamond core drilling (gb-) is a square pipe for drill pipe, core rod and casing for diamond core drilling.In different environments, the use efficiency of square tubes is different. According to the quality of square tubes, we will conduct progressive research on them, hoping to develop better square tubes. No matter what environment, we will make square tubes suitable for use. Then, let's introduce it to you.Among them, qb square tube is divided into: (a) by process & mdash& mdash; Arc welded square pipe, resistance welded square pipe (high frequency and low frequency), gas welded square pipe and furnace welded square pipe (b) are divided by weld & mdash& mdash; Straight seam welded square pipe, spiral weldinginstall,The difference between hot-dip galvanized square pipe and cold-dip galvanized square pipe is mainly from the following aspects: the appearance of hot-dip galvanized square pipe is slightly rough compared with cold-dip galvanized square pipe; The appearance of cold galvanized square pipe is smooth and bright.The principle is similar to that of the plate rolling machine. The bending machine can determine a circle. Adjust the height to adjust the curvature.In recent years, large-diameter seamless square tube plays a good role in economic development. Because there are many types of large-diameter seamless square tubes, the continuous casting process of large-diameter seamless square tubes is also different. What are the specific steps of the continuous casting process of large-diameter seamless square tube? As the name suggests, square tube is a kind of square tube type. Many materials can form square tube body. Its medium is used for what purpose and where it is used. Most square tubes are steel tubes, which are unpacked, leveled crimped and welded to form round tubes, Then the round pipe is rolled into a square pipe, and then cut into the required length. Generally, square tubes per package are mostly in large specifications in terms of spot, and . - ~~ - square tubes are divided into structural square tubes, decorative square tubes, building square tubes, mechanical square tubes,Kaya200 galvanized square pipe, etc. according to their uses.

Section shape classification of large-diameter qb square tube square tube is classified according to section shape: simple section square tube & mdash& mdash; Square tube, rectangular tube and complex section square tube & mdash& mdash; Flower shaped square pipe, open square pipe, corrugated square pipe, special-shaped square pipe, large-diameter qb square pipe surface treatment classification square pipe is divided according to surface treatment: hot-dip galvanized square pipe, electro galvanized square pipe, oil coated square pipe acid pickling square pipe, large-diameter qb square pipe purpose classification square pipe is classified according to purpose & mdash& mdash; Square tubes for decoration, machine tool equipment, machinery industry, chemical industry, steel structure, shipbuilding, automobile steel beam and column,KayaGalvanized pipe square pipe, special purpose, large-diameter qb square tube wall thickness classification, large diameter qb square pipe and thin-wall large diameter qb square pipe rectangular pipe are the names of square pipe and QB square pipe, that is, steel pipe with equal side length. It is made of rolled strip steel after process treatment. Generally, the strip steel is unpacked, leveled, crimped and welded to form a round pipe, and then cut into the required length. Usually pieces per bag. Qb square pipe, also known as square and rectangular cold-formed hollow section steel, is referred to as square pipe and rectangular pipe, code f and j respectively. The allowable deviation of wall thickness of qb square pipe shall not exceed plus or minus % of nominal wall thickness when the wall thickness is not greater than mm, plus or minus % of wall thickness when the wall thickness is greater than mm, except for the wall thickness of corner and welding joint area.Interpretation and observation,Cold drawn or cold rolled precision square tube (gb-) is a cold drawn or cold rolled precision square tube with high dimensional accuracy and good surface finish for mechanical structure and hydraulic equipment. The selection of precision square mechanical structure or hydraulic equipment can greatly save machining hours, improve material rate and improve product quality.Square tubes have a good performance in practical application. When we choose square tubes in practice, we should choose them according to their characteristics. We have different types of square tubes in different fields. What is the difference between the characteristics of square tubes and ordinary steel tubes? Let's introduce them today to let us have a deeper understanding of each other's tubes.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.Kaya,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.C. special performance steel: (a) stainless and acid resistant steel; (b) Heat resistant steel; (c) Electric heating alloy steel; (d) Electrical steel; (e) High manganese wear resistant steel.Special performance steel: A. stainless and acid resistant steel; b. Heat resistant steel: including oxidation resistant steel, heat strength steel and air valve steel; c. Electric heating alloy steel; d. Wear resistant steel; e. Low temperature steel; f.
