Indry CastleGalvanized pipe hot dip galvanized pipeWhat common sense do you need to know

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 surface of galvanized square pipe treated by sand blasting, shot blasting or pickling process is relatively clean, and the oxide scale and rust are removed, which improves the adhesion of the coating. When the installation site unconditionally adopts sand blasting and shot blasting, manual and mechanical derusting can be adopted, but the derusting quality level must be reached.Indry Castle,The strength of square tube refers to the function that the data of square tube are destroyed under static load (appropriate plastic deformation or fracture). Because the action forms of load include tension, contraction, meandering, shear and so on, because the strength is also divided into tensile strength, compressive strength, flexural strength, shear strength and so on. There is often a definite connection between various strengths. In normal use, tensile strength is often used as the fundamental strength gauge.Mechanical engineering, power plants,Indry CastlePP square tube, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, highway railings, housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, heavy transportation machinery and other welded structural parts with high load etc. Process classification: according to the production process,Indry CastleDN100 galvanized square pipe, square tubes are divided into hot-rolled seamless square tubes, seamless square tubes and qb square tubes.Halifax,Generally, chemical and electrolytic methods are usedIt should be noted that the position of the disc from the calibration line can be adjusted according to the reinforcement diameter, and R and R can be equal or different.Qb square tube, qb square tube, qb square tube, QB square tube, QB square tube and hot-rolled right angle square tube are of good quality and excellent quality. We have become a supplier of many enterprises. Qb square tube and I-beam are two products with different shapes. Under the condition of the same material, the bearing capacity of steel is the same, but their uses are very different. The shape is different. Qb square tube is a cuboid, and I-beam is in I-shape. The purpose is different. I-beam can be used as span and support. Square pipe is a little worse than span. It is no problem to do support. However, the specific selection of steel depends on the requirements of the project. Square tube practical application square tube for structure (gbt-) is a square tube for general structure and mechanical structure.

Forging square tube: a kind of pressure processing in which the reciprocating impact force of the forging hammer or the pressure of the press changes the blank into the shape and size we need. It is generally divided into forging and die forging. It is often used to produce large-scale materials and materials with large square tube size.Large fillet radius, insufficient blank holder area, easy to produce unstable wrinkles; If the fillet is too small, the resistance of the material into the die will increase in the deformation process, which may lead to tensile cracking.Steel pipe for geological drilling (yb-) is a steel pipe used by geological departments for core drilling. It can be divided into drill pipe thus increasing the large tensile stress in the force transfer area, drill collar, core pipe, casing, sedimentation pipe,Stage ( & mdash; )Plasticity QB square plasticity refers to the ability of metal materials to produce plastic deformation (deformation) without deformation under load.Generally, chemical and electrolytic methods are used

With the progress of the times and the faster and faster economic development, the places where large-diameter seamless square tubes are used are becoming more and more popularSafety and health,With the progress of the times and the faster and faster economic development, the surface effect of the square tube is quite good. The quality of the polishing process directly affects the external image of the square tube. Therefore, we must choose the appropriate polishing according to the above, and pay more attention to the polishing process of the square tube.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.Indry Castle,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.If the re inspection results are unqualified (including the items whose preliminary inspection results are unqualified and re inspection is not allowed), the supplier can submit them for acceptance one by one; Or re conduct heat treatment (the number of RE heat treatment shall not exceed times), and propose acceptance with a new batch.There are sets of MPM and sets of MRK pipe mills in the world. Strength refers to the function of qb square tube data being destroyed under static load (appropriate plastic deformation or fracture). Because the action forms of load include tension contraction, meandering, shear and so on, because the strength is also divided into tensile strength, compressive strength flexural strength, shear strength and so on. There is often a definite connection between various strengths. Long term square tube square rectangular tube, seamless square tube, galvanized square tube and galvanized tube have no turnover to avoid price difference, and the price is % higher than the market price! The price of more than one ton is higher! In normal use, tensile strength is often taken as the fundamental strength gauge needle.
