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.Main uses of square tube: square tube is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry agricultural irrigation and urban construction. It is one of the key products developed.Sandbey, 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.Generally speaking, square pipe welding has a process: ignition, pressurization and thermal insulation.Minatitlan,The disadvantage of solid bending is that it has tensile thinning effect. The actual bending will produce tension at the bending point, and the tensile effect will shorten the longitudinal length of the bending line; The metal at the real bend will become thinner due to stretching.Square tube nonferrous metals, such as copper, tin, lead, zinc, aluminum, brass bronze, aluminum alloy and bearing alloy. In addition, nickel, manganese, molybdenum, cobalt square tube, vanadium tungsten, titanium, etc. are also used in industry. These metals are mainly used as alloy additives to improve the performance of metals. Tungsten, square tube titanium, molybdenum, etc. are mostly used to produce cemented carbide for tools. The above non-ferrous metals are called industrial metals. In addition, there are precious metals: platinum, gold, silver and rare metals, including radioactive square tubes.Welding is a synthetic gradient material, mechanical and physical properties between base metals.

Square pipe is the name of square pipe, that is steel pipe with equal side length. It is made of rolled strip steel after process treatment.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.It 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.resources,For improper stamping direction, simulation software shall be used in the initial stage of design to ensure that the direction of stamping parts is analyzed, and when the high-quality requirements of components require the re development of molds the direction shall be adjusted to seamless square tubes. The square tube manufacturer introduces the forming, bending and bending of square tubes. As the name suggests, the bending is compacted, and the inner and outer rollers are double with the inner and outer walls of tube billets during actual bending Compact towards the.Ship carbon steel square pipe (gb-) is a carbon steel square pipe for ship class I pressure pipe system,SandbeyThick wall hot dip galvanized square pipe, class II pressure pipe system, boiler and superheater. It is a long-term business square pipe, square pipe, seamless square pipe, galvanized square pipe and galvanized pipe. Welcome to consult. The working temperature of carbon steel square pipe wall shall not exceed ℃, and the working temperature of alloy steel square pipe wall shall exceed ℃.Reinforcing phases such as reinforcing particles, short fibers and whiskers can be added to the solder to form composites.

Carbon steel classified by chemical composition: square tube A. low carbon steel (C & le; .%); b. Medium carbon steel (C & le; . ~ .%); c. High carbon steel (C & le; .%).Administration,For structure: as pile driving pipe and bridge; pipe for wharf, road and building structure, etc.In short, the square tube production process includes these processes: tube blank & mdash& mdash; Cut off & mdash& mdash; Heating & mdash& mdash; Perforation & mdash& mdash; Pipe rolling & mdash& mdash; Sizing (reducing) & mdash& mdash; Straightening & mdash& mdash; Cut head and tail & mdash& mdash; Inspection & mdash& mdash; Packaging & mdash& mdash; Warehousing.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, 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,Sandbey22 price of galvanized square pipe, machinery industry, chemical industry, steel structure, shipbuilding, automobile, steel beam and column, special purpose, large-diameter qb square tube wall thickness classification, large-diameter qb square tube according to wall thickness Classification & mdash& mdash; Super large diameter qb square pipe, 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, then rolled into a square pipe from the round pipe,SandbeyGalvanized pipe manufacturer, 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.Sandbey,The pressurization size and time are the key to the success or failure of welding. If the square tube synthetic material is not pressurized, a large number of pores will be caused due to the pores of the material itself and the gas generated in the reaction. It is not allowed to leave the reactants in the weld, so it must be densified, usually pressurized during the reaction.For oil, the oil brush work shall be carried out in accordance with the requirements of the rule system, so as to ensure the oil brush and the oil in the correct position of the brush and avoid wrinkles.If there is only a single plane weld, the step-by-step back welding shall be adopted from the middle, that is, the arc of the section weld shall be terminated at the section arc.
