  On Tuesday, Vietnam's hot-rolled coil prices stabilized and weakened, and import transactions were deserted. As the yuan weakened further, US dollar quotations for Chinese resources edged lower again, although official quotations from Chinese mills were largely steady this week. The FOB price of large SS400 steel mills is maintained at US$600-605/ton FOB, the feasible range for some large steel mills is US$565-570/ton FOB, and the feasible price for Southeast Asia is US$590-600/ton CFR. In general, compared with local resources, the price advantage of imported resources is not obvious, and local Vietnamese buyers have also purchased local resources. The quotation of FHS SAE1006 hot coil this week is at 610 US dollars / ton CIF Ho Chi Minh, and the price of Hefa is 595-600 US dollars / ton CIF. This week, India and South Korea's offer to Southeast Asia has decreased, and India's domestic demand has recovered before the festival. The price has been boosted, and exporters ha...

  4130 is a chromium-molybdenum alloy material. Because of the addition of various alloying elements, the pipe has high strength, certain corrosion resistance, good toughness and weldability, and is easy to process. While 4130 seamless pipe has a certain strength, its own weight is lighter than steel pipes of other materials, so it is often used in bicycle manufacturing, automobile manufacturing and aircraft manufacturing.

Cars are the daily necessary means of transportation for the public. The manufacture of cars is inseparable from steel pipe products. Let us take a look at the parts of the car that are composed of steel pipes: CCB pipe fittings CCB is mainly used to support man-machine interface control equipment and decorative parts, and at the same time form a safety system with other safety structures. The structure is simple and mainly includes a pipe beam, a side end support, a pipe column fixing support assembly, a lower support leg and an auxiliary support. Seat post It acts as a support structure within the car seat cover, allowing the seat to retain its structural shape. Trunk hinge The trunk hinge is the connecting mechanism of the trunk door of the car. Due to the opening angle of the trunk door, the hinge needs to bear the weight of the trunk door, so the hinge also needs to play a supporting role. Door anti-collision tube When the side door is hit, the sturdy high-strength anti-collision ...

  In 2012, a construction project in Ordos consisted of 6 high-rise towers and 3-storey podium. The load-bearing skeleton of the project was mainly straight seam circular pipe columns, so the quality of the straight seam welded pipe of this project is related to the quality and progress of the entire project. Analysis of the key points and difficulties in the production of straight seam welded pipe columns 1. The flatness of the cutting surface when the welded pipe body is rolled and the material is broken is the focus and difficulty of the entire project 2. The angular deformation control and corrective measures of the assembled wings are the focus of this project 3. The selection of the welding method and welding specification of the welded pipe and the annular flange welding seam is the difficulty of the project Cutting tool selection and weld seam control 1. When cutting, cut in a circle, and mark the cutting position in advance, which is convenient to control the cutting machi...

  Seamless steel pipe is perforated by the whole round steel pipe, there is no weld on the surface of the steel pipe, called seamless steel pipe. Thick - walled seamless steel tubes are generally produced by hot rolling process, while thin - walled seamless tubes are mostly produced by cold rolling process. It is generally considered that the pipe wall thickness is less than 0.05 for thin wall steel pipe, greater than 0.05 for thick wall seamless pipe. In use, thin-walled pipes are mainly used for common pipes, while thick-walled pipes are used for pipes requiring pressure, such as: various mechanical processing, thick-walled parts processing, bridge piling, seabed piling and high-rise building piling industries. The main materials of thick wall seamless tube are: 10#, 20#, 35#, 45#, 20Cr, 40Cr, 42CrMo, 16Mn, 27SiMn, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo, etc. Theoretical weight calculation formula of thick wall seamless stainless steel :(outer diameter - wall thickness) × wall thick...

  Recently, the futures shock adjustment, the overall market mentality is weak. From the perspective of raw materials, the tube billet continues the weak adjustment. Today, the billet price rebounded slightly, and the tube billet price may stabilize. In the market, customer feedback demand in August compared with July did not appear significantly better, the market large inventory passively increased, but considering the recent high temperature weather exit, September demand or marginal turn better. To sum up, it is expected that today's seamless price to weak shock adjustment, demand or marginal turn.
