Q:What material is RHS in the steel tube?
SHS stands for thin-walled square steel tubes in the structure and represents the self ignition ceramic composite steel tube in the material
Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
JB/T4709 recommends H10MnSi, but H10MnSi allows a lower value of strength of 430MPa, which does not match the parent material. I think American Standard is selected according to the selection of welding wire ER70S-6 GB ER50-6 wire can guarantee the equivalent strength of parent materials, and Si, Mn content can also guarantee the deoxidation effect, the weld joint is not easy to produce pores.
Q:Which is better, galvanized steel pipe or stainless steel?
Most of the use requirements are to maintain the original appearance of the building for a long time. In determining the type of stainless steel to be chosen, the main consideration is the aesthetic standards required, the corrosivity of the atmosphere in the area, and the cleaning system to be adopted. However, other applications increasingly seek only structural integrity or watertightness. For example, the roof and side walls of industrial buildings. In these applications, the construction cost of the owner may be more important than the aesthetic, the surface is not very clean can also. The use of 304 stainless steel in a dry indoor environment is quite effective.
Q:How can galvanized steel tubes be painted on the surface?
Galvanized parts are nonferrous metals, ferrous metals are black, all metal adhesion is poor;
Q:What's wrong with the 3PP anticorrosive steel tube?
PP and PE are similar in processability, and the 3PE coating can be used to produce 3PP coatings without the need for a special 3PP coating line. However, the difference between PP and PE materials makes the 3PP and 3PE coatings show different properties, which can be applied to different environments. The advantages of 3PP coating on some properties make it possible to play an important role in the field of 3PE coating. Therefore, many foreign pipeline projects use 3PP anticorrosive coating.
Q:What does "spiral welded steel pipe" DN325*10 mean?
Labeling is wrong: it should be said for 325*10, the diameter of pipe wall thickness of 10, 325;For example, the nominal diameter shall be: DN300.
Q:What are the lengths of scaffold steel tubes?
Used to build scaffolding of steel pipes in general have two kinds, an outer diameter 48mm, wall thickness 3.5mm; another kind of outer diameter 51mm, wall thickness 3mm; according to its location and role of different, can be divided into vertical pole, horizontal rod, sweeping rod, etc.. According to the technical specification for construction of steel tubular scaffold with couplers, JGJ 130 - 2011[1]. The scaffolding steel pipe should be specified with the current national standard "GB/T13793" or "straight seam welded steel pipe welded steel pipe for low pressure liquid delivery" GB/T3091 Q235 ordinary steel pipe; steel pipe steel quality should meet the requirements of current national standard grade Q235 steel "carbon structural steel" in GB/T700. The scaffold pipe shall be made of a diameter of 48.3 * 3.6 steel tubes. The maximum mass of each steel tube shall not be greater than 25.8kg.
Q:Are metal spiral tubes the same as metal bellows?
The spiral pipe is mainly used in the pipeline of petroleum and natural gas, and its specifications are indicated by outer diameter * wall thickness.
Q:What is the process of spiral steel tube production?
1. open panel inspection: after the steel plate is opened, the product line is entered, and the ultrasonic examination of the whole plate is carried out first.2., flat milling: through the anvil machine to make the original coiled steel flat, and then through the milling machine on the edge of the steel plate two sides milling, so as to achieve the required plate width, plate edge parallelism and groove shape.
Q:What does "steel pipe SC" mean?
SC (run in welded steel duitconSC is the line laying mode GB letter of wire is worn steel pipe laying (welded steel pipe, low pressure fluid) SC70 said the conductor by low pressure fluid DN70 welded steel pipe as protection pipe laying, DN70 said the nominal pipe diameter is 70mm, the nominal pipe diameter is 70mm (a series of values, the actual diameter slightly different).
