- Q:Is the same specification seamless steel pipe more expensive than welded pipe?
- Specifications of the same kind of seamless steel pipe than welded pipe prices are generally about 30% high, large diameter difference is greater.
- Q:Are the welded and galvanized tubes the same weight?
- The same specifications of welded pipe and galvanized pipe weight is not the same, the general welding tube weight, galvanized pipe light.
- Q:How long are the seamless tubes? Are they six meters long?
- The length of the seamless tube is 3000~12000mm, including 6 meters.
- Q:How to distinguish seamless pipe and welded pipe?
- If there is a weld seam in the fracture surface, whether it is inside or outside the pipe, then it is the welded pipe
- Q:What type of steel pipe for security windows?
- General anti-theft window through the round tube is 3 cm square tube, 22.5 mm diameter round tube, also can use all square tube to do, if you want to median 304, the pipe is estimated more expensive, the market to do the price in 60 to 110 range. As for plastic steel, Anhui conch brand, the price of 180 this way. Aluminum alloy 110 to 230 specific look what material?!
- Q:What's wrong with the 3PP anticorrosive steel tube?
- Most of the large pipes in our country use 3PE coating, and 3PP and 3PE coating belong to multilayer coating system. It consists of epoxy powder, intermediate layer adhesive and outer layer of PP (polypropylene) jacket.
- Q:Is there any difference between thermal expansion seamless steel pipe and seamless steel pipe?
- One is thermal expansion on a bar, that is, piercing between the bars and expanding the tube with a little bit of mandrel. The other is to expand the formed tube before it is heated so that the defects in the pipe will be enlarged. Comparatively speaking, the quality of the first kind is better than the second, and you should belong to the second kind. Compared with the original seamless seamless tube, the quality and chemical properties are certainly different. The price will be cheaper, too.
- Q:What's the use of steel pipe?
- (processing workshop of Tianjin steel pipe company as a result of the steel pipe truss structure, the actual steel saving up to 42.9%), with a steel pipe manufacturing highway bridge can not only save steel, simplify the construction, but also can greatly reduce the coated area, saving investment and maintenance costs.
- Q:What is a tight steel tube?
- JDG pipe is the replacement of traditional PVC and SC pipes and other traditional wire conduits. It is a breakthrough in the field of building electrical field using new materials and technologies. The JDG pipe adopts the cross connecting ground wire of galvanized steel pipe and thin-wall steel pipe, overcomes the defects of complicated construction and large construction loss of common metal pipe, and solves the problems of poor fire resistance and difficult grounding of PVC pipe. Because the JDG pipe material is more expensive than the ordinary pipe material, it is more used in the construction, such as comprehensive wiring, fire protection wiring and so on.
- Q:What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
- The pipe material of heating pipe network should be designed according to the requirement. When the design is not specified, the following requirements shall be met:1 when the pipe diameter is less than or equal to 40mm, welded steel pipe shall be used.2 when the pipe diameter is 50 ~ 200mm, welded steel pipe or seamless steel pipe shall be used.3 when the pipe diameter is greater than 200mm, spiral welded steel pipe shall be used.
