- Q:How can galvanized steel pipe be connected with stainless steel pipe?
- Attention should be paid to the zinc coating at the side of the groove before welding. It is OK to brush silver powder after welding. There is a lot of information about the welding of carbon steel and stainless steel. Just check it online.
- Q:What is the production process of seamless steel tube?
- Main production process of cold rolled (drawn) seamless steel tube:Blank preparation, pickling, lubrication, cold rolling (drawing), heat treatment, straightening, finishing and inspectionThe production process of seamless steel tube in general can be divided into two kinds of hot rolling and cold drawing, cold-rolled seamless steel pipe production process than hot-rolled billet to complex, first to three roller rolling and extrusion to sizing test, if the tube through the cutting machine cutting surface without crack growth response after cutting blank about one meter. Then enter the annealing process, annealing and pickling to use acid pickling liquid, should pay attention to the surface if there are a lot of bubbling, if there are a large number of bubbling pipe shows that the quality is not up to the standard. The appearance of cold rolling seamless steel tube shorter than hot-rolled seamless steel pipe, cold rolled seamless steel pipe wall thickness is generally higher than hot-rolled seamless steel pipe to be small, but the surface looks better than thick wall seamless steel pipe is more bright, rough surface is not too much, not too much burr diameter.
- Q:How to identify stainless steel pipe and steel pipe?
- The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc.. Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline. Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.
- Q:Is there a weld on the outer wall of seamless steel tube?
- As you have said this, you have to fake goods is seamless, commonly known as to seamless steel pipe, seamless steel pipe is welded pipe weld reinforcement, and then go inside and outside the weld is worn away, and then burn side is that you say is that, after you can see the wall friction of a weld, is not too obvious. Like a polished, but no wall bulge, can not see the seam,
- Q:What is the outer diameter of the steel tube?
- The outer diameter refers to the maximum diameter including the thickness of the steel tube, the inner diameter is the length of the hollow part inside, and the outer diameter minus the inside diameter is the thickness of the steel pipe
- Q:What is the meaning of "DN" and "Phi" in the dimensioning of steel pipe diameter and how to apply the mark?
- DN is a kind of Engineering path, not the actual value, due to the different standards, so the actual corresponding values is not the same; phi is refers to the actual value, the same national standard pipe inside the steel pipe, the actual value is the same, for example, GB/T8163 and GB GB fluid pipe spiral pipe and GBT/T9711.1 GB/T12459 the same nominal diameter corresponding to the actual value is the same as the actual value; and American Standard steel standard ANSI B 16.38 and ANSI B 16.9 standard American Standard fitting the same nominal correspondence is the same. If marked, the nominal diameter should be added DN, and the actual value can be omitted.
- Q:How to make the steel pipe spray paint is not easy to fall off?
- First you will rust steel, to clean, good quality alkyd rustproof paint, completely dry after brushing paint, color to see his kind of love.
- Q:Theoretical weight of 25*25*1.5 square steel tubes
- Square steel tube, referred to as square tube, also known as square tube, is a square pipe of a kind of name, that is, the length of the same steel pipe. The strip is rolled by process. Generally, the strip is disassembled, leveled, crimped and welded to form a round tube. The tube is then rolled into square tubes and cut to the required length, usually 50 pieces per package.
- Q:What's wrong with the 3PP anticorrosive steel tube?
- At present, mainly foreign related products come out, for some countries with relatively high ambient temperature, and PP than PE to hard, so as to avoid scratching coating.
- Q:45 and 316 which steel tubes are of high hardness?
- This depends on the heat treatment state, if 45 steel, 314 stainless steel without heat treatment, 316 stainless steel hardness, if the heat treatment, that is 45 steel hardness.
We are a professional manufacturer of seamless steel pipe of large diameter seamless steel pipe special large modern enterprise R & D, according to ASME, ASTM, API, EN, GB and other standard production maximum diameter of 1200mm, maximum wall thickness of 200mm carbon steel , alloy steel and stainless steel products. Such products are mainly used in nuclear power, super / ultra-supercritical power plants, ethylene, oil refining, coal chemical industry, oil and natural gas, marine engineering, military, metallurgy and the large-scale structure and other important areas.
