Seamless pipe possesses a hollow section and without seam around the strip steel. It is made with solid bar or steel ingot by perforating machine. As the facture process does not include any welding, seamless pipes are considered to be stronger and more durable. Generally speaking, seamless pipe has better pressure resistance and security than other classifications, and was usually more easily available than welded pipe.

Q:What kind of stainless steel square tube is used in ordinary square tubes?
Stainless steel tube is widely used, of course, there are certain reasons, of which the most important is its long service life, good corrosion resistance, and lighter weight, but the strength of large, reduce the load for the product, increase its capacity, so that consumers with more rest assured.
Q:304 stainless steel pipe, 20*2 pressure, how many kilograms?
304 stainless steel is a brand of stainless steel produced according to the ASTM standard in the United states. 304 is equivalent to 0Cr19Ni9 in our country(0Cr18Ni9) stainless steel. 304 chromium 19%, containing nickel 9%. The 304 is the most widely used stainless steel, heat-resistant steel, steel, steel industry utility. For food production equipment, general chemical equipment, nuclear energy, etc..
Q:How can the stainless steel tube eliminate stress?
Or artificial stress, method: stresses both ends of the steel pipe fixed by the mold, through high-frequency shocks, so that the internal stress relief of the steel pipe
Q:Why is the outer diameter of 1 inch galvanized pipe 33.7? And the outer diameter of one inch stainless steel pipe is 25.4
The 1 inch galvanized pipe refers to the nominal size holes of 1 inches of water, the outer diameter is 33.7, its diameter fits a 1 inch pipe thread wire, and one inch stainless steel tube outer diameter is 25.4 that of the tube is in diameter standard specifications.
Q:304 stainless steel has several advantages, a few big advantages, the more concrete the better
304 stainless steel has excellent stainless steel corrosion resistance and better intergranular corrosion resistance. The oxidizing acid, in the experiments: the concentration of more than 65% of boiling temperature following nitrate, 304 stainless steel has high corrosion resistance. Alkaline solution and most organic acids and inorganic acids also have good corrosion resistance.
Q:What's the difference between stainless steel 304 and stainless steel 202?
202 stainless steel is one of the 200 series stainless steel, the national standard model is 1Cr18Mn8Ni5N. 200 series stainless steel is low nickel, high manganese stainless steel, nickel content, manganese content of about 8%, is a nickel type stainless steel.
Q:What wire is used for welding of 316 stainless steel line?
Inspection of assembly and tack welds;1, check the geometry and shape after assembly, whether it conforms to the provisions of the drawings. :2, assembly and assembly clearance is 1.5 - 2mm, using TIG welding, three point positioning welding,The welding seam position for the clock 3 points, 9 points and 12 points, the welding materials used should be the same as the welding materials, welding length is 10 15mm, welding requirements and guarantee no defect, the wrong side is less than 1.5 2mm.3, the group is not allowed to use strong assembly, the joint wall must be flush.4, when welding, there must be no air, slag, tungsten and crack.
Q:What are the specifications of stainless steel decorative pipes?
For the steel to withstand the pressure to the hydraulic test to test its ability and quality, leakage, soaked or expansion for qualified does not occur at the prescribed pressure, some steel according to the requirement of standard or edge test, flaring test and flattening test.
Q:Stainless steel pipe welding interface leakage, how can we not leak?
The gap between the group and the WPS should be corresponding, and the gap is too big or too small, which will lead to welding defects;
