Q:What kind of stainless steel square tube is used in ordinary square tubes?
General specifications of stainless steel tube at the inner diameter and wall thickness, the length can be decided according to the needs of consumers, the common market of stainless steel pipe specifications are: diameter more than 6.0mm, the wall thickness below 13mm; diameter greater than 30mm, the wall thickness is greater than 1.2mm; diameter greater than 30mm, wall thickness less than 1.2mm.
Q:304 stainless steel has several advantages, a few big advantages, the more concrete the better
304 stainless steel is a universal stainless steel material, antirust performance than the 200 series of stainless steel material stronger. High temperature resistance is also good, the general use of temperature limit is less than 650 degrees centigrade.
Q:Under what circumstances can the stainless steel pipe be welded by argon arc, and under what conditions can the arc welding be used?
From the economic point of view and flexibility, arc welding is good, from the efficiency aspect, of course, argon arc welding is higher, the effect is better, and also more mechanized. If it is small batch, it will choose arc welding.
Q:What factory uses industrial stainless steel tube to be more?
The electric power industry including nuclear power industry, the demand for stainless steel tube is large, the industry mainly uses the stainless steel seamless pipe, specific application fields: boiler pipes, water pipes, power tubes etc..According to the World Nuclear Association reports, China has 5 power stations under construction, 6 included in the plan, 19 are planning, it is estimated that power plant construction and maintenance of various types of stainless steel pipes each year about 25600 tons.
Q:Stainless steel pipes can not be less than the amount of chromium
The chromium content of stainless steel is generally not less than said first why stainless steel tube is not easy to rust 12%-304 stainless steel tube, then why stainless steel will rust stainless steel is not easy to have a great relationship with the composition of stainless steel rust. In addition to iron, stainless steel contains chromium, nickel, aluminum, silicon and so on.
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:Stainless steel pipe pickling ratio
Usage: used for contaminant removal of various types of stainless steel parts, sheet metal surface and its equipment rust, oxide skin, after welding of yellow blue black spot welding, a silver white metal surface cleaning, and surface passivation, corrosion resistance of stainless steel.
Q:SA-179 what kind of material is steel pipe?
Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
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:What are the differences in the properties of hot-rolled and cold-rolled stainless steel tubes?
From the current market, cold working processing method has been basically eliminated the hot working mode, this is caused by defects in thermal processing of stainless steel pipe: thermal processing of stainless steel tube, as in the case of heating, a molding, molding the mechanical properties of the stainless steel tube is relatively poor, so the tube doing mechanical processing will often cannot meet the needs of mechanical and physical properties.
