Q:What is sanitary stainless steel pipe?
Surface finish: the pipe inside and outside surface polishing treatment, the pipe surface is bright; it is a mirror. We often say is mainly to prevent the tube away the fluid material formed within the tube wall, a long time is easy to pollute and formed pipe plug.
Q:What wire is used for welding of 316 stainless steel line?
Quality inspection of welding groove preparation, according to requirements of groove size, accuracy and surface quality stipulated in construction instruction and welding process instruction, groove quality including flatness, perpendicularity and cleanness.1, check the groove processing size (height, angle, edge and blunt edge, etc.) and accuracy isDoes it meet the relevant technical standards?.2, check the groove surface roughness and surface defects (cutting gap, crack,Layer and slag) if beyond the scope of the standard should be allowed to defect, repair treatment, such as surface roughness does not reach the standard, can use abrasive grinding.3. Check the surface cleaning quality of the groove. At least 200mm of the groove face and its sidesShould be clean within the scope, without burr, slag, rust, oil, film and paint and other harmful foreign bodies.4 、 nondestructive inspection of groove surface. For welding process documentation, specify the slopeMaterials such as CY-M steel, Fe-CY-N, high temperature steel and alloy steel shall be examined on the surface for nondestructive testing (such as coloring, etc.), and the defects such as cracks shall be removed.
Q:What color is stainless steel? What color is stainless steel pipe culture?
Stainless steel tubes for industrial use are mostly iron gray, and civilian stainless steel is bright silver.
Q:What does "stainless steel pipe" DN mean?
DN is nominal diameter, nominal diameter (or nominal diameter), that is, all kinds of pipe and pipe accessories of universal caliber. The pipes of the same nominal diameter can be connected with each other and are interchangeable. It is not the outer diameter or inner diameter of the pipe in actual sense, although its value is close to or equal to the diameter of the pipe;
Q:Stainless steel pipe specification 25*2 what does it mean?
Phi 25*2 indicates that the outer diameter is 25mm and the wall thickness is 2mm. This is a small tube
Q:What are the weld sleeves for stainless steel pipes?
The process is the same as you set for the pipe welding material quota, stainless steel drop can, on the line in the budget when a show
Q:Is food grade stainless steel GB9684 304?
Food grade stainless steel is in line with the GB9684 standard stainless steel.
Q:What's lined with stainless steel?
Stainless steel lining technology is a thin-walled stainless steel tube as a carrier for welding molding, the traction winch as the power, the stainless steel liner pipe from the end of the pipeline to be pulled to the other end. After the stainless steel pipe lining is inserted, it is punched, and the gap between the inner liner and the original pipe is grouted and solidified under the condition of holding pressure. A composite tube that is tightly bonded to the original pipe and has a smooth surface. So as to achieve strong pressure, impact resistance, corrosion resistance of the overall repair purposes, to extend the service life of the original pipe for more than fifty years.
Q:316 stainless steel pipe wall mirror polishing, the smaller the roughness, the better.
From what you have described above, the difficulty lies in the roughness of the interior.You choose to finish the stainless steel tube, 2-3 finishing tubes, and then polished by solid polishing agent.
Q:Stainless steel and stainless steel pipe inside and outside polishing off, what is the difference?
The main difference between these materials is that the chemical composition is different. The corrosion resistance of 316L is stronger than that of 304 and 304L, and that of L indicates lower carbon content and stronger flexibility. Choose the key depends on the things inside, corrosion is not big, how to use the environment, there are high pressure requirements are not high.
