Boiling water pipes and superheated steam boiler tubes on ordinary stainless steel pipe on it. The stainless steel pipe with high-pressure and ultra-high pressure boiler superheated steam pipes, heat exchangers and pressure equipment must use a high pressure, high temperature and to ensure a good surface state, mechanical properties, and process performance. We must verify its mechanical properties, and make flattening and hydrostatic test, high-pressure boiler with stainless steel pipe also required to do rigorous testing and non-destructive testing related to grain size. Shandong Jinding Stainless Steel Pipe Co., Ltd. specializes in the production of pressure vessels, stainless steel pipe, stainless steel pipe for boiler, heat exchangers, stainless steel welded pipe, 441 stainless steel pipe, the company has advanced production equipment (automatic pipe welding machine, online eddy current testing, on-line solution bright annealing furnace, polishing equipment) as well as domestic first-class test equipment (mechanical testing equipment, process performance test equipment, pneumatic, hydraulic test equipment, intergranular corrosion test equipment, grain size test equipment, nondestructive testing equipment). Strength of the company. And Hongda Group, Halma, Luxi equipment and hundreds of enterprises to establish a long-term relationship. Stainless steel welded pipe size jargon a nominal size (nominal size specified in the standard, 436L stainless steel welded pipe, also specified in the contract ordering size) and actual size (actual size of the resulting production process, the size will be greater than or less than nominal size, stainless steel pipe, this is called bias) b deviation (actual size in the production process is difficult to achieve nominal size of the standard, so the actual size and allow the difference between nominal size, which is the deviation) and tolerance (standard sum of absolute values ??of positive and negative deviations of the provisions called tolerance) 409L stainless steel pipe, Jinding Industry (certified), stainless steel pipe provided by the Shandong Jinding Stainless Steel Pipe Co., Ltd .. Shandong Jinding Stainless Steel Pipe Co., Ltd. (www.ss304L.com) (www.ss304L.com) is Dezhou, steel leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy client needs.
