Wenzhou supply of thick-walled elbow / welding elbow / seamless elbow / butt elbow, Hongyuan Pipe Co., Ltd. (Contact: Feng Hongmei Contact: 15,932,713,817, QQ: 1,763,757,819) thick-walled elbow quality resistance grinding steel as the base material, piping systems used in a variety of situations. Abrasive wear, erosion, corrosion, abrasion and impact wear. The thick elbow inspection from the preparation to start until completed and put into operation throughout the entire installation process always. Each step must be a self-test and special inspection qualified before you can continue. The focus of the inspection material quality, the quality of the section of pipe cutting, welding quality group, the installation level degrees and vertical degrees, pipeline protection, non-destructive testing, hydrostatic testing and so on. Pipeline incision section requires smooth, smooth, no glitches, the end face of the vertical centerline of the tube; Quality requirements for welding weld surface should be the same width, uniform appearance of the solder wave weld width is less than l nosebleed, both inside and outside I 0-0.2mm high local depression less than 0.2mm, no undercut, cracks, lack of penetration welding migraine and other missing implicit; pipeline level, the verticality according to the requirements of GB50235-97, shall not error; pipe surface should be free of corrosion of the iron ions, no scratch , nicks, no mud, dirt contamination. Conventional process for non-destructive testing, hydrostatic testing, water rinse. In recent decades, low, development and application of rapid development of wear-resistant alloy steel, steel has good wear resistance and toughness, the production process is relatively simple, comprehensive economic and reasonable in many working conditions under the applicable , while welcomed by users. It also makes the application of thick-walled wear elbow more widespread, more and more of the low cost. The company strong technical force, advanced testing equipment, and has a non-destructive testing laboratory, production technology, advanced cold forming and thermal processing has advanced production equipment, professional technicians to ensure product quality, reliability of the Company to "customer first, reputation first, quality and price Shuangyou, courteous service" for business purposes, to ensure the best quality, the lowest price, best service, we warmly welcome new and old customers to establish long-term and stable cooperation with our relations, to create brilliant tomorrow!
