The Sigma brand is positioned as an advocate for worry free stainless steel home decoration pipes in China. Its products are developed with a focus on the needs of the home decoration market. Through the advantages of high cost-effectiveness and good service experience, the Sigma brand characteristics are gradually rooted in the consumer market, and through continuous improvement of the service system, it has won a good reputation and formed a unique Sigma brand style. 1. Gas shielded welding, under argon protection, does not oxidize the chromium and nickel on the surface of stainless steel during welding, preserving the original characteristics and corrosion resistance of stainless steel. 2. After forming and welding processes, bright solid solution stainless steel fittings must undergo a solution treatment at 1050 ℃ to eliminate internal stress caused by deformation, reduce stress corrosion, restore intergranular changes during welding, dissolve carbides in the welding heat sensitive zone in austenite, and prevent adverse effects on the performance of austenitic stainless steel. 3. Acid pickling passivation can produce a thin, dense, and hard passivation film on the inner and outer walls of water pipes and fittings. The presence of passivation film is the fundamental reason for stainless steel to prevent corrosion. 4. Sealing materials are the lifeline of stainless steel pipelines, and the service life of sealing materials determines the service life of stainless steel pipeline systems. The sealing ring provided by Sigma is made of imported silicone raw materials from abroad, and the physical properties of the material are much higher than those of domestic rubber materials. 3、 Four advantages of SKUM: Reliable and safe connection, high connection strength, and vibration resistance. Making the connection part "dead" at once avoids the possibility of loose joints. Advantage 2: Maintenance free, cost saving, and economic advantages. During the service life of the building, there is almost no need to update and maintain the fittings, which greatly saves maintenance and repair costs. Advantage 3: Flexible installation method SKUM double clamp pressure pipeline connection meets the requirements of embedded installation, greatly reducing the possibility of water pipe leakage in concealed environments. The flexible installation meets the requirements of the national CECS 153:2003 "Technical Specification for Thin walled Stainless Steel Pipeline Engineering for Building Water Supply". Advantage 4: Convenient and fast construction. SKUM double clamp pressure pipeline connection is extremely easy to install on site, with installation time only one-third of welding or threading pipe fittings, shortening the construction period and reducing costs, avoiding the occurrence of water leakage.
