Philips Metal Industries is a leading manufacturer, exporter, stockist, and supplier of high quality Stainless Steel 321/321H Condenser Tubes that are intended to meet national and international raw material standards. The bulk of industry standard standards are covered by our diverse selection of Stainless Steel 321 Seamless Condenser Tubes. On request, we do, however, also provide SS 321 Condenser Tubes in non-standard specialized diameters. Our production schedule is made to completely satisfy consumer requests for SS 321 Seamless Condenser Tubes in terms of cost, timeliness, and details.
Heat Exchanger / Condenser SS 321/SS 321H When transporting heat between two liquids or gases that are at different temperatures, tubes are typically utilized as the element. These heat exchangers are high-performance goods made of stainless steel alloy that are primarily utilized in hot conditions. Moreover, the alloy's carbon, titanium, nickel, and chromium contents sustain this grade. The chance of carbide precipitation during welding is decreased when there is carbon content. These have better resistance to aqueous corrosion and tensile strength. The alloy SS 321/SS321H demonstrates exceptional resistance against creep and rupture. These also have a tendency to stress corrosion crack. However, these have a higher level of resistance against corrosion and metabolism. The inclusion of chromium and nickel content promotes intergranular corrosion resistance following heat treatment.
The 321 / 321H Stainless Steel Condenser Tubes are put through a variety of tests to ensure their quality. Every test is conducted while taking into account the demands and specifications of the clients, in accordance with industry standards and regulations. Tests include formability, hardness, flaring, flatness, and ultrasonic testing; third-party examination is also included. A number of other tests are conducted, including destructive, positive material identification, and pitting resistance tests.
We attach manufacturing test certificates to our items that satisfy globally accepted standards. They consist of the following: the MTC report compliant with EN 10204 3.1 or 3.2, the test reports for raw materials and mills, the NABL test report, the signed certificate from us, and the quality assurance plan. Other emphasized documents include the specification guide, welding guide, disinfection certifications, invoice, and packing information list.
