Philips Metal Inustries is the largest manufacturer, exporter, stockist, and supplier of high quality Stainless Steel 321 / 321H IBR Pipes and Tubes that are intended to meet national and international raw material standards. The oil and gas, petrochemical, shipbuilding, nuclear power plants, chemical, desalination, water treatment, and other industries use these stainless steel 321 seamless IBR pipes and tubes. Utilizing state-of-the-art machinery, we produce these SS 321 IBR Pipes and Tubes, scrutinizing their quality to ensure our customers receive superior products.
The flexible and stabilized grade of SS 304 is called SS 321. The grade's good ratio of nickel and chromium, along with a little quantity of titanium, shields it from the possibility of intergranular corrosion resistance following heat treatment. The grade provides good strength and corrosion resistance against a variety of environmental and aqueous corrosion types. In addition, the grade has excellent forming qualities, doesn't need to be annealed after welding, and has a high degree of hardness in hot environments. 321 grades have excellent strength, outstanding resistance to corrosion, and exceptional durability even in cryogenic conditions.
The severe quality assurance method is implemented throughout our entire production department. Our streamlined production employs a comprehensive quality management system. To produce more efficient products, the production process and methods are carried out by worldwide standards. The materials are inspected using the following tests: sigma detention, ultrasound radiography test, pitting corrosion test, natural circulation stability testing, and mechanical test. Some of the tests we undertake include thermal performance, hardness, impulsive line leak, positive material, hydrostatic, chemical, destructive/non-destructive, intergranular corrosion, and vacuum 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.
