Alloy steel P91 pipes are similar to other austenitic stainless steel alloys, where cold working helps in the enhancement of the overall tensile and creep strength. While other annealed materials tend to form stringy chips, this P91 grade of alloy steel machines more easily due to its higher degree of cold working. LG pipes and tubes is a Mumbai based company, renowned trader, supplier, and stockiest of alloy steel p91 pipes along with other grades of steel pipes and tubes. We possess an extensive inventory of various grades of pipes to meet our customers’ demands on a daily basis. All our products go under strict testing and quality checks under our expert’s supervision. We believe in quality products and so we use high end raw materials for all fabrications.
The product works best to its capability under extremely heated temperatures and provides high pressure bearing capacity in various environmental conditions. P91 grade alloy is fabricated using the latest tools and technology which helps it work wonders in various commercial applications. It is extensively used in power plants, nuclear plants, chemical industries, industrial boilers, condensers, and various commercial sectors due to its possession of global specifications. All our products are protected with different anti-corrosives like oil, black paints, and galvanized finish.
We provide customization of our products rendering to customers’ needs and demands. Where the P91 alloy comes in different sizes ranging from ½” NB to 36” NB, also has different forms like round, rectangular, square, hydraulic, and more. It also has different ends, dimensions, shapes and, lengths. The ferritic alloy possesses extensive chemical and mechanical properties which add more substance to the product. With a minimum tensile strength of 585 MPa and minimum yield strength of 415 MPa. The improved strength of the metal helps it resist various and natural corrosions and inhibits pitting. The alloy endures higher temperatures up to 600 Degree C and has a minimum of 20 percent elongation.
