201/202/304/316 marine grade stainless steel pipe
Bhawal Steel Agency is one of the most astonishing manufacturers, suppliers, and stockists of high-quality marine grades stainless steel pipes. These marine-grade stainless steel are made of certified and thoroughly tested raw material. These grades are accessible in various sizes, thickness and dimensions. Bhawal Steel Agency is the most largest supplier of marine grade stainless steel pipes. We supply these pipes world wide. These marine grade stainless steel pipe are made with extra robust elements.
Marine grade stainless steel pipes are made from a great combination of chromium, molybdenum, nickel and manganese. These elements have excellent corrosion resistive properties. This grade also includes 1.2% of carbon and other alloying elements which protects an alloy from corrosion and stress cracking. Marine grades have the ability of working with high chloride content and heat.
Marine grade stainless steel pipes are highly stable. These pipes are widely used for transmitting fluids, sea water, acids and chemicals from one place to another. These pipes are also enriched with high scalability and strength. Marine grades have high elongation and melting point. Marine grade stainless steel pipes have great thermal conductivity and non-magnetic properties. There are various grades which are categorized according to the temperature in degrees and applications.
Marine grades are further differentiated into various categories like 304 grade, 304L grades, 316 grades, 316L grades, etc. The application of these grades depends upon the heat temperature, weather conditions, and types of fluids being transferred. These pipes are extremely ductile and made for long term usage. These pipes constantly get attacked by chloride present constituents; which is why the cleaning of the pipes time to time is very important.
Marine grade stainless steel pipes also provide great protection from carbon precipitation, erosion, and reduction. All these marine grades are rigorously manufactured considering national and international standards.
