Stainless Steel 304 Boiler Tubes

SS 304 Boiler Tube Suppliers, Distributor of SS 304 Boiler Tubes in India, IBR Approved SS 304 Boiler Tubes exporter in India, Best Price of Boiler Tubes in Mumbai, India, Stainless Steel 304 Seamless Welded Tube Exporter in Qatar, SS 304 Boiler Square Tubing Manufacturer in Mumbai India.

Philips Metal Industries is a largest manufacturer, exporter, stockist, and supplier of high quality stainless steel 304 boiler tubes. These UNS S30400 Boiler Tubes are composed of low alloyed, heat-resistant steels that can support the load at high temperatures and pressures. Parts of energy-related machinery, including boilers, steam super-heaters, steam pipes, etc., are fitted with our SS 304 boiler tubes.

304 and 304L stainless steel tubes are very appropriate for a wide range of applications due to their many important features. They are resistant to numerous hostile conditions, oxidation, and air corrosion due to their exceptional corrosion resistance. Because of the chromium and nickel in their composition, which offer strong resistance to pitting and crevice corrosion, this corrosion resistance is further increased. Boilers and heat exchangers are frequently made using stainless steel 304 boiler tubes. They are also used in chemical facilities, the food sector, and pharmaceuticals. Stainless steel 304 tubes are the best option for applications requiring high temperatures and intense pressure because of their strong resistance to corrosion.

There are numerous uses for boiler tubes made of stainless steel 304 Heat exchangers and boilers are two of these tubes' most significant applications. They also transport heat through food processing equipment in the food industry. Chemical industries and pharmaceutical applications, where high temperature and corrosion resistant capabilities are required, also use stainless steel 304 boiler tubes.

These WNR 1.4301 Boiler Tubes are also available as hot rolled or cold drawn. Meanwhile, smaller diameter tubes and thick wall tubes with bigger diameters are delivered as cold drawn and then heat treated. Our SS Boiler Tubes are designed to meet national and international raw material quality standards and are available in a variety of sizes and forms at competitive prices for our valued customers.

There are several tests performed on Stainless Steel 304 Boiler Tubes in order to ensure its strict quality and efficiency before finally delivering it to the customers. tests such as mechanical tests, hardness tests, micro and macro tests, pitting resistance tests, positive material identification tests, intergranular corrosion tests and flaring tests are some of the tests performed.
