Grade 1239 is made up of mild steel material. The IS 1239 Pipe has a chemical concentration of 0.20% carbon, 1.30% manganese, 0.040% of sulfur and phosphorous. These pipes are designed to withstand extreme pressures and temperatures in different environments. The IS 1239 MS Pipe possesses excellent mechanical properties. They have a tensile strength of minimum 330Mpa and can be easily elongated by 25.4%, and still possess good workability. IS 1239 Part 2 is used in very hazardous and extreme environments. They are a preferred choice in boilers, food processing, etc. They are available in welded, seamless, and fabricated forms. IS 1239 seamless pipe is manufactured from steel which is fully killed. These pipes are formed without welds or seams. They are extremely strong, durable, and are easy to maintain. The IS 1239 erw pipe possesses low and high-frequency resistance. These pipes are cost-effective and highly efficient in their work. They are available in sizes of 5mm to 1219.2mm. IS 1239 Class c is designed with highthickness. They are available in nominal sizes, of 3mm to 150mm. The thickness weight of this class is between 2.65mm to 5.40mm. The IS 1239 Steel Tubes are widely used in heat exchangers, oil, gas, and petroleum piping systems along with tube fluid pipes, condensers, etc. We are the leading stockist of IS 1239 Pipe in India. We have some of the best products, which are available at reasonable rates.
IS 1239 GI Pipe is coated with a protective layer of zinc. This zinc provides a smooth surface and protects these pipes against corrosion and abrasion. It helps improve the life cycle of these pipes. The IS 1239 YST 240 can be welded without the requirement of pre-heating and post-weld treatments. They are available in schedules ranging from 5 to 160 and XXS. IS 1239 heavy pipe has high toughness and possesses excellent strength. These pipes can be availed in single random, double random and custom sizes up to 7 meters or more on request. The IS 1239 Carbon Steel Pipe can be produced by cold or hot rolling process. These pipes are available with beveled, plain, and threaded tubing ends. All our products including, the IS 1239 ERW Pipe, can be custom made in desired chemical properties and sizes as per our client’s requirements.
IS 1239 square pipe is formed from coils and then run over dies. These pipes are welded in the interior and are used for various structural and maintenance purposes. The IS 1239 YST 210/355 Pipes are suited for all types of welding processes. These welded pipes can work well with 20% decreased pressures. These pipes are used in supplying water, non-hazardous gas, and so on. The IS 1239 YST 310 Mild Steel Pipe is used in low-pressure systems. These pipes are available in square, rectangular, circular, hollow, hydraulic, and various other shapes. If you have any queries or want to know more about our products, contact us.
