1.4550 Boiler Tube and SS 347 Seamless Tube supplier in India

ASTM A312 TP347 Stainless Steel Tube

ASTM A312 TP347 Stainless Steel Tube

ASTM A312 TP347 Stainless Steel Tube producers and distributors in India

The ASTM A312 TP347 Stainless Steel Tube can be described as austenitic stainless steel that has been stabilized with columbium. The addition of columbium in the 347 Stainless Steel Tube composition enhances its performance under high temperatures (around 800 degrees C) and high oxidation conditions. They can last for many years without much maintenance, and they have increased strength and high durability.

We are one of the top manufacturers of SS 347 Seamless Tube in India. Here you will get 347 SS Pipe available in different sizes ranging between ½” to 24”. We can customize different aspects of these products according to the requirements given by the clients and offer fast deliveries. Using advanced equipment in Stainless Steel 347 Heat exchanger Tube manufacturing makes everything hassle-free, and the work is done with precision. The products are manufactured in seamless conditions, and they possess high weldability. The welded pipes can be fused electrically, and they range between 6” to 100”. We manufacture different types of pipes in the given material grade in various dimensions.

We have an experienced team who supervise the manufacturing process of 1.4550 Pipes to ensure that everything is done perfectly. Our products are high in quality, and they have dimensional accuracy. We follow the national and international standards for raw materials along with the set guidelines for manufacturing SS 347 Boiler Tube. This ensures product quality and safety. We also package the UNS S34700 Welded Tube carefully in a wooden box to prevent all types of potential damages caused during transportation.

What is ASME SA 213 TP 347 Boiler Tube?

An advantage of using is that the A213 TP 347 Stainless Steel Coiled Tube Heat Exchanger can be considered for those applications that require being heated intermittently between an elevated temperature range between 800ºF to about 1650ºF. Or the SA 213 TP 347 Stainless Steel Seamless Boiler Tubes could also be used for welding under conditions which avert the need of a post-weld annealing treatment.
