347 Stainless Steel Pipe is a corrosion-resistant and heat-resistant pipe made from grade 347 stainless steel. This particular grade of stainless steel is characterized by its high chromium and nickel content, along with the addition of columbium/tantalum, which provides enhanced resistance to intergranular corrosion and oxidation in high-temperature environments. These pipes and tubes exhibit exceptional heat resistance, maintaining their mechanical properties at elevated temperatures.

ASME SA312 Stainless Steel TP347H Pipes are easily weldable and can be welded using various welding techniques without the risk of intergranular corrosion or sensitization. The addition of columbium/tantalum in 347 stainless steel helps prevent intergranular corrosion, making these pipes ideal for applications where exposure to corrosive substances is a concern.
Since 347 stainless steel is specifically designed to resist intergranular corrosion, specialized tests are performed to confirm its resistance to this type of corrosion. NDT(Non-Destructive Testing) methods like ultrasonic testing, radiographic testing, and dye penetrant testing are employed to detect any surface or subsurface defects in the pipes without causing damage to the material.

Stainless Steel 347 Round Pipes are capable of withstanding the low temperature up to any extent without losing their properties. The strength of pipes doesn’t degrade making the pipes weaken. Hence they are highly preferred by industries where sub-zero temperature exists. SS 347H is frequently used in a high stress, high corrosion settings where exposure is significant. Henceforth, we offer both seamless and welded pipes as well. In addition to this, we produce ERW/LSAW, and EFW pipes using stainless steel alloy. 347 Stainless Steel Pipes are available in custom lengths and sizes, you can get an idea of them using our online SS pipe weight calculator.
The 347H SS Pipes are available with different properties such as corrosion resistance ability. Stainless steel 347H is part of the precipitation-hardened steel family. Both stainless steel 347 and 347H have many of the same characteristics as each other. Other than this, many other properties are there with the pipes because of the alloying contents that are there. SS 347H is frequently used in a high stress, high corrosion settings where exposure is significant. The robustness of 347H benefits high heat production, heating coils, boiler tubes, chemical operations, and thermal maintenance. As well as checking the quality of the pipes according to the specifications of the clients, different tests are also carried out with the 347 SS Pipes. However, the tests which are performed are hardness, hydrostatic, PMI, IGC, and several others.
