TP347H Stainless steel seamless pipe is different with TP347 stainless steel seamless pipe.
These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements. Grade TP347HFG stainless steel seamless pipe shall be cold finished.
TP347H stainless steel seamless pipe shall be reheated to the specified solution treatment temperature for the required time before quenching.
ASTM A213 TP347H pipe are widely used in oil and chemical industry, nuclear technology, and boiler making industry.
We supply and manufacture TP347H stainless steel seamless pipe with a wide range of size, from 10.0mm to 1219mm. The wall thickness of TP347H seamless stainless steel pipe ranges from 0.5mm to 100mm. The common length of each pipe is 5.8m, 6.0m, 11.8m, 12m.
The maximum length we produce is up to 18m. Sheye Metal can produce TP347H seamless stainless steel pipes in strict accordance with ASTM, EN, JIS, DIN standard to meet client’s different requirements.
ASME SA213 TP347H pipe is the most common product. TP347H Stainless seamless pipes can be cut to size and pipe with polished finish it is also available.
A lot of processing services, including punching, painting, beveling, chamfering are all available for us. With b technical force, advanced equipment and skilled craftsmanship,
Wuxi Cepheus can manufacture TP347H pipe with good quality. For metal, we are serious.
