Austenitic Stainless Steel
The stainless steel pipes produced by HEE have excellent quality and large output, and can issue industry related certificates. In terms of production efficiency, we also uphold high productivity and efficiency. We have our own team of designers and provide comprehensive services in all aspects.
Our production process is clear, with dedicated personnel responsible for each process, ensuring one-on-one accountability.
Raw materials - slitting - welding and pipe making - end repair - polishing - inspection (printing) - packaging - shipment (warehousing) (decorative welded pipe)
The applications of stainless steel pipes generally include well pipes (casing, oil pipes, drill pipes, etc.), pipeline pipes, boiler pipes, mechanical structure pipes, hydraulic support pipes, gas cylinder pipes, geological pipes, chemical pipes (high-pressure fertilizer pipes, petroleum cracking pipes), and ship pipes. For example:
automotive industry
The main use of stainless steel is in the exhaust system, accounting for more than half of the total amount of stainless steel used in automobiles, with 80% being ferritic stainless steel. The exhaust gas generated by the car engine flows out of the muffler through the exhaust intake pipe, front pipe, hose, converter, and center pipe. The commonly used steel grades for exhaust systems include 409L, 436L, etc. Car mufflers mainly use stainless steel welded pipes. According to estimates, stainless steel pipes used in automobiles account for approximately 1.5% of the downstream usage of stainless steel pipes, while the ratio of seamless stainless steel pipes to welded pipes is approximately 2:1.
