Stainless Steel Pipes

kaysuns-tubes-pipesKaysuns is a top supplier of stainless steel pipes and tubings in China, we provides both seamless stainless steel pipes and welded stainless steel tubings and other ss pipes. Austenitic stainless steel has austenite as its primary phase, our product covers full 300 series and duplex stainless steel, nickel-based alloy and super austenitic stainless steel etc. We are also ability to supply titanium alloy tube and copper alloy tubes in ASME / EN norms. All of our tubings are qualified and a third party inspection are available for them.

What Is The Technology for Seamless Stainless Steel Pipes

Cold Rolling is a preferred production process for high precision seamless stainless steel tube. Most of our heat exchanger tubes and precision tubes are cold rolled tubing. This technique provides a high forming rate, narrow tolerances and good turnouts. At present, the largest diameter we can get is 114.3mm for this processing.

Cold drawing is the common process for our ss tubings and pipes. Cold drawn stainless steel pipe will get a very narrow tolerance ranges, and keep the chemical element in a good condition. Additionally, the cold drawing process is the perfect choice for situations which place high requirements on the quality of the surface structure.

Surface Finishes:

    • Pickling finish
    • Bright annealed finish
    • Mirror/ Polished finish
    • Sand blast finish
