Stainless Steel Pipe

Kaysuns is a professional supplier of stainless steel pipe and tubing in China, we provides both stainless steel seamless pipe and stainless steel welded pipe and other ss pipes.
Our product covers full 300 series and duplex stainless steel, nickel-based alloy and super austenitic stainless steel etc, including material 304/L, 316/L, 317L, 321, 310S, 347H, 904L, 254 SMO, Duplex 2205, 2507, Monel, Inconel, Hastelloy 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.

FAQ

When you want to get a quote or place an order to us, pls clear the information:

Product + Dimension + Material + Order Quantity

For example, you want to buy 100 meters 316L stainless steel pipe, Seamless, quality to ASTM A312, 6″ SCH40S, beveled end, so the description would be:

SMLS, ASTM A312 TP316L, 6″ SCH40S, BE, 100 Meters

For the pipe quality, we will think it is ASME as they are the common grade in the market.

Please don’t hesitate to contact us if you have any question.

Yes. For the pipe we have stock, cutting length is supported. 

All of our stainless steel pipe are tracable with the contract number and heat number. For all of the stainless steel pipe and tube, we will do NDT test and PMI test before packing. 

We have more than 15 years of supplying stainless steel pipe and fittings, and serverd more than 200 clients. We are experienced to supply quality ss pipe for your project.

Absolutely, Yes.

We are experienced for third party inspection from SGS, BV, Lloyd’s, Intertek, DNV etc.

In fact, we think the inspection before shipment will reduce the disputation, it is a good way for both of us.

Why not? We can do the product based on the requirement of client, including special dimension(sometimes it will based on specific quantity). We are experiences with it, whatever the materials is stainless steel or special alloy.

For the stainless steel pipe, we commonly will pack them by waven bag and bundled by strong metal strap. For stainless steel tubing, we generally will pack them in free-fumigation wooden box. If you have special requirement, pls clarify it in the PO.

We aim the global market, including but not limited to Argentina, Belgium, Brazil, Canada, Chile, Colombia, Costa Rica, Czech Republic, Denmark, Ecuador, Finland, France, Germany, Hungary, Ireland, Italy, Japan, Kazakhstan, Korea Mexico, Netherlands, Pakistan, Panama, Paraguay, Peru , Philippines, Poland, Russia, Spain, Sweden, Switzerland, Ukraine, Ukraine, United Kingdom, United States, Uruguay, Vietnam, etc.
