Product Details

ASTM 316 / 316L Stainless Steel Seamless Pipe Tube In Standard Tube Sizes

stainless steel products include 200, 300, 400 series stainless steel plate/coil/sheet/strip/pipe. Which meet the JIS, ASTM, AS, EN, GB international supply standard conditions. There are a variety of surface treatment technologies such as 2B, BA, 8K, HL, titanium, etching, embossing, etc. Support customization, reasonable price and quality. We implement a strict quality inspection to ensure that our products are 100% qualified, and our strong logistics and transportation capabilities export our products to all over the world.

More Product Introduction

BEELING

Beveling Stainless Steel tubes contain one end angled, so that it mates with a complementary tube end. Tubes can be beveled for certain applications in order to make welding of stainless steel tubes easier, which saves weld prep time and money compared to hand cutting.

HEAT TREATING & ANNEALING

We can heat treat some 400 series stainless steel seamless tube. Heat treating realizes stress as a result of hardening, depending upon the chemistry of the metal being treated. Heat treating is also used for tempering, quenching, normalizing, and solution annealing.

HONING & TURNING

During the honing/turning process, an abrasive rotating tool removes metal from the interior surface of a cylinder, pipe, or tube. The main purpose of honing is to finish the surface to a particular diameter and/or desired cylindrical geometric design. Honing is typically a secondary machining operation that completes a produce/part, relieves stress created during production, or corrects features of the finished product. A typical production cycle is to drill, ream, heat treat, then hone.

POLISHING

POSITIVE MATERIAL IDENTIFICATION (PMI)

In some cases, it may be necessary to complete additional positive material identification testing. Kuncheng can complete this testing in house or we can work with an independent laboratory to complete the testing. Please contact us for specific requirements.

Tolerances

Hot-Finished Round Tubing Permissible Variations:

These tolerances apply to cut lengths up to an including 24 Ft. (7.3M). For lengths over 24Ft. an additional over tolerance of 1/8in (3.1mm) for each 10ft. (3m) or fraction thereof shall be permissible up to a maximum tolerance of 1/2 in. (12.7mm)

Cold-Finished Round Tubing Permissible Variations:

Tolerances of tubes produced by the rod or bar mandrel process and which have an inside diameter under 1/2 in (12.7mm) (or an inside diameter under 5/8 in. When the wall thickness is more then 20% of the outside diameter.) Are as shown in this table except that wall thickness tolerances are 10% over and under the specified wall thickness.
For Ovality values, the tolerance for average outside diameter at any one cross section does not exceed the outside diameter tolerance value for the applicable outside diameter.
Many tubes with wall thicknesses more then 25% of outside diameter or with wall thicknesses over 1 1/4 in. Or weighing more then 90lb/ft. are difficult to draw over a mandrel. Therefore the wall thickness can vary 12 1/2% over and under that specified.
For those tubes with inside diameter under 1/2 in (or under 5/8 in when the wall thickness is more then 20% of the outside diameter) which are not commonly drawn over a mandrel, A is not applicable. Therefore the wall thickness can vary 15% over and under that specified, and the inside diameter is governed by both the outside diameter and wall thickness tolerances.
These tolerances apply to cut lengths up to an including 24 ft. For lengths over 24ft, an additional over tolerance of 1/8 in. for each 10ft. or fraction thereof shall be permissible, up to a maximum tolerance of 1/2 in.
