Inspection And Test
Raw Material Inspection:
1. Check the material supplier's mill test certificates
2. Check the material's quantity, size, surface condition
3. Conduct chemical analysis and mechanical property test
Process Inspection:
1. Inspect single work-piece's dimension, levelness, bend
degree, hole size, hole location, etc.
2. Inspect the work-piece's welding result
Cleaning Result Inspection:
After the work piece pass the process inspection, then go to cleaning to wipe out its oil&grease, dust, and other contaminants. Inspection method:
1. Visual inspection
2. Wipe test
3. Black light test
4. Mirror test (if need)
Assembly Inspection:
After cleaning inspection is good, then assemble on set to inspect its overall levelness, dimension, etc.Water Test:
Water test is a good way to check the distributor's working performance. The test items includes:
1. Liquid height in trough
2. Used time of one hole to fill the container
3. Calculate the coefficient variance(CV)
Package Inspection:
1. Check the small parts quantity according to packing list

Product Description:
Stainless Steel pipe (Stainless Steel) is a hollow strip of cylindrical Steel, his scope of application as the pipeline of fluid transport, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. Stainless steel pipes are made of acid and heat resistant billets, heated, perforated, sized, hot rolled and cut.
Classification of stainless steel pipe: stainless steel seamless steel pipe and stainless steel welded steel pipe (seam steel pipe) basic two categories. According to the outer diameter shape of steel tube can be divided into round tube and special-shaped tube, what is widely used is circular steel tube, but also have a few square, rectangle, semicircle, hexagonal, equilateral triangle, octagonal special-shaped steel tube.

Value-added services
BEVELING
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
Permanent Steel 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. Permanent Steel can complete this testing in house or we can work with an independent laboratory to complete the testing. Please contact us for specific requirements.
UT TESTING
Ultrasonic Testing (UT) utilizes sound energy at high frequencies, in order to provide examinations and measurements of the stainless steel product. This aids in flaw detection/evaluation, dimensional measurements, etc.B:Stainless steel welded pipe:

Ultrasonic Testing (UT) utilizes sound energy at high frequencies, in order to provide examinations and measurements of the stainless steel product. This aids in flaw detection/evaluation, dimensional measurements, etc.B:Stainless steel welded pipe:

Manufacturing process:
Stainless steel welded tube is a steel pipe made of steel plate or strip steel that is crimped and formed by a unit and a mold. The production process of welded steel pipe is simple, the production efficiency is high, the variety and specification are many, and the equipment investment is small, but the general strength is lower than that of seamless steel pipe.
