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.  
 

For the steel pipe under fluid pressure to carry out hydraulic test and ray flaw detection to test its pressure ability and quality, under the specified pressure does not leak, wet or expansion for qualified, some steel pipe according to the standard or the requirements of the side test, flaring test, flattening test.

Ferritic and Martensitic Steel

TP405 Used for applications where hardening upon cooling from high temperatures must be avoided. Has excellent
long-time stability up to 1200°F.
TP410 General purpose grade for use in mildly corrosive environments
TP430 Mechanical & structural tubing, Architectural tubing, Heat exchanger tubing, Condensers, Re-heaters, Evaporators.

S32750 Used in oil & gas, chemical process, power industries. At that heat-exchangers are main application.
S31254 With high levels of chromium, molybdenum, and nitrogen is especially suited for high-chloride environments such as brackish water, seawater and other high-chloride process streams.

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.

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.
