Product Description

ASTM A312 SS304L stainless steel seamless tube

Short Description:

ASTM A312 TP304L Stainless Steel Pipe is one of the most widely used steel pipes in the world for many reasons. The ASTM A312 Gr TP304L is cheaper than most other stainless steel products and therefore is cost effective. It is an austenitic stainless steel and has chromium content in it. This makes the ASTM A312 Grade TP304L corrosion resistant. This quality is desired in most applications. The A312 TP304L Pipe can be produced in different methods and it could come in different shapes as well. MIDAS is a large manufacturer and supplier of these pipes and we produce all kinds and variations of the product. Our A312 TP304L EFW pipes are very strong and have long lasting joints because of the electric fusion weld. We also produce electric resistant welded pipes as well.

ASTM A312 is a standard specification for seamless, welded, and heavily cold-worked austenitic stainless steel pipes. This norm covers several grades of stainless steel pipes for high-temperature and general corrosive service. It is widely used in the chemical processing, petrochemical, food processing, and pharmaceutical industries, as well as in construction and other applications.

The ASTM A312 standard covers pipes with diameters ranging from 1/8″ to 30″ and thicknesses from SCH 5S to SCH XXS. The pipes can be either seamless or welded and can be produced using several manufacturing processes, such as hot finished, cold finished, or hot rolled.

The standard requires that the pipes be made of austenitic stainless steel, which is a type of steel that contains high levels of nickel and chromium. This gives the steel excellent corrosion resistance and makes it suitable for use in harsh environments, such as those found in the chemical and petrochemical industries.

The ASTM A312 norm specifies several different grades of austenitic stainless steel, including TP304, TP304L, TP316, TP316L, TP321, TP347, and TP348. Each of these grades has specific chemical and mechanical properties that make it suitable for different applications.

In addition to the basic requirements for the manufacturing process and the materials used, the ASTM A312 norm also specifies requirements for dimensions, tolerances, and testing. For example, the norm requires that the pipes be inspected visually and that they be subjected to several types of non-destructive testing, such as ultrasonic testing and eddy current testing.

Overall, the ASTM A312 norm is an important standard in the stainless steel industry, providing guidelines for the manufacture and testing of austenitic stainless steel pipes. By ensuring that these pipes meet specific requirements for materials, manufacturing, and testing, the standard helps to ensure that they are safe and reliable for use in a wide range of applications.

Quality Control

Quality Control is one of the most important process in production. We insist that 100% inspection before shipment and ensure products without any flaws when sending out.
We have complete quality inspection facilities including mechanical testing, chemical analysis, tensile strength, hardness, spectrometer, ultrasonic testing, etc.

Products Inspection

The Inspector Checks the wall thickness of the pipe.

The Inspector Checks the OD of the pipe.

High Quality Package

1) In bundle with steel strip 

2) First packing by plastic bag then strip; Details packing please see the picture in the detial description. 

3) In bulk 

4) Client' requirements 

5) Delivery: 

• Container: 25 tons/container for pipe with usual outer diameter. For 20" container the max length is 5.85m; For 40" container the max length is 12m.
• Bulk carrier: It is no requirements to the length of the pipe. But its booking space time is long.

FAQ

Q: What is the difference between pipe design material A106 and SA106?

A: There is no difference between pipe design material A106 and SA106,
Because the 2013 edition of the ASME II material chapter has pointed out that SA106 is consistent with ASTM A106,In addition, SA106 is a grade of American ASME,And A106 is the grade of ASTM.

Q: What does the mark CD in the steel pipe SA106Gr.B standard mean?

A: CD means cold drawn,SA106 stipulates that pipes below DN40 can be hot-rolled or cold-drawn; pipes above DN50 are conventionally hot-rolled. When the manufacturer and the purchaser reach an agreement, cold-drawn manufacturing is allowed.

Q: What is the difference between ASME SA-106 and ASME SA-106M?

A: The difference between ASME SA-106 and ASME SA-106M is that if the size standard is imperial, use ASME SA-106, if the size standard is metric, use ASME SA-106M.

 

Tips: The A106 includes A106-A, A106-B and A106-C. A106 A is equivalent to the China's 10# material, and the A106 B is equivalent to the China's 20# material. It belongs to the ordinary carbon steel series and is one of the commonly used materials. ASTM A106 seamless steel pipe includes two processes of cold drawing and hot rolling. In addition to the different production processes, the two are different in accuracy, surface quality, minimum size, mechanical properties, and organizational structure. Widely used in petroleum, chemical, boiler, power station, shipbuilding, machinery manufacturing, automobile, aviation, aerospace, energy, geology, construction and military industries.
