254 SMO Stainless Steel Tube Specifications

SS Tube Specification	ASTM A213, ASME SA213
OD	6 mm - 101.6 mm
Thickness	0.6 mm - 8 mm
Length	Random lengths of pipes are needed in various industrial and construction applications. There are different types of lengths available, namely Single Random, Double Random, and Required Length. Single Random lengths are random sizes ranging from 4 to 7 meters, while Double Random lengths range from 7 to 13 meters. Required Lengths are customized lengths based on specific project requirements. These options provide flexibility in choosing the most appropriate length of pipes necessary for the job.
End	Plain End, Beveled End, Treaded
Delivery Condition	Polished, Bright Annealed, Cold Drawn, and Annealed and Pickled are all different methods of processing stainless steel. Polishing involves using abrasive materials to create a smooth, shiny surface. Bright annealing involves heating the metal to a specific temperature and then letting it cool slowly, creating a bright, shiny finish. Cold drawing involves pulling the metal through a die, which can increase strength and improve surface finish. Annealing and pickling involves heating the metal to a specific temperature and then dipping it in a bath of acid to remove impurities and create a clean, uniform surface. Each of these processes can have different effects on the final product and may be chosen based on the intended use and desired properties of the stainless steel.
Packing	Our products can be packaged in various ways to meet the preferences of our customers. They can be packed in wooden boxes, bundled with steel strips, placed in plastic bags, or arranged according to specific requests from customers. We offer flexibility in packaging options to ensure customer satisfaction.

HEAT TREATMENT:

The stainless steel S31254 tube can be greatly improved in its structure and performance through heat treatment, which involves the precise control of heating and cooling processes. In the case of 254 SMO stainless steel tubes, the objective of heat treatment is primarily to alleviate stress and enhance both corrosion resistance and mechanical properties. Typically, solution annealing is the preferred heat treatment method. This process involves heating the tube to temperatures ranging from 1050°C to 1150°C, after which it is rapidly cooled (usually through water quenching or air cooling). Solution annealing has proven effective in reducing the hardness of En 1.4547 stainless steel tubes, which enhances their machinability, weldability as well as corrosion resistance.

PICKLING PROCESS:

Pickling is the immersion of 254 smo tubing in an acidic solution to remove surface oxides, dimensional out-of-conforming parts, soldering residues and other contaminants. Pickling helps improve the appearance, surface finish and corrosion resistance of stainless steel tubing. Commonly used pickling solutions include sulfuric acid, hydrochloric acid, and nitric acid. Before pickling, appropriate safety measures must be taken, and the time and temperature of pickling must be strictly controlled to avoid adverse effects on stainless steel tubes. After pickling, neutralization and flushing are usually required to ensure that no acid remains on the surface of the tube.

QUALITY ASSURANCE:

Chemical composition analysis tests 100% PMI (photoelectric emission spectroscopy).
100% hydrostatic test and eddy current test, ultrasonic flaw detection
Mechanical testing (tensile test, flattening test, hardness test, flaring test, hydraulic test)
Impact test.
Grain size test and intergranular corrosion test.
Endoscopic inspection and visual inspection for surface quality inspection
