Packing and Marking

Packed in bundles, wrapped in plastic, and suitably protected for sea -worthy delivery or as requested.

Molybdenum (Moly) increases the strength of the steel and its elastic limit, enhance the steel resistance to wear, its impact qualities, and the hardenability. It also improves the resistance to softening, makes chromium steel less prone to embrittlement and prevents pitting.

Chromium, a key element also for stainless steel alloys, prevents steel oxidation at elevated temperatures and increases the resistance of steel to corrosion. It enhances the tensile, yield, and hardness properties of low-alloy pipes at room temperatures.

Tubes with higher percentages, than standard carbon steel pipes, of alloying elements as Molybdenum (Mo), Chromium (Cr), Nickel, etc. Actually, the ASTM A335 covers low-alloy steel pipes, i.e. pipes that have a total amount of alloying elements below 5%. The addition of higher percentages of alloying elements (example Nickel and Chromium) transforms the steel into higher alloys, like stainless steel, duplex, up to super-alloyed materials like Inconel, Hastelloy, Monel, etc. ASTM A335 alloy steel pipes fit ASTM A234 WPx series buttweld fittings (WP5, WP9, WP91) and    A182 forged fittings and flanges (A182 F5, F9, F11, F22, F91). All these materials have similar chemical and mechanical properties and can be joined or welded. Alloy steel pipes are used in the energy industry for high temperature and very low-temperature service (cryogenic), or for applications with very high pressures.

Molybdenum (Moly) increases the strength of the steel and its elastic limit, enhance the steel resistance to wear, its impact qualities, and the hardenability. It also improves the resistance to softening, makes chromium steel less prone to embrittlement and prevents pitting.

Chromium, a key element also for stainless steel alloys, prevents steel oxidation at elevated temperatures and increases the resistance of steel to corrosion. It enhances the tensile, yield, and hardness properties of low-alloy pipes at room temperatures.

ASTM A213 Pipes T22 Tubes, which is also available in customized sizes, shapes and designs for our esteemed patrons. The unsuitable welding techniques for these Alloy Steel T22 Seamless Tubes Are Oxy  acetylene and submerged  arc welding, which are further well suited for diverse chemical applications. However, this kind of heat processing is not important in our Alloy Steel T22 Welded Tubes, but if followed, a complete solution annealing at 1149 Degree C or 2100 Degree F then water cooling should be done. These Alloy Steel T22 EFW Tubes with controlled composition can be employed in the welded form and it is less prone to stress corrosion cracking in the several conditions. Production of tankers from our Alloy Steel T22 ERW Tubes are used for handling hydrochloric acid, aluminum chloride catalysts and other strongly reducing chemicals, storage of reducing chemicals, manufacturing herbicides, insecticides, ethylene glycol and benzene, methyl methacrylate, butane isomerization to make high octane gasoline, prevents corrosion from antimony chloride. In reducing gases or in a vacuum, these Alloy Steel T22 Round Tubes may be used from 1600 Degree F (870 Degree C) to substantially higher temperatures. This is because, our Alloy Steel T22 Square Tubes offers resistance to an arrangement of granule margin carbide precipitates in the weld heating zones that have minimized precipitation of carbides and other forms to ensure the uniform resistance to corrosion.
