• ASTM Specification for Welded Tubes (Commonly Used): ASTM A249 TP321 (Welded Austenitic Steel Boiler, Superheater, Heat Exchanger, and Condenser Tubes)

• ASTM Specification for Seamless Pipes (Commonly Used): ASTM A312 TP321 (Seamless, Welded, and Heavily Cold

Stainless steel heavy wall thickness pipes are pipes that have a thicker wall compared to standard pipes. The term "heavy wall thickness" refers to the increased thickness of the pipe's walls. This type of pipe is often used in applications where higher strength, pressure resistance, or durability is required.

The stainless steel alloy with Werkstoff Number (W.Nr.) 1.4306 is commonly known as 304L stainless steel. It is a low-carbon variation of the widely used 304 stainless steel. The "L" in 304L stands for "Low carbon," and this variant is preferred for applications where welding is required, as it minimizes carbide precipitation in the heat-affected zone during welding.

An "injection tube" could refer to a tube used in injection processes, such as in chemical or pharmaceutical industries. Stainless steel is often chosen for such applications due to its corrosion resistance and durability.

The term "IBR Approved" refers to products that comply with the requirements of the Indian Boiler Regulations (IBR). The IBR is a set of regulations that govern the design, construction, and operation of boilers and pressure vessels in India. Products approved by the IBR meet specific standards and safety criteria.

When it comes to "Stainless Steel Seamless Tube," if it is mentioned as "IBR Approved," it means that the seamless tube complies with the regulations set forth by the IBR, ensuring its suitability for use in boilers and pressure vessels in India.
