Before EN 1092-1, Germany used DIN (Deutsches Institut für Normung) standards for flanges, such as:
DIN 2573 / 2576 (Plate flanges)
DIN 2633 / 2634 / 2635 (Welding neck flanges)
DIN 2527 (Blind flanges)
EN 1092-1 consolidates and replaces these older DIN standards while maintaining similar dimensions and pressure ratings. It ensures compatibility across Europe and with international systems.

JIS G 3452-2019 :Carbon steel pipes for ordinary piping The steel grade for our JIS G3452 Carbon Steel Pipes is SGP. This grade ensures that the pipes are of high quality, suitable for ordinary piping purposes.
Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless This specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8 to NPS 26. The steel categorized in this standard must be open-hearth, basic-oxygen or electric-furnace processed and must have the following chemical requirements: carbon, manganese, phosphorus, sulfur, copper,
Stainless steel Pipes/tubes are the most widely used due to their excellent corrosion resistance, high strength, and superior weldability. They are commonly found in oil & gas, chemical processing, pharmaceuticals, food & beverage, marine, and power plant applications.
