HP295 Welded Gas Cylinders Steel Plate

Gnee Steel (Tianjin) Co., Ltd. is one of the most professional hp295 welded gas cylinders steel plate manufacturers and suppliers in China. Welcome to wholesale customized hp295 welded gas cylinders steel plate at competitive price from our factory. Good service and quality products are available.

 

HP295 welded gas cylinders steel plate is a specialized hot-rolled carbon structural steel designed exclusively for welded gas cylinder production.

 

The grade "HP" stands for "Huan Ping (Welded Cylinder)" in Chinese pinyin, representing its professional application in gas cylinder manufacturing. This steel grade is formulated to meet the strict safety and performance requirements of high-pressure gas storage and transportation, with balanced strength, toughness and ductility to ensure long-term safe operation of gas cylinders under pressure.

 

Our HP295 steel plate is produced in strict accordance with GB/T 6653 standard, adopting advanced smelting, rolling and heat treatment processes to guarantee uniform internal structure, stable chemical composition and consistent mechanical properties. It is widely used for manufacturing LPG cylinders, industrial gas cylinders, acetylene cylinders, compressed gas cylinders and other small and medium-sized welded pressure vessels.

 

GNEE is a trusted manufacturer and supplier of high-quality pressure vessel steel plates, specializing in producing HP295 steel plates fully compliant with GB/T 6653 standard.

 

Our HP295 gas cylinder steel plate features stable mechanical properties, excellent weldability, outstanding stamping formability and reliable pressure resistance, making it the ideal raw material for manufacturing various welded gas cylinders, pressure vessels and related gas storage equipment.

 

• Executive Standard: GB/T 6653 (Steel Plates for Welded Gas Cylinders)
• Steel Grade: HP295
• Application Scope: Hot-rolled steel plates with thickness 2.5mm-12.0mm and cold-rolled steel plates with thickness 1.5mm-4.0mm for welded gas cylinders
• Equivalent Grades: Closely matched with JIS G3116 SG295, suitable for international gas cylinder manufacturing projects
