Welded steel gas cylinders (GB6653-86) welding gas cylinders using high-quality carbon steel material structural steel and low alloy steel.

Grade welded steel cylinders follow it with "HP" (welding bottles Pinyin initials) to show the difference. (1) The main purpose is mainly used for welding steel gas cylinders produce lower pressure cylinders, such as LPG bottles the same steel plate and steel sheet steel generally. In all aspects of products, in addition to variety steel bridge, boiler plate, automobile manufacturing steel, pressure vessel steel and multi-layer high-pressure vessel steel slabs and other purely external, some species such as automobile frames steel plate (thickness of 2.5 to 10 mm), the pattern steel plate (thickness of 2.5 to 8 mm), the variety of stainless steel plate, heat-resistant steel and other is the same sheet cross. Also, 10 steel, steel as well as the material one that Hefei steel plate are not all the same, 3mm steel, the material is not the same, the steel used by the place, not the same. 40 # steel _ exhibition of Commerce Bo (certified) _ Hefei Hefei exhibition plate by Bo Trading Company.
