Gas cylinder tube is a kind of seamless steel pipe and also a kind of alloy steel pipe. It
is mainly used to make gas storage tanks, accumulators and other high pressure gas vessels.
Because of our sophisticated technology and heat treatment equipment, our gas cylinder tube
absolutely has overwhelming advantages than similar products in quality and properties, and
can be in extreme small wall thickness. the common specifications of small wall thickness tube is
273mm*6.5mm, 325mm*7mm, 356mm*7.8mm, and 406mm*9mm.
