Cast iron pipe

Cast iron (Cast Iron Pipe), the casting of cast iron pipes. Cast iron pipe for water supply, drainage and gas pipelines, including cast iron pipe and pipe fittings.

According to different casting methods, divided into continuous cast iron pipe and centrifugal casting iron pipe, in which centrifugal casting iron pipe can be divided into two types: sand and metal. By different divided into gray cast iron and ductile iron pipe.

Seamless steel pipe

Seamless hollow sections, large pipes used as transmission fluid, such as oil, natural gas, coal gas, water, some solid material piping and so on. Pipe and round, solid steel compared, in anti-bent anti-twist strength phase while, weight more light, is a economic section steel, widely for manufacturing structure pieces and mechanical parts, as: oil drill pipe, and car drive shaft, and bike frame and building construction in the with of steel scaffolding, with pipe manufacturing ring parts, can improve material utilization, simplified manufacturing process, save material and processing work, has widely with pipe to manufacturing.

Galvanized steel pipe

Hot dip galvanized steel surfaces plated or zinc plating welded steel tubes. Galvanized steel pipe to increase corrosion resistance and prolong service life. Galvanized pipe is widely used, with the exception of water, gas, oil pipelines and other generally low fluid pressure tubes, also for the oil industry, especially in the offshore oil field of OCTG, oil pipelines, chemical coking oil heaters, coolers, coal distillation of wash oil exchanger tubes and bridge piles, mine tunnels support frame tubes.
