Prepainted Galvanized Building Connection 0.5 Inch 2 Inch Round Tube Agriculture Greenhouse Gi Pipe

Petroleum cracking tubes: furnace tubes used in petroleum refineries. Seamless pipes for heat exchanger tubes and pipes. It is commonly used to make high-quality carbon steel (10.20), alloy steel (12CrMo, 15CrMo), heat-resistant steel (12Cr2Mo, 15Cr5Mo), stainless steel (1Cr18Ni9.1Cr18Ni9Ti). In addition to the chemical composition and various mechanical properties of the steel pipe, the water pressure must be guaranteed. Squashed. flaring and other tests, as well as surface quality and non-destructive testing. The steel pipes are delivered in a heat-treated condition.

Stainless steel pipes: hot-rolled and cold-rolled stainless steel pipes with various stainless steels, which are widely used in petroleum. In addition to ensuring the chemical composition and mechanical properties, all steel pipes used to withstand fluid pressure should be qualified for hydraulic pressure in addition to ensuring chemical composition and mechanical properties. All kinds of special steel pipes should be guaranteed according to the regulations. Welded steel pipe: also called welded pipe, it is made of steel plate or steel strip after bending and forming, and then welding. According to the form of weld, it is divided into longitudinal welded pipe and spiral welded pipe. According to the use, it is divided into general welded pipes. Galvanized welded pipe. Blowing oxygen welded pipe. Wire sleeve. Metric welded pipes. Roller tube. Deep well pump pipe. Automotive tubes. Transformer tubes. Welded thin-walled pipes. Electrically welded special-shaped pipes and spiral welded pipes. General welded pipes: General welded pipes are used to transport low-pressure fluids. With Q195A. Q215A. Q235A
