LSAW Steel Pipe Galvanized ERW Steel Pipe

ASTM A53 Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless. BS 7 Standard Specification for Screwed and socketed steel tubes and tubulars and for plain end steel tubes suitable for welding or for screwing to BS 21 pipe threads. ASTM A123 Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products * Difference between black steel pipe and galvanized steel Black steel pipe is the uncoated steel and is also called as black steel. The dark color comes from the iron-oxide formed on its surface during manufacturing. When steel pipe is forged, a black oxide scale forms on its surface to give it the finish which is seen on this type of pipe. Galvanized steel pipe is that steel that has been covered with a layer of zinc metal.

Black pipe is made of steel as is galvanized pipe. The difference is that galvanized pipe is coated with zinc, while black pipe is not. 2. Black pipe is best used for gas lines, not for water lines because it rusts easily, while galvanized pipe is the safer pipe to use in water lines, but it cannot be used to convey gas. 3. Difference between black steel pipe and carbon steel pipeThat is if you are talking about general welding and not for some specific application like very cold temperatures. Black steel pipe is not really a specification but rather a generic term used primarily by plumbers to distinguish regular steel pipe from galvanized steel pipe. Most black steel pipe has a composition similar to ASTM A-53 pipe. The difference between A-53 and common steel pipe like A-106 are so close that some pipe galvanized steel water pipe specifications - The galvanized steel water pipe specifications you can find on the site are generally built using hot-dipped technology to prevent rusting and weakening of the structural elements. With seamless welding quality, these galvanized steel water pipe specifications are annealed with nitrogen protection and are polished with utter professionalism. These products are made of robust materials such as carbon steel, stainless steel, galvanized surface-treated iron What is Galvanized Steel Pipe?Galvanized steel pipe is covered with a zinc material to make the steel pipe more resistant to corrosion. History of Galvanized Steel Pipe The process of galvanization was first discussed by scientists in the 1770s, nearly 60 years before it was finally introduced in the 1830s.

ERW(Electric Resistance Welding) pipe used for transmission of oil, natural gas and other fluid medium which is suitable for high or low pressure purpose. Black steel pipe is made of steel that has not been galvanized. Its name comes from the scaly, dark-colored iron oxide coating on its surface.
