  • Galvanized Steel Pipe

    Galvanized Steel Pipe

    Galvanized seamless pipe is divided into cold-plated steel seamless pipe and hot dip seamless pipe. Hot dip seamless pipe The Redu seamless pipe is to make the molten metal and iron substrate reaction, the alloy layer, so that the substrate and coating combination of both. Hot-dip galvanizing is the first steel pickling, in order to remove the steel pipe surface of iron oxide, pickling, aqueous solution of ammonium chloride or zinc chloride or ammonium chloride and zinc chloride mixed aqueous...
  • Structural Steel Pipe

    Structural Steel Pipe

    The structure steel pipe has hot – rolled seamless steel tube and welded steel tube.The seamless steel tube for structure is divided into two types according to the provisions of “seamless steel tube for structure” (GB/ t8162-2008) : hot rolling (extrusion, expansion) and cold drawing (rolling).The outer diameter of hot-rolled steel pipe is 32-630mm and the wall thickness is 2.5-75mm. The outer diameter of cold-drawn steel pipe is 5-200mm and the wall thickness is 2.5-12mm. ...
  • Black Steel Pipe

    Black Steel Pipe

    Black steel: Black iron is the uncoated steel and is also called as black steel. 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. Because black steel is subject to rust and corrosion, the factory also coats it with protective oil. Those black steel are used for manufacturing pipe and tube, which will not rust for a long time and requires very little maintenance. It is sold in standard 21-foot lengths TBE. Usages of b...
  • Boiler Pipe

    Boiler Pipe

    Boiler tubes is a one of seamless pipe. Manufacturing methods is the same as seamless tube, but it has the stringent requirements for manufacture of steel pipes. According to the temperature level,boiler tube is divided into general boiler tubes and high pressure boiler tube. Production methods: ① general boiler tube temperature is below 450 ℃, using hot-rolled pipe or cold drawn tube manufacture steel pipe. ② high-pressure boiler tube is used often in conditions of high temperature and high ...
  • Line Pipe

    Line Pipe

    Used for conveying gas, water, and oil in both and natural gas industries etc. Casing:Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore.It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place. Steel Casing Pipes have smooth wall & minimum yield strength of 35,000 psi. Tubing: Tubing ...
  • Drill Pipe

    Drill Pipe

    Drill Pipe: Drill pipe includes pipe body and tool joints(box and pin) welded together, used to connect drilling rig surface equipment and bottom equipment or bottom hole equipment. Drill pipe can bear heavy internal and external pressure, and twist, bend and vibration which can be used more than one time during oil or gas production. Drill pipes are steel tubulars fitted with threaded ends called tool joints, which are commonly used in tension in the top part of the drill string to pump flui...
