Steel Pipes manufactures and Exports huge range of ERW Galvanized Steel Pipes. For pipes or tubes size 4 inch (10.2mm) OD and below, strip is fed into a set of forming rolls which consists of horizontal and vertical rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding electrodes. The electrodes are copper disks connected to the secondary of a revolving transformer assembly. The copper disk electrodes make contact on each side of the seam and temperature is raised to the welding point. Outside flash is removed by a cutting tool as the tube leaves the electrodes, inside flash is removed either by an air hammer or by passing a mandnel through the welded tube after the tube has been cooled. This is termed as Electric Resistance Welded or ERW tube/pipe.

ERW pipes are used in Water Pipelines, Agriculture and Irrigation (Water Mains, Sewerage Systems, Industrial Water Lines, Plant Piping, Deep Tube-Wells & Casing Pipes). Other popular application area includes usage in gas pipe lines (pipe lines for natural gas, LPG and other non-toxic gases). The SW is meant for shallow water applications This could be in a canal, natural stream, culvert, or pipe.

ERW Galvanized Pipes & Tubes has long been one of the most used building materials in the world. For decades, designers, builders & consumers seeking long term structural performance, in the tuff outdoor applications, have turned to zinc coated steel pipes. ERW Galvanized Pipes resist the attack of wild, water & road salts.

ERW Galvanized Steel if the one, that’s been covered with a layer of zinc metal. During galvanizing, steel is immersed in a molten zinc bath, ensuring a tough, uniform barrier coating. Zinc’s natural corrosion resistance provides long-term protection, even in outdoor environments.

Apart from preventing water corrosion, it is equally effective in dry & indoor environments also.

ERW Galvanized pipe is steel pipe covered with a protective coating of zinc that greatly reduces its tendency to corrode and extends its life expectancy.
It may be used in residential water supply lines, but not gas lines because natural gas causes the zinc to flake off and clog the system.
It's not frequently used for water supply lines because the minerals in the water react with the galvanizing material and form scale, which builds up over time and will eventually clog the pipe.
ERW Galvanized pipe was commonly used for water supply lines many years ago, but over time many have filled with scale, which is why some older homes suffer from low water pressure. Hard water greatly reduces the life of steel pipe.
While it can be used for all piping inside a building, its most popular use today is for handrails or for replacement of existing pipe. Copper pipe and plastic are preferred for underground installation.
Fittings for this type of pipe are of galvanized malleable (soft) cast iron. They connect by screwing onto the threaded pipe, after applying a small amount of pipe joint compound on the threads. Larger diameter pipe is welded rather than threaded. Galvanized pipe is cut either with a heavy-duty tube cutter or cutoff saw, or by hacksaw
It is sold in the same standard 21-foot lengths. Connectors and fittings are screwed onto the pipe, after applying a small amount of pipe joint compound onto the pipe threads. It is cut either with a heavy-duty tube cutter or cutoff saw, or by hacksaw.
