Hydrostatic Test Hydrostatic Test or hydro test is not required for pipe fittings unless specifically requested by the purchaser. Code mandate that fittings shall be able to withstand under pressure required by applicable Piping Code. A hydrostatic test is a pressure test in which the pipe or other component is pressurized to evaluate its integrity. [...]
What is Galvanizing? Features of Galvanized Steels Steels, galvanized steels and aluminum alloys are industrially important metals that are produced in large quantities. Of these materials the corrosion protection of steel is most challenging, even if iron is nobler than zinc or aluminum. To prevent steel parts from rusting there are two options: Switch to [...]
Heat treatment of pipe depends on the way it is manufactured - hot finished or cold finished. Selection of heat treatment methods will depend on types of material and on what material properties you want to restore or further enhancement on existing properties. In the case of Hot Finished Pipe, no heat treatment is required. [...]
Introduction to Pipe Fittings Pipe Fittings are an important piping component that helps in changing the direction of the flow such as elbows, tees, changes the size of the pipe such as reducers, reducing tees, distribute the water supply from the main pipe to other pipes of equal size or lower size, etc. connect different [...]
Introduction A flange is an external or internal ridge, or rim (lip), for strength, as the flange of an iron beam such as an I-beam or a T-beam; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc., or for a flange of a rail car or tram wheel. Thus flanged wheels are wheels with a flange on one side to keep [...]
Introduction And Difference Between Seamless and Welded Pipes Seamless Steel Pipe is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. Seamless pipes are manufactured in a variety of size and schedule. However, there is a restriction on [...]
Introduction Pipes are usually produced by two distinct methods which result in either a welded pipe or a seamless pipe. In both methods, raw material is first cast into ingots. It is then made into a pipe by stretching the steel out into a seamless tube or forcing the edges together and sealing them with [...]

Carbon steel is steel with carbon content up to 2.1% by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: Steel is considered to be carbon steel when: no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium or zirconium, or any other element [...]
Difference Between Socket Weld and Butt Weld There are various connecting types for the Pipe Flanges, fittings and valves: socket weld, butt weld, threaded and so on. Two of them to be quite popular: socket welding and butt welding. However, you might be confused about which one would be best for your construction projects, since both [...]
