Seamless Pipes & Tubes
We provide our clients Seamless Pipes, which are durable, corrosion resistant and find application in heat transfer process equipment like super heaters, boilers, heat exchangers and boilers. Appreciated for high tensile strength , these are used in oil & natural gas organizations, paper industry and petrochemical plants. Seamless steel pipes and tube comes in all kinds of sizes including thin, small, precise, slender and other special pipes and are used for steam boilers and pipelines, installations with high and supercritical steam conditions. These pipes and tubing are manufactured by commercial, electric furnace bearing, consumable, electrode vacuum melted quality steel. These impart strength and durability to the pipes and thus can be used for corrosion-resisting applications.
Seamless steel come in finishes such as hot rolled, cold drawn, turned, roto-rolled etc. After the end finishing, all pipes are then pressure tested on a machine. Following a final visual inspection, pipe is weighed, measured and stenciled. External coating can then be applied if required. It is involved in the applications for aircraft, missiles, anti-friction bearing, ordnance, etc.
