Seamless steel come in finishes such as hot rolled, cold drawn, turned, roto-rolled etc. After the end finishing, all pipe is 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. Ultra high strength and corrosion-resistant properties makes these perfect for oil & gas industry, chemical industry and car industry.

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 PIPE IS ALSO CALLED CDS PIPES (COLD DRAWN SEAMLESS PIPES). IT IS USED WIDELY IN MACHINING PARTS, SHAFTS, BEARINGS, CYLINDERS HAVING STRENGTH OF 75000 PSI TENSILE. IT IS A SOLID CARBON STEEL ROD WHICH IS PUSHED ON TO THE MADREL TO FORM THE SHAPE OF TUBE. IT IS AVAILABLE IN DIFFERENT SIZES.

Seamless pipe manufacturing uses hot rolled round bar billet of carbon steel or steel alloy. The billets are cut into suitable length depending on the required length of the finished tube. The billets are heated in a furnace at a temperature of 1200oC to 1300oC. Then the seamless tube is formed by drawing a solid billet over a pierce to create the hollow shell (mother blanks). These hollows are crimped at one end in hot condition and then they are air cooled.

Due to their varied uses, seamless pipes and tubes find their application in several industry sectors which include:
• Refineries & Petrochemical plants
• Fertilizer industry
• Steel plants
• Power plants
• Industry using Boilers.
• Sugar plants
• Chemical plants
• Industry using Heat Exchangers and Condensers.
• Automobile manufacturing plants
• Railways
• Defense (aircraft, missile, nuclear power plants)

We always provide the best quality of seamless tubes. Our seamless tubes can come in a plated form as well as in standard form as per our customers needs.

We have sizes from ½" to 20" NB mm stock with us..

Hi-Line Flare less Bite Type fittings are designed for use with pipes specified by their Outside Diameter or Nominal Bores and of the materials described below. In all cases, these pipes must

1. be of seamless construction
2. have precision tolerance on their Outside Diameter
3. have a blemish- free surface
4. be in a fully annealed condition with hardness not exceeding RB70

The minimum wall thickness is specified in the various standards of seamless pipes are based on the nominal working pressure, and are given below for the popular types. The fittings featured on our web site will be applicable to pipes of relevant standards on an equivalent basis.
