The Stainless Steel Seamless Pipes offered by us are appreciated for various features such as durability, fine finishing, corrosion resistance and dimensional accuracy. The seamless pipes manufacturing process includes the formation of mother tube with the help of premium quality stainless steel strips. The pipes further, goes through cut-off, hydrostatic testing, annealing, straightening and pickling. These pipes are then tested on different quality parameters and marked with company logo. The product is packed flawlessly and delivered to the client.

Specification

We manufacture a range of high quality Stainless Steel Welded Tubes, that are used in various industrial applications. The cold rolled stainless steel strips are welded into tubes in the state of the art tube mills under fully automated precision process. Complying with the international standards, these can be availed in various sizes and specifications to suit the diverse requirements of the clients.

The manufacturing of tubes begins with slitting of strips of required width based on the diameter of the tubes to be formed. Stainless steel slitted strips are passed through a series of rollers and tubes are formed automatically on different stands with rolls and welded on fully automated process of TIG welding without the addition of filler metal.

The welding head line is polished continuously with the help of automatic bead polishing machine to produce a perfect bore. The tubes are then passed through a series of sizing rolls to ensure ovality and tolerances. Tubes are then cut to length, cold-drawn, solution annealed, straightened, pickled, passivated and polished before other destructive and non-destructive testing & dispatch.

We offer the following :

• Instrumentation Tubes, Heat exchanger Tubes and General Engineering Tubes that are available in 10.00 mm to 114.30 mm OD sizes
• Automobile exhaust Tubes are available in 20.00 mm to 88.90 mm OD sizes range
• Welded Pipes are provided in 1/8" to 24" NB sizes

The tubes are mainly manufactured for following industries :

• Heat Exchangers
• Instrumentation Tubes
• General Engineering
• Automotive Industry

Our range of Carbon/Alloy Steel Seamless Pipes, Carbon Steel Welded Pipes, API 5L Grade B Pipe are widely acclaimed for their features such as high tensile strength, smooth internal finish and hardness. Designed with precision, these pipes are ideal for marine applications, nuclear power and fossil fuel power plants, transportation, petroleum plants and construction. These seamless alloy/carbon steel pipes, carbon welded pipes are generally developed for energy-related applications involving oil and gas drilling. Further, our range of steel alloy/carbon steel pipes can be availed in different material and dimensional specifications as per specific application .

Specifications :

We are a leading name in successfully handling the requirements of Alloy Steel Seamless Pipes and Alloy Seamless Pipes. Other than carbon, these contain in them substantial quantities of nickel, manganese, chromium, silicon, tungsten, vanadium, molybdenum. Further, these are also added with limited amounts of elements like sulphur, silicon, manganese and phosphorous that helps in increasing

• Hardness of pipes
• Strength of pipes
• Chemical resistance of pipes

With the pipes manufactured at par with international standards, we have with us necessary support of latest equipment that helps us in developing process knowhow as well as sound production practices that are second to none. Following well defined and stringent de-oxidation practice for ensuring macro inclusions are floated out from molten metal. Some of the other safeguards taken by us during production so as to achieve quality steel include:

Ensuring slag in LRF is quickly synthesized
Ensuring low re-oxidation at caster by controlling superheat
As quality of inputs used has direct bearing on quality of output only chosen mix of virgin metal and clean scrap is melted so as to control appearance of tramp elements For ensuring quality in the raw materials used, we work with trusted suppliers who are periodically audited so as to ensure materials adherence to defined industry standards

Application Usage :

Alloy steel pipes are known to deliver exceptional performance and are generally developed for meeting the demands of

• Energy-related applications that involve Oil and Gas Drilling
• Catering to domestic or industrial needs
• In conveyance of fluids intended for critical high temperatures
• In general corrosion service applications
• In heat transfer process equipment like Boilers, Heat Exchangers
• In General Engineering and Process Instrumentation applications
