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

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.

Available in different specifications, these U bend tubes can be custom designed in various diameters as per the requirements of our clients.

Features :

• 'U' bending is done by cold working process.
• 'U' bending is done to the required radius as per customer drawings.
• The bend portion and six inch leg is stress relieved by resistance heating.
• Inert gas (Argon) is passed through it at the required flow rate to avoid oxidation in ID.
• The radius is checked for its OD and wall thinning with the recommended specification.
• The physical properties and micro-structure is checked at three different position.
• Visual inspection for waviness and cracks is done with Dye Penetrant Test.
• Each tube is then hydro tested at the recommended pressure to check for leakage.
• Cotton ball test is done to check the ID cleanliness of the tube.
• Thereafter pickled, dried, marked and packed.
