ASTM A249 SMO 254 ERW Tubing Stockist and Supplier in Mumbai India.


SMO 254 is an alloy that consists of high amount of molybdenum, copper, and nitrogen. The alloy is mainly developed with a series of other alloys that can resist stress corrosion cracking. The alloy can also be fabricated and welded in any form. However, this alloy is widely used in industries for manufacturing products like SMO 254 Tubes. These tubes are considered suitable for transporting liquids and can easily withstand in high and elevated temperature. The alloy can also be forged at a temperature up to 1920 degree F and is heat-treated at a temperature up to 1150 degree C.


Preston pipes and alloys are the reputed dealers, supplier, and exporter of tubes. These tubes are considered suitable for all kinds of application that are used especially at high temperature. Being the reputed trader of tubes we make sure that all our products are supplied to customers as per their requirement and demand. Not only this, we even ensure that these tubes are produced using high and top-notch quality of raw material purchased by the reputed market vendors.


These tubes are also known best for their excellent admirable features like excellent surface finishing, superior quality, durability, weldability, and long functional life. These tubes can even withstand high temperature and pressure without getting damage or rust. However, to ensure the quality and performance of these tubes, there are few tests conducted that are done by our hired team of quality inspectors. The tests include third-party inspection, hardness test, visual inspection, destructive and non-destructive test, positive material identification test and radiography test.


The entire testing process takes place under the supervision of experts as per the rules and regulations set by the industry. When we are sure that our products are of high quality and standards, we make sure that the SMO 254 Tubes are packed in the high quality of packaging material so that they won’t get damaged until they reach their respective customers.
