Long Radius Bend

Commercially available natural grades are made resistant to extreme oxidation, impartial and hindered decreasing conditions, as well as moderately decreasing environments, thanks to long radius bend pipe fittings. Heavy corrosion may also be caused by strong reducing media.Aluminum and its alloys are among our most adaptable engineering and building materials due to a precise combination of characteristics. Although they are light in weight, some of them offer more strength than structural steel. Most alloys have very long service lives below most carrier conditions, and no colored salts are designed to discolor or stain adjacent surfaces or things they come into touch with, such as textiles in the textile industry and chemical equipment solutions.

The long radius bend pipe fittings made of alloy steel have high reflectivity to both heat and light, as well as appropriate thermal and electric conductivities. It is easily shaped into any shape and can accommodate a wide variety of floor finishes with ease.Due to the advanced properties of the alloy, they are the perfect product for a wide range of home, commercial, and commercial applications. Apart from its well-known conventional attributes, such as malleability, resistance to corrosion, and electric and thermal conductivity, copper exhibits significantly higher flexibility when combining with other metals to provide the overall performance traits required to meet the progressively complex demands of modern society.

Our products have won approvals of major end users in India and overseas including oil and gas, power station, petrochemicals and shipbuilding industries.
