Standard Tubular

We are the largest exporter, manufacturer and supplier of Standard Tubular in Mumbai, Maharashtra, India. Line pipe is manufactured from high-strength carbon steel, and is made to strict engineering and metallurgical specifications developed by the American Petroleum Institute (API). One particular standard, API Specification 5L, defines requirements for pipe made to transport natural gas, oil and water. This specification includes standards for the dimensional, physical, mechanical, and chemical properties of the carbon steel. Several pipe mills in North America and around the world manufacture API 5L line pipe for the natural gas industry. Pipe mills produce two types of line pipe: seamless and welded. Seamless pipe is formed from a cylindrical bar of steel that is heated to a very high temperature and then is pierced with a probe to create the hole through the cylinder. Pipe mills manufacture line pipe by forming a steel plate or coil into a cylindrical shape, and closing the seam using a welding process. The mill evaluates the quality of the weld seam using ultrasonic and/or radiological inspection methods and pressure tests each joint of pipe to levels significantly higher than the eventual operating pressure of the pipeline.
