WATER, GAS AND AIR PIPELINES

We design and supply superior quality steel pipes for various water, air and gas transport applications. Made of high quality material, these are high in performance and have found various uses in different industrial applications. These pipelines are meant for the movement of water, oil & natural gas at a very high pressure. Buried high pressure oil and gas pipelines are tested for strength by pressurizing them to at least 125% of their maximum operating pressure (MAOP).

Since many long distance transmission pipelines are designed to have a steel hoop stress of 80% of specified minimum yield (SMYS) at MAOP, this means that the steel is stressed to SMYS and above during the testing. Leak testing is performed by balancing changes in the measured pressure in the test section against the theoretical pressure changes calculated from changes in the measured temperature of the test section.
