Flange


MSA metallurgy production group employing first-rate services of forging equipment such as hydraulic hammers, presses, ring  rolling  machines  and research and laboratory facilities is one of the greatest manufacturers of high pressure flanges used in oil and gas industries and low pressure water flanges as per the latest universally acknowledged standards.

Also, this group which has advanced equipment in steel melting/making workshops including vacuum melt filtration convertor can produce a variety of carbon, stainless, alloy steels with high strength and resistance to corrosion in sour environments containing H2S in different conditions and requirements on the basis of NACE MR0175/IS015156 standard (HIC, SSCC-resistant) for the production of flanges with forging method.

Moreover, the flanges produced in metallurgy production group are brought under different heat treatment processes such as normalizing, annealing, quenching and tempering to meet the mechanical properties of the desired standards.
