These flanges are widely used in chemical processing, petrochemical, power plants, marine, and oil & gas industries due to excellent corrosion and high-temperature resistance.
Our flanges meet ASME B16.5, B16.47, and other international standards to ensure safety, quality, and performance.
Yes, we provide custom dimensions, pressure classes, and face types to meet client-specific requirements.
We export to Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, USA, Canada, and various regions in Africa.
In order to alter the physical and mechanical characteristics of metal without altering its original shape and size, we offer a variety of heat treatment services, including hydrogen heat treatment, HIC testing, blasting and painting, cutting, arc welding, epoxy cutting, PMI testing, hydro testing, NACE testing, and SSC testing. Although heat treatment is frequently linked to a metal's increased strength, it can also be used to change specific manufacturability goals, such enhancing machinability, formability, ductility, etc. The metal and heavy manufacturing sectors use our services. Customers have expressed great pleasure with our services' precision, efficacy, cost, and prompt delivery.
