Pressure Vessel Fabrication and Welding Services.

Services

Fabrication of pressure vessels

Fabrication of Pressure vessels, heat exchangers according to the ASME Code Section VIII Division 1 and Section I for boilers. MPGIA personnel is fully qualified to fabricate pressure vessels and heat exchangers in carbon steel and several alloy materials. Among the type of pressure vessels we can fabricate we can mention the following:
Process or storage tanks in several materials and alloys, shell and tube heat exchangers in several materials and alloys, U-tube and straight-tube bundle for heat exchangers in several materials and alloys, power boilers, basket strainers and coalescing filters, etc. Pig launcher and receiver packages with valves in several configurations and material specification, air cooled exchangers with finned tubes, radial flow tee fabrication.

Metal mechanic industry services

Fabrication of steel structures (load and roof), process and service pipelines, fabricated with several material specifications, such as carbon steel, hastelloy, titanium, stainless steel. Likewise, special welding application (hastelloy, Ni-Cr, Ni-Cu). Repair and maintenance of bearings boxes, transmision and mechanic seals of reactors tanks and pressure vessels. Hidrostatic testing with calibrated equipment to obtain STPS operating license (Mexico only). Thickness measurement.
We also offer elaboration and qualification of welding procedures and welders qualification in SMAW, GMAW, GTAW and FCAW processes, which includes their respective tests according to ASME Section IX, AWS D1.1 and API 1104. Machining of welding coupons for mechanic tests.
