Services
Air Receivers
South Gate Engineering manufactures ASME-certified air receivers that stabilize compressed air systems by storing pressurized air and reducing pulsation. These vessels ensure consistent air supply during peak demand while protecting equipment from moisture and oil buildup. Available in vertical and horizontal configurations with capacities ranging from 125 to 150 PSI, they meet industrial standards for reliability and safety.
Blowdown Tanks
Our blowdown tanks safely manage boiler discharge by reducing temperature and pressure before sewer release. Designed with tangential inlets and wear plates, these ASME-certified vessels prevent erosion while complying with local regulations. Standard models feature 3/8-inch minimum shell thickness and include safety components like pressure gauges and thermometer wells for optimal performance.
Industrial Autoclaves
Custom industrial autoclaves from South Gate Engineering provide controlled heat and pressure environments for composite manufacturing, medical waste treatment, and material testing. Built to ASME standards, these vessels incorporate safety valves and specialized linings to meet aerospace, pharmaceutical, and semiconductor industry requirements for precision processing and contamination control.
Hydropneumatic Tanks
Hydropneumatic tanks regulate water pressure in municipal and industrial systems by maintaining stable supply during demand fluctuations. Our ASME-compliant designs optimize pump efficiency and system longevity through precision-engineered storage capacity and corrosion-resistant coatings for extended service life in water treatment applications.
Refinery Equipment
We fabricate separation, conversion, and treatment vessels for petroleum refineries, including distillation columns and hydroprocessing units. These ASME-certified components withstand extreme temperatures and pressures while meeting API standards for crude oil processing, ensuring safe and efficient production of refined fuels and petrochemical feedstocks.
