We design ASME pressure vessels and heat exchangers and offer full fabrication services. Our pressure vessels are used in various industries such as power generation, oil & gas, marine offshore, building & construction, locomotive, automobile, pharmaceutical and air-conditioning industries.

Our products include Shell Tube Heat Exchanger, tube bundle, air coolers, pressure water tanks and Steam Condenser. We offer electric & steam water heaters, charge air coolers and oil cooler/heaters.

Shell Tube Heat Exchangers:

Shell Tube Heat Exchanger is applied in marine, refinery, power plant and chemical industries. It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed by several types of tubes such as plain and longitudinally finned. The shell material is made using carbon steel and stainless steel. Tube material of shell tube heat exchanger is made using different types of raw materials such as aluminum, brass, copper and stainless steel. Tube plate material utilizes copper and stainless steel. Baffle plate material utilizes carbon steel and stainless steel. Our products are widely used in space heating, refrigeration, air conditioning, power plants, chemical plants, petrochemical plants, petroleum refineries, natural gas processing, and sewage treatment.

Air Cooler:

We specialize in Charge Air Cooler servicing, repair & new fabrication. Tube materials are made in alumiunum brass copper, stainless steel or Ti. Our capabilities include:

• Ultrasonic Cleaning
