Shell-and-tube heat exchangers are the backbone of the power generation, chemical process, petrochemical and pulp-and-paper industries. Heat exchangers come in many types and styles, but almost all are designed as unfired pressure vessels.
At Greco Bros. Manufacturing, we produce heat exchanger complying with:
- TEMA (Tubular Exchanger Manufacturer’s Association) Heat Exchanger Standards;
- API 660, a shell-and-tube specification developed by the American Petroleum Institute;
- The HEI (Heat Exchange Institute) Standards for Shell-and-Tube Heat Exchangers; and the
- ASME (American Society of Mechanical Engineers) Boiler and Pressure Vessel Code (BPVC).
Regardless the code or specification the heat exchanger is specify to, we, at Greco Bros. will offer our customers the optimal solution for the application.
