Reactors can be  built in accordance with Section VIII Division 1 or Division 2 of the ASME Code, and are stamped and registered with the National Board. As a policy, only the the most advanced welding procedures and methods are used.

Dimple Jackets are best  utilized for moderate heating and cooling utilizing steam or chilled water. RAS's innovative dimpled stayed jacket design, permits thinner vessel wall construction using lighter gauge materials.

Nickel Alloy Jackets are recommended when the heat transfer medium contains chlorides or other stress corrosion cracking elements. Jackets can be configured as either singe or multi-zoned

Half Pipe Coils are best suited for high temperature and pressure applications utilizing hot oil or other  high temperature media. RAS half pipe coil design is a full 180º half pipe configuration that minimizes pressure and increases fluid velocity.
