All Reactors and Pressure Vessels are designed and manufactured with great care to assure

safe operation when used within their prescribed temperature and pressure limits.

But...the basic responsibility for safety when using this equipment rests entirely with the user;

who must:

1. Select a reactor or pressure vessel that has the capability, pressure rating, corrosion

resistance, and design features that are suitable for its intended use. Our engineers will

be glad to discuss available equipment and material options with prospective users, but

the final responsibility for selecting a reactor or pressure vessel that will perform to the

user's satisfaction in any particular reaction or test must rest with the user

In exercising the responsibility for the selection of pressure equipment, the prospective

user is often faced with the choice between over or under-designed equipment. The

hazards introduced by under-designed pressure vessels are readily apparent, but

the penalties that must be paid for over-designed apparatus are often overlooked.

Recognizing these criteria, our reactors and pressure vessels are offered in several

different styles, each designed for convenient use in daily operation within certain

temperature and pressure limits, using gaskets, closures, and other elements carefully

selected for safe operation within the limits specified for that design. But in order to

preserve the validity of these designs, all temperature and pressure limits must be

observed, and no attempt should be made to increase these limits by making alterations

substituting

2. Install and operate the equipment within a suitable barricade, if required, with appropriate

safety accessories and in full compliance with local safety codes and rules.

All standard pressure vessels are provided with either a suitable relief device or

a means to attach one (typically in the form of a plugged opening). When a pressure

vessel is delivered without a pressure venting device, it is the customer's responsibility

to provide pressure relief in order to protect the operator and the equipment from

destructive high pressures. If you need more information or need help in selecting a

proper

relief

device,

3. Establish training procedures to ensure that any person handling the equipment knows

how to use it properly.

4. Maintain the equipment in good condition and establish procedures for periodic testing to

be sure the vessel remains structurally sound.
