6 1 General Valve bodies through 100,000 psi are high tensile Type 316 stainless steel, 150,000 psi valve bodies are 17-4 PH stainless steel. Stem assemblies have non-rotating tips to prevent galling with valve seats. Packing is located below the stem threads to prevent contact with media (liquid or gas). Packing glands are equipped with locking devices or lock nuts.

elevated temperatures, any pressure rating must be stated in terms of the temperature at which it applies. Catalog listings for Parr reactors and pressure vessels show the maximum allowable working pressure at 350 C for vessels made of Type 316 stainless steel (except certain high pressure/high temperature units which are rated at 500 C).

Hydrogenation Reactor Pressure Control. Hydrogenation is a chemical reaction between a compound and hydrogen. In the fine chemicals industry, hydrogenation is commonly performed in a fixed-bed catalytic reactor. An unsaturated hydrocarbon, such as an alkene or alkyne, is reduced in the presence of hydrogen to form a saturated (or more saturated ...

Maximum operating temperature in a high-pressure reactor can reach 250 C. Heating of reactors with volumes up to 500 ml is carried out by means of a magnetic stirrer or a laboratory hotplate; for reactors with volumes from 700 ml and more a heating mantle and advanced temperature control systems are used. Effective (high-viscosity) mixing is provided by …

Pressure tests are performed to ensure the safety, reliability, and leak tightness of pressure systems. A pressure test is required for a new pressure system before use or an existing pressure system after repair or alteration. There are two methods for pressure tests: hydrostatic and pneumatic. A hydrostatic test is performed by
