Upon the completion of the manufacturing process, CP Industries performs a variety of internal and external cleaning and preservation stages to ensure that the pressure vessel will perform acceptably in the intended application.
The exterior of a vessel is cleaned and preserved by blasting the vessel’s surface with steel grit, obtaining a near white finish. Once the service life of the pressure vessel has been determined, the application of the final protective paint system is performed. The exterior color can be matched to an exact color provided that a Federal Standard Number is provided.
Vessel interiors are steam cleaned and dried to remove all oil and contaminants, then steel grit blasted to obtain a near white finish and vacuum cleaned to remove all loose particles. Interiors are inspected to ensure cleanliness, then inerted with dry nitrogen to inhibit corrosion and sealed for shipment. Vessel interiors may be polished to a near mirror-like finish for specific applications. Specialized high purity cleaning options are available upon request. A wide range of protective internal coatings is also offered.
Pressure vessels supplied with an unpainted interior surface may be cleaned with dry nitrogen and sealed for shipment. Another cleaning option is to evacuate the vessel to an absolute pressure of three inches of mercury and pressurized (inerted) with dry nitrogen.
Also available for the interior surface is conditioning such as electropolish, passivation and special cleaning for high purity gas applications as well as internal coatings.
CP Industries has an array of outlet fittings, safety devices, valves, and miscellaneous adapters to meet the customer’s requirements. If multiple pressure vessels are required to be connected together, CP Industries can manifold the vessels in a horizontal or vertical stack.
For standard end plugs and fittings, any vessel end opening can be threaded internally with straight threads to accommodate standard plugs. Other types of end connections can be furnished upon request. CP Industries can also apply external straight threads on each vessel neck to facilitate mounting of the pressure vessels between I-Beams or steel bulkheads.
End plugs can be provided in a straight or angle configuration, in solid form or with a wide variety of threaded connections such as straight, NGT, SAE and so on. Brass shipping plugs and inerting caps are also available.
