Standard Chemical Maintenance

Concept Design Criteria for Standard Chemical Maintenance Facility...

The total estimated cost for tailored standard chemical maintenance facilities constructed at each installation is 193,700,000 with one explosive wing at Anniston or 204,700,000 for two explosive wings at Anniston. 

With limited facilities currently available for chemical maintenance, the DARCOM Ammunition Center, Savanna, IL, at the direction of the US Army Materiel Development and Readiness Command, was tasked to develop a concept design for a Standard Maintenance Facility for Toxic Chemical Munitions. 

ASTM. American Society for Testing and Materials produces the largest single source of standards, consisting of nearly 70 volumes divided by subject matter into 16 sections. The most commonly used ASTM standards in the process industry are available in a compendium, ASTM Standards for Maintenance Repair and Operations Materials in the Chemical Process Industry. ASTM uses letter-number designations to describe its standards. See Figure 2-2. 

Corrosion. Anticorrosion measures have become standard ia pipeline desiga, coastmctioa, and maintenance ia the oil and gas iadustries the principal measures are appHcation of corrosion-preventive coatings and cathodic protection for exterior protection and chemical additives for iaterior protectioa. Pipe for pipelines may be bought with a variety of coatiags, such as tar, fiber glass, felt and heavy paper, epoxy, polyethylene, etc, either pre-apphed or coated and wrapped on the job with special machines as the pipe is lowered iato the treach. An electric detector is used to determine if a coatiag gap (hoHday) exists bare spots are coated before the pipe is laid (see Corrosion and corrosion control). 

Introduction Review and audit processes are used in the chemical process industry to evaluate, examine, and verify the design of process equipment, operating procedures, and management systems. These processes assure compliance with company standards and guidelines as well as government regulations. Reviews and audits can encompass the areas of process and personnel safety, environmental and industrial hygiene protection, quality assurance, maintenance procedures, and so on. 

The nuclear equipment failure rate database has not changed markedly since the RSS and chemical process data contains information for non-chemical process equipment in a more benign environment. Uncertainty in the database results from the statistical sample, heterogeneity, incompleteness, and unrepresentative environment, operation, and maintenance. Some PSA.s use extensive studies of plant-specific data to augment the generic database by Bayesian methods and others do not. No standard guidance is available for when to use which and the improvement in accuracy that is achieved thereby. Improvements in the database and in the treatment of data requires, uhstaiui.il indu.sinal support but it is expensive.
