Weld slag is defined as the crystalline residue remaining on the weld surface following a weld procedure which uses flux as a shielding method.b. POL service piping consists of piping
27、and components used for petroleum, oil and lubricants (POL) under pressure or gravity force including modifications to existing hydrant fueling systems. 1.3 SUBMITTALS*NOTE: Submittals must be limited to those necessary for adequate quality control. The importance of an item in the project should be
28、 one of the primary factors in determining if a submittal for the item should be required.A “G” following a submittal item indicates that the submittal requires Government approval. Some submittals are already marked with a “G”. Only delete an existing “G” if the submittal item is not complex and ca
29、n be reviewed through the Contractors Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in context of the project.For submittals requiring Government approval on Army projects, a code of up to three characters within the submittal tags may be used following
30、 the “G“ designation to indicate the approving authority. Codes for Army projects using the Resident Management System (RMS) are: “AE“ for Architect-Engineer; “DO“ for District Office (Engineering Division or other organization in the District Office); “AO“ for Area Office; “RO“ for Resident Office;
31、 and “PO“ for Project Office. Codes following the “G“ typically are not used for Navy projects.Submittal items not designated with a “G“ are considered as being for information only for Army projects and for Contractor Quality Control approval for Navy projects.*Government approval is required for s

37、equired has been shown and that there is no conflict between the drawings and the specifications.Project drawings must indicate, or text of project specifications must specify, the welding procedures, and size, length, type, and location of the welds, as necessary. Project drawings and/or specificat
38、ions must indicate that factory applied internal and external coatings be stopped one (1) inch from a girth weld leaving a 2“ uncoated area for welding.SECTION 33 52 90.00 20 Page 7Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-*This section covers
39、the welding of Petroleum, Oil and Lubricant (POL) Service systems. Deviations from applicable codes, approved procedures, and approved detail drawings will not be permitted without prior written approval by the Contracting Officer. Materials or components with welds made offsite will not be accepted
40、 if the welding does not conform to the requirements of this specification, unless otherwise specified. Procedures shall be developed by the Contractor for welding all metals included in the work. Welding shall not be started until welding procedures, welders, and welding operators have been qualifi
41、ed. Qualification testing shall be performed by an approved testing laboratory, or by the Contractor if approved by the Contracting Officer. Costs of such testing shall be borne by the Contractor. The Contracting Officer shall be notified at least 1 week in advance of the time and place of the tests
42、. If the Contracting Officer elects to witness the tests, the qualification tests shall be performed at or near the worksite. The Contractor shall maintain current records of the test results obtained in the welding procedure, welding operator, welder performance qualifications, and nondestructive e
43、xamination (NDE) procedures readily available at the site for examination by the Contracting Officer. The procedures for making transition welds between different materials or between plates or pipes of different wall thicknesses shall be qualified. Unless otherwise specified, the choice of welding
44、process shall be the responsibility of the Contractor.1.5 PERFORMANCE*NOTE:The paragraphs will be edited and bracketed portions inserted if necessary to ensure proper implementation of the CONTRACTOR QUALITY CONTROL PROGRAM. The specification writer or design engineer must indicate how much quality
45、control of welding is needed for each project and who is to be responsible; i.e., primarily the Contractor or the Government.In many cases a project may not require 100 percent testing of welds by NDE methods. The designer must determine the required methods and the extent of inspection and testing, and must indicate the extent in this or other sections of the project specifications or on the project drawings by notes, NDE symbols, or oth
