SKU: STC_0073068-PDF
These specifications cover the manufacture of straight seam or spiral seam electric fusion welded steel pipe, intended for the conveyance of water, which is 30 in. and greater in diameter and is in 20 ft. and longer laying length straight sections or other special sections which are required for closures, curves, changes in alignment or grade to meet special conditions. The contractor, as bidder, shall submit to the purchaser the details of the procedure he proposes to use in the fabrication of the pipe and special sections and the procedure shall comply with specifications given hereinafter. The 7A.1, 7A.2, 7A.3, 7A.5, 7A.6, and 7A.7 Committee reports are tentative specifications and are published to solicit constructive criticism from the membership as a whole. Three reports (7A.5, 7A.6, and 7A.7) have been prepared to provide protection for steel water pipe for both underground and surface requirements. However, it is recognized by this committee that in some waters and in some soils, protection to the inside and outside pipe surfaces is not necessary and this committee does not attempt to make mandatory the use of such protection or to evaluate the condition of its use. -The above paragraph is found on page 1 of the insert in the yellow covered publication, "For Use of 7A Committee Only."
