8、Pipes Introduction This Standard is the Japanese Industrial Standard prepared based on IS0 2531 Ductile iron pipes, fittings, .accessories and their joints for water or gas applications, published in 1998 as the fifth edition, in such a manner that the corresponding parts in the corresponding Intern
9、ational Standard are contained without modifying the technical content. 1 Scope This Japanese Industrial Standard specifies the ductile iron pipes (hereafter referred to as “pipes”) used for carrying water and the like, under pressure or non-pressure, through the pipes buried underground or laid on
10、the ground. The pipes are manufactured by dissolving the appropriate raw materials to ductile iron, carrying out the optimum treatment for spheroidizing of graphite as cast, pouring into the mould and applying the centrifugal force. Further, if necessary, the pipes shall be heat-treated for annealin
11、g and the like. Remarks : The corresponding International Standard is as follows : IS0 2531 : 1998 Ductile iron pipes, fittings, accessories and their joints for water or gas applications. 2 Normative references The following standards contain provisions which, through reference in this Standard, co
12、nstitute provisions of this Standard. The most recent editions of the standards indicated below shall be applied.

40、out for all products by visual observation as follows: The pipe shall be practically straight, its inside and outside periphery shall form concentric circles, and both ends shall be at right angles to the axis. In case of doubt, the pipe shall be rolled on two supports or rotated along its axis on r

In this case, pipe shall be straight with a maximum deviation of not more than 0.125 % of their effective length. The inside and outside su
42、rfaces of the pipe shall be free from blowholes or other defects that are detrimental to practical use. Slight flaws and the like, however, may be repaired by welding or with a resin filler. Coating and Lining The pipes shall be coated and made lining as follows : The coating materials shall not con
43、tain the harmful components for use, be insoluble in water after drying and show no irregularities by heat and cold. When the inside surfaces of the pipe are coated by Epoxy -powder coating, it shall be in accordance with JIS G 5528, and, in the case of applying a mortar lining treatment, it shall b
44、e in accordance with JIS A 5314. However, by the agreement between the purchaser and the supplier, other kinds of coating or lining may be employed. The exterior of pipes, unless otherwise specified, shall be coated with epoxy, acrylic synthetic resin paint and the like. However, by the agreement be
45、tween the purchaser and the supplier, other kinds of coating or lining may be employed. Zinc primer may be used as an under coating for the exterior of pipes.
