It is calculated by dividing thespecified outside diameter of the pipe, in inches, by theminimum specified wall thickness, in inches. The standarddimension ratio (SDR) is a common numbering system whichis derived from

Elimination of these materials does not affect the pipelines thatare in service. They can still be used for gas distribution.

43、The main reasonfor removing these materials from this standard is to reflect the currentstate of the art in gas distribution plastic piping.4.3 Documentation A documentation system to allow fortraceability of raw materials including percentage and materialclassification (or designation, if applicabl
