Section 255.281 - Plastic pipe

(a) A plastic pipe joint that is joined by solvent cement, adhesive or heat fusion may not be disturbed until it has properly set.

(b) Plastic pipe may not be joined by a threaded joint or miter joint.

(c) The quality of the joints shall be checked visually. If there is any reason to believe the joint is defective, it shall be removed and replaced.

(d) Each solvent cement joint on plastic pipe must comply with the following criteria:

(1) The mating surfaces of the joint must be clean, dry, and free of material which might be detrimental to the joint.

(2) The solvent cement must conform to ASTM Specification D2513 (as described in section 10.3 of this Title).

(3) The safety requirements of Appendix A of ASTM Specification D2513 (as described in section 10.3 of this Title) must be met.

(4) The joint may not be heated to accelerate the setting of the cement.

(e) Each heat-fusion joint on plastic pipe must comply with the following criteria:

(1) A butt heat-fusion joint must be joined by a device that holds the heater element square to the ends of the piping, compresses the heated ends together, and holds the piping in proper alignment while the plastic hardens.

(2) A socket heat-fusion joint must be joined by a device that heats the mating surfaces of the joint uniformly and simultaneously to essentially the same temperature.

(3) An electrofusion joint must be joined utilizing the equipment and techniques of the fittings manufacturer or equipment and techniques shown, by testing joints to the requirements of section 255.283(a)(1)(iii) of this Part, to be at least equivalent to those of the fitting manufacturers.

(4) Heat may not be applied with a torch or other open flame.

(f) Each adhesive joint on plastic pipe must comply with the following criteria:

(1) The adhesive must conform to ASTM Specification D2517 (as described in section 10.3 of this Title).

(2) The materials and adhesive must be compatible with each other.

(g) Each compression type mechanical joint on plastic pipe must comply with the following criteria:

(1) The gasket material in the coupling must be compatible with the plastic.

(2) A rigid internal tubular stiffener, other than a split tubular stiffener, must be used in conjunction with the coupling.
