SANI-21 ASTM D3034

Sani-21 SDR35/26

Diamond Plastics manufactures 4” through 60” solid-wall PVC sewer pipe in accordance with ASTM D3034, Standard Specification for Type PSM Poly(vinyl Chloride) (PVC) Sewer Pipe and Fittings.

This standard contains manufacturing and quality control requirements for gasketed PVC sewer pipe. 4” through 15” sizes are manufactured with SDR’s of 35 and 26, regardless of pipe diameter. 18” through 60” sizes are manufactured with pipe stiffnesses of either 28 psi, 46 psi, 75 psi, or 115 psi, regardless of pipe diameter (equivalent to SDR’s 41, 35, 32.5, or 26, respectively).

ASTM D3034 was originally published in 1972 and included sizes 4” through 15”. In 1980, ASTM F679 was published and covered large diameter PVC sewer (18” sizes larger). In 2024, ASTM D3034 and ASTM F679 were merged, with all sizes being included in ASTM D3034.

These products have become the standard for sanitary sewer applications over the last 40 years. PVC solid wall sewer products manufactured to ASTM D3034 have bottle tight joints, corrosion free materials, superior hydraulics, strength, and flexibility.

These products are also suitable for most low-head gravity flow applications where bottle tight joints and corrosion free materials are desirable.
