What is SDR 26 pipe used for?

Used for non-pressure drainage of sewer and surface water where extra heavy wall SDR 26 is specified. Our gasketed sewer pipe has a specially designed Double Seal Locked-In gasket that provides a leak-proof joint on extremely durable pipe.

What color is SDR 26?

SDR 26 PVC Grip Joint Pressure Pipe in Green.

Will schedule 40 fittings fit SDR 21 pipe?

Re: Do sch 40 pvc fittings fit SDR 21 pipe? Usually SDR has a 4″ i.d., the same as sch 40, but since the wall is thinner the o.d. is NOT the same. There are glue on bushings to increase the size so it will fit in standard fittings.

Is SDR 26 pipe pressure rated?

Pressure PVC Pipe conforms to ASTM D2241 for standard dimension ratios and is available in SDR 64 (63 psi) SDR 41 (100 psi), SDR 32.5 (125 psi), SDR 26 (160 psi), SDR 21 (200 psi) and SDR 17 (250 psi).

Is SDR 26 the same as Schedule 40?


What does SDR 26 mean?

“Standard Dimension Ratio” – SDR – The ratio of pipe diameter to wall thickness (SDR = D / s) D = pipe outside diameter (mm, in) s = pipe wall thickness (mm, in) SDR 26 (Diameter – D – is 26 times the wall thickness – s ) Thus rated pressure is higher for low SDR ratios and lowwer for higher SDR ratios.

What is the difference between Schedule 40 and SDR 35?

SDR will bend with the shifting and settling. Having a higher flex tolerance means less breaks from the soil conditions. Schedule 40 is so rigid that in the event the ground shifts or settles this pipe has no give. It will simply snap or break from the pressure.

Is SDR the same as Dr?

The terms “dimension ratio” and “standard dimension ratio” are widely used in the PVC pipe industry. Even though the terms DR and SDR are synonymous, one minor difference between them is that SDR refers only to a particular series of numbers, i.e., 51, 41, 32.5, 26, 21, etc. …
