Specifications
There is no specific ASTM standard or other standard specification on fabricated fitting dimensions. However, pipe used to fabricate HDPE fabricated fittings comply with the dimensions and tolerances as specified in ASTM F714. HDPE Fabricated fittings are fabricated of pipe and plate materials consisting of virgin resin in accordance with the material specifications listed in ASTM D1248. HDPE PE3408 fabricated fittings utilize materials extruded or molded from a Type III, Class C, Category 5, Grade P-3-4 resin with a cell class of 345434C as state in ASTM D3350 and are compatible for heat fusion with any pipe manufactured from a like or similar resin.
Fabricated Fitting Pressure Ratings
Fully Pressure Rated- meets or exceeds the minimum required system design pressure. Generally, this is accomplished by utilizing pipe with a thicker wall than the adjoining pipe. It can also be accomplished by fiberglass wrapping or reinforcing the fabricated fittings.
Reduced Pressure Rated- fabricated using pipe with the same SDR as the adjoining pipe. Reduced pressure fittings are de-rated as follows: 45, 60, 67 1/2. and 90 degree elbows: 10%. Wyes and two piece tees: 25%
Please consult with the manufacturer or supplier to determine to proper pressure rating of the fabricated fitting.
