Molded Fitting Specifications
Molded Butt
Fittings-All molded
fittings are designed to be fully pressure rated to the equivalent SDR
in HDPE pipe.
Molded butt fusion fittings are manufactured in compliance with ASTM D3261 (Standard Specifications For Butt Fusion Polyethylene Fittings). Measurement is done in accordance with ASTM D2122.
Our molded butt fittings fully comply with the requirements of ASTM D2513 and API 15LE. Molded butt fusion fittings are molded from pre-blended virgin resins in accordance with the material specifications listed in ASTM D1248.
Molded Socket
Fittings-Molded
socket fusion fittings are designed with a wall thickness sufficient to
qualify as a SDR 7 and exceed the maximum requirements for SDR HDPE pipe.
Molded socket fusion fittings are manufactured in compliance with ASTM D2683 (Standard Specifications For Socket Type Polyethylene Fittings).Measurement is done in accordance with ASTM D2122. Our socket fusion fittings fully comply with ASTM D2513 and APE 15LE.
| Fabricated Fittings-
HDPE Fabricated Fitting 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. |
