Standard Practice for Field Leak Testing of Polyethylene

5.5 Expansion Allowance— When test pressure is applied, polyethylene or crosslinked polyethylene pipe will expand slightly due to elasticity and Poisson effects. To compensate for expansion, make-up water is added during the initial expansion phase. The amount of make-up water (expansion allowance) will vary because expansion is not linear.

Introduction Deflection Testing

ASTM F1417 entails testing a run of pipe from one manhole to the next adjacent manhole. Inflatable plugs are positioned into the manholes and secured. Air is introduced into the pipe line and gradually builds pressure. Once the line has been pressurized and is stable at 4.0-psi, the pressure is decreased to 3.5-psi at which time the line must not

PRESSURE DROP EXPECTED WHEN PRESSURE TESTING

Jan 30, 2009· testing HDPE pipe has some unique challenges. Mainly from the fact that the pipe will stretch which lowers the pressure. When we test, we pressurize the pipe to 120 lbs, hold for a hour. The pressure always drops as the pipe expands. Then we drop the pressure to 30 - 40 lbs. Then we watch the pressure over the next hour.

What is pipe test ? Testing methods, strength and resistance

The determination of the required testing pressure is based on the MOP (maximum operation pressure) and would result in a testing pressure of only 4.2 bar for a MOP of 10 bar. The PE100+ Association takes that into consideration and raises it''s requirement in terms of the testing pressure in the S4 test up to minimum 10 bars. Straight test pipe

Pressure Testing HDPE Pipe | Field Testing of PE Pipe

It is common practice to pressure-test a pipe system prior to placing it in service. Tests may be conducted using hydrostatic or pneumatic pressure. However, the Plastics Pipe Institute does not recommend pneumatic pressure testing of an above-ground installation, for which the test should be conducted hydrostatically, using a non-hazardous

Guidance for Field Hydrostatic Testing Of High Density

The factors which affect the hydro-testing of HDPE pipe during commissioning procedures are: the creep characteristics of the PE pipe, the percentage volume of trapped air in the pipeline, and temperature The hydrostatic test pressure is usually between 1.25 times the nominal

Engineering Recommended & Technical Testing Data

HDPE Pipe Pressure Testing Outside The Trench: • If specified by the engineer, pressure testing may be conducted prior to pipe installation. • After the pipe has been joined, fill it with water, carefully bleed off any trapped air. Subject the pipe to a hydrostatic test pressure that is 1.5 times the system design pressure for a maximum of

Pressure Tests of Piping systems-Hydrotest Vs Pneumatic

what is the minimum air pressure test for pipes for bs 1387 pipes. Sourav Gho ― June 22, 2017 - 1:40 pm Reply. All water piping shall be tested to hydro-static test pressure of at least one and a half times the maximum operating pressure but not less than 10 kg/sq cm for a period of not less than 24 hours. Why 24 hours is required?

Pneumatic Testing of Pipelines as an Alternative to

Pneumatic Testing of Pipelines as an Alternative to Hydrostatic Testing David Simpson posted on Compressing air from atmospheric pressure up to 900 psig at sea level at constant temperature would result in gas fitting into a volume that is 1/63 the initial volume. If proper procedures are written and followed then a pipe failure in a

1431 Hydrostatic Pressure [spec] - Tucson

waterline, or any valved section thereof, to maintain pressure within 5 psi of the specified test pressure after the pipe has been filled with water and all air expelled. Leakage shall not be measured by a drop in pressure in a test section over a period of time.
