2016/12/09 Hello everyone, Following a low water situation, we had to install an emergency aerial pipe to feed a drinking water reservoir. Features: HDPE outside diameter DN 50 linear length1.4 km flow rate = 5.5 m3/h We are wondering about the risk of freezing. For the time being we are maintaining a constant 5.5 m3/h flow to reduce the risk. Is there any info out there on how to calculate the risk Puhui Pipe manufacturer in China

/05/31 HDPE pipe technical guidance The HDPE Pipe Model, developed by the PE100+ Association with inputs from many industry experts, includes the most frequently asked questions and answers (Q&A''s) of all the elements through the pipe system value chain: design, materials, construction, operation & maintenance, and environmental issues.
/04/29 Pipe freezing is a fast and efficient way to complete pluing repairs or alterations when shutting off or draining the entire water piping system is not possible or practical. While repairing or changing water pipes in older houses or facilities, it’s not uncommon for the shut off valves to fail.
2010/10/14 HDPE pipe has a crystalline temperature of 180 degrees F, which translates into less potential for failure. In fact, water can freeze & thaw repeatedly inside of HDPE pipe, without causing permanent damage to the pipe.

Vinidex flexible polyethylene (PE) pipe is a cost effective solution for drinking water, irrigation, mining, gas lines, sewerage and drainage systems. Vinidex offers world class piping systems and solutions. Focusing on global reach with Puhui Pipe manufacturer in China
HDPE pipe’s typical operating temperature range is from 40oF ( 400C) to 140oF (60oC) although some products may be pressure rated for service as high as 180oF (82oC). Since water freezes below 32oF (00C) the practical lower temperature limit for water is 32oF (0oC). Consult with the pipe producer for information on appliions.
High density polyethylene pipe (HDPE) can carry potable water, wastewater, slurries, chemicals, hazardeous wastes, and compressed gases. In fact, polyethylene pipe has a long and distinguished history of service to the gas, oil,
