POLYETHYLENE UHMW HDPE LDPE

HDPE has very good chemical resistance of corrosives as well as stress cracking resistance (with the exception of strong oxidizing acids at elevated temperatures). Certain hydrocarbons cause only a light surface swelling at moderate temperature. Water Resistant Moisture and water (including saltwater) have no affect on HDPE.

ASTM A36 Carbon Steel vs. HDPE :: MakeItFrom

ASTM A36 Carbon Steel vs. HDPE. ASTM A36 carbon steel and HDPE belong to fundamentally different material chemistries. ASTM A36 carbon steel is a metal, while HDPE is a polymeric material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 7 material properties with

Design of PE Piping Systems - Plastics Pipe Institute

Design of PE Piping Systems 159 The Hydrostatic Design Stress, HDS, is the safe long-term circumferential stress that PE pipe can withstand. It is derived by applying an appropriate design factor, DF, to the Hydrostatic Design Basis, HDB. The method for establishing the Hydrostatic Design Stress for PE pipe is described in Chapters 3 and 5.

Polyethylene & Polypropylene in Flexible Barrier Packaging

Crystallinity yFor polyethylene, the degree of crystallinity has the largest influence on barrier properties. yRandomly oriented, large crystals, create the most tortuous path. y% crystallinity can be measured and is influenced primarily by polymer type, but also by processing. yLDPE/LLDPE ~ 30% - 55% crystallinity yHDPE up to 85% crystallinity yIn addition to % crystallinity, morphology

Replacing water supply line: PEX vs. black polyethylene

We have gotten two quotes to replace our old galvanized water supply line (pipe from the water main to our house). One pluer uses PEX and the other uses black polyethylene. I know both options are cheaper than copper and both seem to be good options, but I don''t know if PEX is better than black poly/PE. The PEX quote is a bit higher, and I wondered if it was because of the

Chemical Resistance of Polypropylene and Polyethylene

Generally speaking, the chemical resistance of polypropylene and polyethylene is considered superior to that of met-als. They are unaffected by most inorganic acids, alkalis, and aqueous solutions which rapidly corrode metals, although some concentrated acids and oxidizing agents can attack them, especially at elevated temperatures.

Ecolife Recycling - How to Recycle HDPE (Plastic #2)

It saves landfill space, energy, water, resources, and reduces pollution. Consider, for instance, recycling HDPE plastic bags - making new bags from post-consumer content uses 67% less energy, 90% less water, and produces 33% fewer sulfur dioxide emissions, 50% fewer nitrous oxide emissions, and 87% fewer carbon dioxide emissions.

HDPE Pipe

Warning: All pipe plugs must be blocked or anchored adequately against a force equal to the head pressure times the cross-sectional area of the pipe. Debris or protrusions in the pipeline can damage a seal or rupture inflatable plugs. NEVER use an inflatable plug when its failure could cause injury or astrophic damage or as the only means of protection for personnel working downstream.

Pipe Flow Calculator. Liquid or Gas Pipe Design - Pressure

For our pipe flow calculator, all of the pipes have the same diameter, so you can add up all your minor loss coefficients and enter the sum in the Minor Loss Coefficient input box. Why do I sometimes get the message when running the pipe flow calculator, "Infeasible Input"? The governing equations for fluid flow must be satisfied.
