Physical properties[edit]

Polyethylene is a thermoplasticpolymer consisting of long hydrocarbon chains. Depending on the crystallinity and molecular weight, a melting point and glass transition may or may not be observable. The temperature at which these occur varies strongly with the type of polyethylene. For common commercial grades of medium- and high-density polyethylene the melting point is typically in the range 120 to 180 °C (248 to 356 °F). The melting point for average, commercial, low-density polyethylene is typically 105 to 115 °C (221 to 239 °F).it is transprant.

Chemical properties[edit]

Most LDPE, MDPE and HDPE grades have excellent chemical resistance, meaning that it is not attacked by strong acids or strong bases. It is also resistant to gentle oxidants and reducing agents. Polyethylene burns slowly with a blue flame having a yellow tip and gives off an odour of paraffin. The material continues burning on removal of the flame source and produces a drip.^[3] Crystalline samples do not dissolve at room temperature. Polyethylene (other than cross-linked polyethylene) usually can be dissolved at elevated temperatures in aromatic hydrocarbons such as toluene or xylene, or in chlorinated solvents such as trichloroethane or trichlorobenzene.^[4]

Q:Plastic pipe leakage can use plugging Ling?: Dry leakage parts, with Wang Yu (waterproof cement) to buy. Less water, very thick situation, large surface paste in the water leakage position. We often use this method to remedy cast iron pipes

Q:UPVC pipe, HDPE pipe construction, useful 360 degrees full package foundation, what does that mean, gravel cap or concrete?.: 360 degrees full package meaning is, tube all buried in the foundation, of course, the foundation is most likely sand or gravel foundation. That is to say, the base layer should be backfilled at least to the same height above the pipe roof

Q:About plastic drain pipe expansion joint: The expansion joint of the transverse tube shall not use the expansion joint of the vertical pipe, and the pressure bearing performance of the special expansion joint of the transverse tube shall not be less than 0.08MPa.

Q:What is the maximum temperature plastic tubes can withstand without deformation?: The maximum temperature that plastic tubes can withstand without deformation varies depending on the specific type of plastic used. However, most common plastics can typically withstand temperatures ranging from 100 to 150 degrees Celsius without significant deformation. It is important to consult the manufacturer's specifications or conduct specific testing to determine the maximum temperature tolerance of a particular plastic tube.

Q:Can plastic tubes be used for shipping fragile items?: Yes, plastic tubes can be used for shipping fragile items. They provide a protective and secure packaging option, especially for small and delicate items such as posters, artwork, or thin glass items. The durable and rigid nature of plastic tubes helps prevent breakage and damage during transit. Additionally, plastic tubes can be customized with padding or cushioning materials to provide extra protection if needed.

Q:What are the common sizes of plastic tubes used for HVAC?: The common sizes of plastic tubes used for HVAC vary but typically range from 1/4 inch to 1 inch in diameter.

Q:i have a top fin 30 filter,and i was wondering should bubbles be coming out of the clear plastic tube?: Top Fin Filter Extension Tube

Q:Do plastic tubes have any limitations in terms of gas permeability?: Yes, plastic tubes do have limitations in terms of gas permeability. While some plastics have low gas permeability, others may allow certain gases to pass through. The permeability depends on the type and quality of plastic used. Therefore, it is important to consider the specific application and requirements when selecting plastic tubes for gas containment.

Q:What are the disadvantages of welded steel pipe and plastic pipe?. More points, bonus points: The technology of this product determines its advantages and disadvantages. Generally, the welded steel pipe has high accuracy, uniform wall thickness, high brightness inside and outside the pipe (the surface brightness of the steel pipe surface determined by the steel plate), and can be arbitrarily fixed. Therefore, it reflects its economy and beauty in the application of high precision, medium and low pressure fluid.

Q:What's the outer diameter of the 1 inch 2 tube?: The diameter of the pipe refers to the inside diameter of the tube. Because the wall thickness is different, so the outer diameter is also different1.2 inch internal diameter of about 32mm, outer diameter of about 42.25mmPipe dimensions (British and metric tables)
