The main points of process operation in the production of polyethylene gas pipes

September 27, 2022

The gas pipes commonly used in modern society are generally polyethylene gas pipes, which are generally high-density polyethylene gas pipes, and are mainly used for plastic pipes for transporting coal gas, liquefied gas and natural gas. This kind of plastic pipe has excellent low temperature resistance, chemical corrosion resistance and good electrical insulation performance.

1. Polyethylene gas pipes produced by plastic extruders need to be used in special environments, so we sometimes add some antistatic agents and ultraviolet absorbers, which can effectively improve the service life of pipes in special environments.
2. In order to improve the performance of the polyethylene gas pipe extruded by the extruder production line and reduce the production cost of the PE pipe, it is generally necessary to add no more than 6% of light calcium carbonate or no more than 15% of carbon black into the resin. , which can be beneficial to improve the antistatic and weather resistance of the pipe.
3. The molding die structure installed on the extruder can directly select the molding die of the HDPE water pipe.
4. In order to improve the strength of HDPE gas pipe in the production process, we need to adopt rapid cooling and cooling method after extrusion molding, which can make the crystallinity small and the surface gloss of the product.

The above is the The main points of process operation in the production of polyethylene gas pipes we have listed for you. You can submit the following form to obtain more industry information we provide for you.
