PE (polyethylene) hoses are generally not suitable for transporting oily substances, as polyethylene generally does not have sufficient oil resistance. PE hose is mainly used to transport water or other non-oil liquids, such as drinking water, irrigation water or some chemicals. If you need to transport oily substances, you should choose pipes and tubing specifically designed for this purpose, usually a material with good oil resistance, such as polyvinyl chloride (PVC), polypropylene (PP), polyurethane (PU) or metal pipes.
Transporting oily substances requires special piping materials and designs to ensure safety and performance. When choosing an appropriate piping system, you should follow relevant regulations and standards, and consult professional engineers or experts in related fields to ensure that the piping system meets the requirements. Improper selection of piping materials can lead to leaks, contamination and safety issues.
