Polyurethane lined pipe elbow is a pipe fitting made of polyurethane material used to change the direction of a pipe or connect two pipes at different angles. Polyurethane lined pipe elbows are usually composed of polyurethane pipes and steel elbows. The inside of the steel elbow is covered with polyurethane lining to provide better wear resistance, corrosion resistance and high temperature resistance.

Some application scenarios of polyurethane lined pipe elbows:

Oil and natural gas industry: In the process of oil and natural gas extraction and transportation, pipelines often need to pass through harsh environments, such as deserts, swamps, mountains, etc. In these areas, pipes are susceptible to wear and corrosion. Polyurethane lined pipe elbows can effectively protect pipes and extend their service life.

Chemical industry: In the chemical production process, pipelines often need to transport various chemical substances, such as acids, alkalis, salts, etc. These chemicals have a strong corrosive effect on pipes. Polyurethane lined pipe elbows can effectively prevent chemical corrosion on the elbow and ensure the safe operation of the pipeline.

Electric power industry: In the electric power industry, flue gas desulfurization, dust removal and other processes require the use of a large number of pipelines. These pipes often need to withstand high temperature, high pressure, and high humidity environments. Polyurethane lined pipe elbows have good high temperature resistance, which can ensure that the pipes can still maintain good mechanical properties and chemical stability in high temperature environments.

Shipping industry: Pipelines in the shipping industry often need to withstand corrosion and impact from seawater. Polyurethane lined pipe elbows have good corrosion resistance and impact resistance, which can ensure safe and reliable operation of pipelines in the shipping industry.

Construction industry: such as river sand pumping, sand washing and other industries.
