Incoloy 825 Chemical Injection Line Tube

Short Description:

One of the main challenges in the upstream processes of the oil and gas industry is to protect pipeline and process equipment against waxes, scaling and asphalthane deposits. The engineering disciplines involved in flow assurance play an essential part in mapping the requirements that reduce or prevent loss of production due to pipeline or process equipment blockage. Coiled tubing from Meilong Tube is applied to umbilicals and chemical injection systems play an effective role in chemical storage and delivery at an optimizing flow assurance.
