Meilong is a supplier of welded and cold drawn, welded and seamless umbilical tubing which are made from corrosion-resistant austenitic stainless steel 316L. We have been specializing in manufacturing coiled umbilical tubing used in the oil and gas industry.

316L coiled tubing for Chemical Injection in umbilicals
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. Steel tubing from Meilong is applied to umbilicals and chemical injection systems play an effective role in chemical storage and delivery at an optimizing flow assurance.

316L Stainless Steel Tubing in umbilical that

Provides hydraulic power to subsea control system

Delivers chemicals for subsea injection at the subsea Christmas tree or downhole

Can provide bulk methanol

Can provide gas for gas lift


316L coiled tubing for hydraulic control line in umbilicals

A direct 316L hydraulic control umbilical provides direct hydraulic control of each valve on a subsea christmas tree, through a bundle of tubes from the topsides hydraulic power unit (HPU) to the subsea tree. No electrical power or signal is required. Actuation of valves is by the supply of hydraulic power to the relevant tube. This is accomplished by opening the relevant valve on the manifold located on the topsided HPU. This type of umbilical is limited to subsea production systems with short offsets to the host and few trees.

Thanks to the experience and expertise gained in the production and inspection, the tubes supplied by Meilong fully meet stringent quality requirements of the oil & gas industries. The tubing deployed in the umbilicals used in aggressive subsea and downhole conditions.
