Meilong is a supplier of welded and redrawn, seamless and redrawn
coiled tubing which are made from corrosion-resistant austenitic,
duplex, super duplex stainless steels and nickel alloy grades. We
have been specializing in manufacturing coiled tubing used in the
oil and gas industry.
Tubing for Control Lines
A direct 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.
Tubing for Chemical Injection
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.
Our tubing is characterized with integrity and quality to be
specially used in subsea conditions in the industries of oil and
gas extraction.
Super Duplex 2507 material provides excellent corrosion resistance
in chloride-containing environments.
All Super Duplex 2507 control line tubing offered by MEILONG are
made from a controlled-chemistry. Alloy 2507 material with minimum
pitting resistance equivalent (PRE) value of 42.5
Size include 1/4’’, 3/8’’, 1/2’’, 5/8’’, 3/4’’, and 1 in. outside
diameter.
Tubing nominal wall thickness meets ASTM A-789
Tube markings include size, material type/grade, specification,
heat number, and other information.
