Product Description

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.

Application

Duplex 2205 seam welded pressure tubing in the heat treated condition is typically used in oil and natural gas wells for chemical injection applications. In such applications, it is commonly referred to as capillary tubing and is free-hanging (self-supporting) inside the production casing. The chemicals being injected are often used to enhance production flow rates, inhibit corrosion or scaling and/or de-water. However, the tubing can also be used for control line tubing applications including hydraulically actuated surface-controlled subsurface safety valves. For control line applications, the tubing is generally deployed by strapping it to the outside of the production casing. The tubing is frequently supplied as 5,000 to 35,000 ft. coils on a wooden or steel reel, depending on size.

 

Description

Duplex 2205 is a duplex stainless steel. When properly heat treated, the microstructure consists of a nearly equal mixture of the austenitic and ferrite phases. This two-phase microstructure produces a fine grain size which increases the yield strength. In the final heat treated condition, alloy 2205 can achieve a yield strength approximately twice that of austenitic alloys such as 316L, 825 and 625 which must be cold worked to achieve comparable yield strengths. Duplex stainless steels are often classified as lean, conventional, super or hyper based upon their pitting resistance equivalent (PRE or PREN). Various PRE formulas are used to rank an alloy’s resistance to chloride pitting corrosion based upon its composition. Alloy 2205 typically has a PRE of 36 and is considered a conventional duplex stainless steel. Alloy 2205 is often selected for use in oil and gas production environments based upon its higher strength and resistance to pitting, crevice and stress corrosion cracking in chloride containing environments. Consult ISO 15156-3, Table A.24 for the limits regarding the use of alloy 2205 in hydrogen sulfide containing environments for oil and gas production.

 

Manufacturing Process and Resultant Properties

Strip splice welds join lengths of cold rolled strip to enable long lengths between orbital welds (greater than 14,500 ft between orbital welds is achievable). The strip is formed into a tubular cross section and longitudinally seam welded using the gas tungsten arc (GTAW) process. The tubing may be welded at a larger outside diameter, plug-redrawn to final size and subsequently heat treated. The final material condition of the tubing is heat treated.

 

Nondestructive Testing (NDT)

Eddy current testing (ECT) is performed on the longitudinally seam welded tubing and strip splice welds in the as-heat treated condition. Those strip splice welds detected by ECT. Yield pressure hydrostatic testing is performed on the heat treated tubing at final size.
