Meilong Tube has been leading the way with groundbreaking advances in the industry, such as dramatically increasing the length of tubing manufactured without orbital welds. We were also the first to introduce Tube Encapsulated Conductors (TEC) to the oil and gas industry.
We boast a knowledgeable, experienced management team which is passionate about quality management and customer service. With decades of expertise in tubular manufacturing and customer service, our team has the expertise to provide customized, top-notch solutions for our customers’ tubing related needs.
Our goal is to consistently meet and, hopefully, surpass our clients’ expectations in regards to the quality of our products, our ease of business, and the responsiveness of our entire team. The satisfaction of our customers is of utmost priority to us.
At Meilong Tube, we provide quality assurance for our products in several ways, including: chemical, corrosion, dimensional, eddy-current, hydrostatic, elongation, hardness, flare, flatten, grain size, metallurgical, positive material identification (PMI), surface roughness, tensile strength, and yield strength.
We offer a variety of alloy tubing options for use in hydraulic control, chemical injection, and other highly demanding industrial applications. All of our stock alloy tube products meet the UNS and ASTM specifications for quality assurance.
For corrosive environments or conditions, our tubes offer excellent chloride pitting and crevice corrosion resistance, as well as resistance to H2S and CO2, and chloride stress corrosion cracking (SCC). We also carry alloys with a variety of minimum yield strengths for various applications, and all stock tubes are seam-welded for pressure.
Our tube options include the following alloys and their respective UNS and ASTM specifications:
The weight per meter of the capillary line tubing made of Duplex 2507 (UNS S32750) varies according to its Outer Diameter (OD) and Wall Thickness (WT).
The table below shows the weight per meter of capillary line tubing with imperial size and metric size.

Therefore, capillary line tubing made of Duplex 2507 (UNS S32750) comes in various sizes and the weight per meter varies accordingly.
A safety valve is an essential protective device for equipment that functions to automatically open upon reaching a predetermined pressure. This enables it to safely release and relieve the pressure from a pressure vessel, no matter what the cause is; therefore, avoiding explosions at a facility.
Safety valves are set in places within the pressure vessels, and can be compared to devices that will be released in order to mitigate accidents. The safety valve system is usually equipped with a fail-safe system that can easily isolate the wellbore during any system failure or if there is damage to the surface production control facilities.
Subsurface Safety Valves (SSSV)It is a prerequisite to have closure systems for any natural flow wells to ensure safety. This is especially since the installation of a SSSV is able to provide maximum closure capacity during emergencies.
For the SSSV to work, an external stainless steel control line connected to the well tubing has to be installed along the production tubing. Typically, keeping up to 10,000 psi pressure is necessary on the control line to keep the valve open.
Other ApplicationsApart from safety valves, there are other applications of safety systems as well. Examples of such include capillary coiled alloy tubings for chemical injection, steel tube umbilicals, hydraulic control line coiled alloy tubing, work strings, etc.
