Company and Factory Introduction

MTSCO provides stainless steel and nickel alloy product solutions for global industrial piping projects, serving industries such as oil and gas, chemicals, marine, and heat exchange equipment. For control line products, MTSCO established its own factory, Siri Tubing, in 2024, specializing in the production of welded coiled tubing, geothermal coiled tubing, control line tubing, and multi-core cables, all of which are ISO-certified. Leveraging our in-house manufacturing capabilities, MTSCO ensures more consistent quality control, reliable delivery coordination, and robust project support. We do more than just sell products—we are your trusted supply chain partner.

Application Scenarios

Geothermal coiled tubing are primarily used in geothermal well development, geothermal energy extraction, downhole fluid transport, chemical injection, pressure monitoring, and temperature monitoring. Since geothermal environments typically involve high temperatures, high pressures, corrosive media, and continuous deep-well operations, there are stringent requirements for the pipes’ corrosion resistance, pressure-bearing capacity, weld stability, and continuous length. MTSCO geothermal coiled tubing is available in various materials and lengths to meet project requirements, making it suitable for geothermal power generation, district heating, downhole control systems, and complex energy development projects.

Geothermal Coiled Tubing Final Product Inspection Process

In high-pressure transport applications such as oil and gas, downhole operations, and deep-sea environments, the operational stability of coiled tubing is central to risk management. To this end, MTSCO has established a rigorous final product inspection system to ensure that coiled tubing meets quality standards.

First, the quality team verifies material composition through PMI testing to eliminate the risk of material mix-ups. Second, inspectors conduct rigorous dimensional and visual inspections to ensure the product’s physical specifications fully comply with engineering requirements. Given the continuous-length production process, technicians use Eddy Current Testing (ET) to identify deep-seated defects in the tubing. Subsequently, quality inspectors perform hydraulic/air tight tests to verify the product’s pressure integrity under simulated operating conditions. Finally, we test the product in the laboratory to ensure all performance specifications are met.

Hydraulic and Air Tight Test

To verify product reliability under extreme pressure, the production laboratory performs rigorous hydraulic test/air tight test on every coil of finished coiled tubing. Test engineers first seal both ends of the tubing and use a high-pressure pump system to inject water or high-purity nitrogen into the tubing, gradually increasing the internal pressure to multiples of the design standard. During the specified pressure stabilization period, high-precision sensors monitor the pressure curve in real time to confirm that the tubing exhibits no deformation or leakage when simulating deep-sea high-pressure or downhole conditions.

FAQ

Q1: What is the maximum operating pressure of the coiled tubing?

A1:Our welded coiled tubing undergoes standard hydraulic testing at 5,000 PSI and can withstand a maximum test pressure of 15,000 PSI, meeting the requirements of the vast majority of high-pressure applications.

Q2: What packaging options are available for the coils? How do you prevent damage duing transport?

A2: We offer a variety of packaging options, including plastic reels, wooden reels, solid wooden reels, iron reels, iron and wooden reels, and wooden boxes. We reinforce the coils with wooden strips and ropes when loading them into crates to prevent impact during transport and ensure the goods arrive safely.

Q3: Can you produce encapsulated tubing?

A3: Yes, we specialize in producing coiled tubing with plastic coatings in various materials, including PVDF, FEP, and PA. The coating provides additional corrosion resistance and mechanical protection, making it suitable for applications such as downhole control lines and instrumentation conduits. MTSCO’s co-extrusion coating technology ensures uniform coating and strong adhesion, fully complying with oil and gas industry standards.
