Company & Factory Introduction

MTSCO is a professional factory complex in the industrial piping sector, operating four major product divisions. In 2024, MTSCO established its own production base—Siri Tubing—specializing in the manufacturing of welded coiled tubing, control line flatpack, encapsulated control line, multi-core tubing, and cables. The factory strictly follows international ASTM standards and can supply various materials including 304, 316, 2205, 2507, Alloy 625, and Alloy 825. Siri Tubing has obtained ISO certification and has long-term partnerships with international energy companies such as OXY, KOC, and ADNOC. We are not just selling products, we are also your reliable supply chain partner.

Product Advantages

·Ultra-long continuo us production: Multi core tubing can reach a maximum length of 50,000 feet (approximately 15 km) per coil, reducing field splices and improving system reliability.

·High-pressure bearing capacity: Multi core tubing has a standard hydraulic test pressure of 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.

·Diversified encapsulation materials: Provides multiple plastic encapsulation options including FEP, PVDF, Rilsan PA 11, and Santoprene TPV, meeting different working condition requirements.

·ISO certification guarantee: Siri Tubing has obtained ISO 9001 quality management system certification, ensuring stable and controllable product quality.

·Fast delivery capability: Regular specifications are kept in stock year-round, enabling rapid response to urgent customer needs and ensuring on-time delivery.

Laser Welding Process

Laser welding is a key process that determines the quality of multi core tubing. MTSCO adopts 100% laser welding process, using high-energy-density laser beams to precisely melt the formed tube. The welded seam has narrow width and small heat-affected zone, effectively avoiding oxidation and embrittlement. Laser welding ensures beautiful weld formation and strong dimensional consistency. During production, laser welding parameters are adjusted in real-time by an automatic control system to ensure stable and reliable quality of every weld seam.

Santoprene TPV Encapsulation

Santoprene TPV (thermoplastic elastomer) combines the soft feel of rubber with the processability of plastic, offering excellent weather resistance, ozone resistance, and chemical resistance. With outstanding sealing performance and a comfortable tactile feel, it is commonly used in automotive seals, medical devices, and consumer goods. TPV is recyclable, aligning with environmental sustainability trends. MTSCO offers Santoprene TPV encapsulated solutions to meet customers’ comprehensive needs for elasticity, durability, and aesthetic appeal.

Hydraulic / Air tight testing

Hydraulic and air tight test are necessary procedures to verify the pressure sealing performance of multi core tubing. MTSCO conducts pressure testing on all welded coiled tubing, with a standard test pressure of 5,000 PSI and a maximum withstand test pressure of 15,000 PSI. Hydraulic test detects deformation and leakage of the tube body and weld seam under high pressure by injecting pressurized water into the tube; air tight test is used for scenarios with higher sealing requirements and can quickly detect micro-leakage. Both testing methods can be flexibly selected according to customer requirements to ensure products meet the pressure requirements of different working conditions. After testing is complete, all data records and samples are retained and archived.
