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.
Laser Welding Process
Laser welding is a key process that determines the quality of control line flatpack. 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.
Application Areas
MTSCO control line flatpack products are widely used in oil and gas, geothermal, heat exchangers, and shipbuilding industries. In the oil and gas sector, control lines are used for downhole allocation, pressure monitoring, and fluid control; in geothermal power plants, the products' high temperature and corrosion resistance meet the requirements of harsh working conditions; in heat exchanger and shipbuilding manufacturing, precision coiled tubing can be used for medium transmission and instrument connections. Siri Tubing's high-performance control line flatpack has been successfully applied in harsh environments such as deep sea and underground. We support customization according to customer needs, helping clients select the most suitable products.
S32750 (2507) Super Duplex Stainless Steel
S32750, also known as 2507, is a super duplex stainless steel. This material combines the microstructural characteristics of both austenitic and ferritic steels. It offers high strength and excellent corrosion resistance. Its yield strength can reach over 500 MPa, which is significantly higher than that of ordinary stainless steel. The pitting resistance equivalent number (PREN) of 2507 is ≥40. Its resistance to chloride-induced stress corrosion is particularly outstanding. 2507 performs exceptionally well in chloride-containing environments and offers good weldability and formability.
Quality Control System
·Raw Material Re-inspection: All raw materials come from qualified suppliers such as POSCO, ATI, JISCO and other internationally renowned steel mills. Upon arrival, the QC team performs PMI composition re-inspection to ensure the material meets order requirements.
·Traceable production process: The main production processes include 100% laser welding, cold drawing, and bright annealing. Each production stage is supervised on-site by experienced technicians. The entire production process uses process cards, supporting full-process traceability.
·Pre-shipment full inspection: Siri Tubing has a professional QC team that conducts a series of inspections and tests on finished products, including routine appearance inspection, PMI test, dimension inspection, and more. At the same time, special inspections such as air tight test, hydraulic test, and eddy current testing are conducted.
FAQ
Q1: What encapsulation materials are available for encapsulated control lines?
A1: We offer four plastic encapsulation materials: FEP, PVDF, Rilsan PA 11, and Santoprene TPV. FEP and PVDF have excellent chemical corrosion resistance, while Rilsan PA 11 offers good flexibility. You can select the most suitable encapsulation material based on the specific application environment.
Q2: What is the maximum length of control line flatpack?
A2: Our control line flatpack can reach a maximum length of 50,000 feet (approximately 15 km) per coil. Ultra-long continuous production reduces the number of field splices.
Q3: What packaging methods do you support?
A3: We offer multiple packaging options including plastic reels, wooden reels, solid wooden reels, iron reels, iron-wood combined reels, and wooden boxes. Wooden strips and ropes are used for reinforcement during container loading to ensure products arrive intact in long-distance transportation.
