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.
PVDF Encapsulation
PVDF (polyvinylidene fluoride) is a high-performance engineering plastic. It features outstanding chemical resistance, weather resistance, and UV resistance, and does not age easily even after long-term outdoor exposure. PVDF offers high mechanical strength and good toughness, combined with excellent wear resistance and flame retardancy. It is widely used in chemical piping, semiconductor equipment, and the photovoltaic industry. MTSCO provides PVDF coating solutions, meeting the stringent requirements for corrosion resistance and durability across various industries.
Eddy Current Testing
MTSCO configures in-line eddy current testing equipment on the production line to perform 100% testing on control line flatpack after laser welding. Eddy current testing utilizes the principle of electromagnetic induction—when the probe scans the surface of the tube, abnormal electromagnetic signals occur in the weld area, and the system automatically identifies and marks defect locations. Eddy current testing has high efficiency and extremely high sensitivity. This method can detect defects such as surface cracks, pores, and lack of penetration.
Hydraulic / Air tight testing
Hydraulic and air tight test are necessary procedures to verify the pressure sealing performance of control line flatpack. 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.
FAQ
Q1: What quality certifications does the product have?
A1: Siri Tubing has obtained ISO 9001 quality management system certification. All raw materials come from renowned steel mills; the production process is fully traceable; finished products undergo 100% eddy current inspection before shipment.
Q2: Can non-standard size customization be produced?
A2: Yes. We support customization of outer diameter, wall thickness, length, and encapsulation material according to customer requirements. The outer diameter range covers 3.18 mm to 38.1 mm, with wall thickness from 0.4 mm to 2.54 mm.
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.
