Company Profile
MTSCO is a manufacturing and supply platform for industrial piping systems. Our business encompasses a wide range of stainless steel and nickel alloy piping products. In 2024, MTSCO established its own manufacturing facility, Siri Tubing, which specializes in the production of welded coiled tubing, capillary tubes, control line tubing, multi-core tubing, and cables. We offer welded coiled tubing in lengths of up to 50,000 ft per coil. MTSCO integrates manufacturing, inspection, packaging, and delivery into a single process, enabling customers to streamline procurement and project execution more efficiently. If you are evaluating solutions for control line or welded coiled tubing, please contact MTSCO to discuss your specific requirements.
Single Process Introduction—Laser Welding
Laser welding is one of the key processes in welded coiled tubing production, directly affecting weld quality, dimensional stability, and the results of subsequent processing. It is a welding method that focuses a high-energy laser beam on the metal joint area, causing the material to melt rapidly within a small area and form a weld. Compared to traditional welding, laser welding offers more concentrated heat input and faster welding speeds. MTSCO’s welded coiled tubing production process incorporates 100% laser welding, better meeting requirements for continuous length and consistent quality.

Inspection Methods
The focus of pipeline inspection extends beyond dimensions to include weld integrity, pressure-bearing capacity, and material consistency. Routine inspections cover visual inspection, PMI, dimensional verification, air tightness testing, ET, and hydrostatic testing, with standard pressure at 5,000 PSI and a maximum of 15,000 PSI. MTSCO’s welded coiled tubing undergoes a comprehensive inspection process prior to shipment to ensure product quality before leaving the factory.
Application Scenarios Of S31803 heat coil tubes
S31803 heat coil tubes are primarily used in oil and gas, geothermal, heat exchanger, and shipbuilding applications, and are also suitable for complex installation environments such as deep-sea and underground settings where maintenance costs are high. These products typically require continuous lengths, stable pressure resistance, and consistent weld quality to reduce on-site joint risks and construction costs. MTSCO’s control line has long served these industrial applications, and we can also provide customization based on length, material, and plastic sealing requirements.
FAQ
Q1: What materials are commonly used for these products?
A1: Common materials include 304, 316, 2205, 2507, Alloy 625, and 825. MTSCO can select materials based on the medium, pressure, and corrosive environment.
