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 chemical injection lines, capillary tubes, 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.
Manufacturing Process Flow
The production of chemical injection lines begins with steel strip. First, incoming inspection of the raw steel strip is conducted to confirm the material is correct; then strip butt welding is performed. The welded strip is cleaned first, then formed into a tube shape, and the tube body is formed through laser welding. Next, the product undergoes sizing, cold drawing, and in-line bright annealing processes. The formed chemical injection line also requires in-line eddy current testing as well as hydrostatic or airtight testing to verify weld integrity and pressure sealing performance. Finally, the product undergoes precision winding, marking, final inspection, plastic encapsulation, packaging, and warehousing, with shipment arranged according to customer requirements.
Laser Welding Process
Laser welding is a key process that determines the quality of chemical injection lines. 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.

TP316/TP316L/TP316Ti Austenitic Stainless Steel
TP316 adds molybdenum to the 304 composition. This significantly enhances resistance to chloride ion corrosion. It performs excellently in marine environments and media containing halide ions. TP316L is the low-carbon variant. Its carbon content is ≤0.03%. It is suitable for complex components where post-weld heat treatment is not feasible. TP316Ti contains added titanium. Titanium stabilizes carbides, effectively preventing intergranular corrosion. It offers better long-term stability in high-temperature environments.
Eddy Current Testing
MTSCO configures in-line eddy current testing equipment on the production line to perform 100% testing on chemical injection lines 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.
FAQ
Q1: What is the maximum length of chemical injection lines?
A1: Our chemical injection lines can reach a maximum length of 50,000 feet, approximately 15 km, per coil. Ultra-long continuous production reduces the number of field splices.
Q2: What quality certifications does the product have?
A2: 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% hydrostatic testing and eddy current inspection before shipment.
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. All packaging and loading processes are photographed and archived.
