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.
Rilsan PA 11 Encapsulation
Rilsan PA 11, bio-based nylon 11, derived from natural castor oil, is an eco-friendly, high-performance polyamide. It offers excellent oil resistance, chemical resistance, and flexibility, along with good wear and fatigue resistance, low moisture absorption, and dimensional stability. PA 11 is widely used in automotive fuel systems, hydraulic lines, sports equipment, and other fields. Metro offers PA 11 overmolding services, customizing formulations and structures based on specific applications to achieve the perfect combination of lightweight design and long service life.

304/304L Austenitic Stainless Steel
304 is the most versatile and widely used austenitic stainless steel. Its alloy composition consists of 18% chromium and 8% nickel. It offers excellent corrosion resistance and good overall mechanical properties. It performs stably in atmospheric environments and general corrosive media. 304 offers good weldability and excellent low-temperature toughness. It is easy to machine and form. 304L is the low-carbon version. It is particularly suitable for thick-plate welding and high-temperature applications.
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 engineers and technicians, with professional QC inspectors participating throughout and taking photos for archiving. 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 composition verification, dimension measurement, and more. At the same time, special inspections such as airtightness testing, hydrostatic testing, and eddy current testing are conducted. Additionally, we support third-party inspections by SGS, TUV, and BV to meet the inspection requirements of international customers.
FAQ
Q1: What is the maximum operating pressure of chemical injection lines?
A1: Chemical injection lines have 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.
Q2: How long is the delivery cycle usually?
A2: Regular specifications and materials are kept in stock year-round, enabling rapid response to urgent needs. Custom specifications are produced according to schedule. We arrange shipment reasonably based on project milestones to ensure on-time delivery without affecting project progress.
Q3: What typical working conditions are the products suitable for?
A3: Chemical injection lines are widely used in oil and gas wellhead control, geothermal power plant heat exchanger systems, ship piping instrument connections, and chemical medium transmission. The products are corrosion-resistant and high-pressure-resistant, particularly suitable for harsh environments such as deep sea and underground.
