825 Nickel Alloy Muti Core Tubing 10000m With Rilsan PA 11 Encapsulation

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 multi core tubing. 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.

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.

Eddy Current Testing

MTSCO configures in-line eddy current testing equipment on the production line to perform 100% testing on multi core tubing 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.

Specifications

Hydraulic / Air tight testing

Hydraulic and air tight test are necessary procedures to verify the pressure sealing performance of multi core tubing. 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.

Siri Laboratory Introduction

Siri Laboratory is equipped with tensile testing machines, impact testing machines, metallographic microscopes, hardness testers, and other equipment, capable of conducting various mechanical property tests including tensile testing, flaring testing, flattening testing, bending testing, and hardness testing. At the same time, the laboratory conducts professional testing such as chemical composition analysis, intergranular corrosion testing, and metallographic analysis. The laboratory's comprehensive testing system provides reliable quality assurance for Siri Tubing products.

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 operating pressure of multi core tubing?

A2: Multi core tubing has 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.

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.
