Why choose MTSCO Welded Coiled Tubing?

MTSCO is a leading industrial piping system supplier focusing on providing high performance metal piping solutions for global engineers and EPC projects. Our welded coiled tubing production base, Siri Tubing, has a 7,000 m² professional factory with a monthly capacity of 150 tons. The factory is equipped with advanced laser welding and continuous cold drawing production lines, capable of producing ultra long continuous tubes with a single reel length of up to 15,000 meters. MTSCO always adheres to the factory direct supply model combined with a strict quality management system to ensure the delivery of reliable and high quality products for your energy projects.

Three points to ensure product quality

·Secondary inspection mechanism for raw materials: MTSCO raw materials are purchased from large steel mills. Each batch of materials must not only be accompanied by a material test certificate (MTC) and PMI report, but we also conduct secondary PMI re-testing after they enter the Siri Tubing to ensure the chemical composition fully meets standards from the source. MTSCO insists on this strict material selection standard to ensure products have excellent corrosion resistance in harsh environments.

·Full process production traceability: Our core processes include 100% laser welding, cold drawing, bright annealing, and surface protection. Each process is documented with photos by professional QC. Through full process "process card" management, MTSCO ensures precise traceability from strip entry to finished product delivery, achieving a closed loop of quality management.

·100% comprehensive inspection before shipment: The quality inspection team of Siri Tubing conducts routine inspections on appearance, size, quantity, and PMI for finished tubes. All MTSCO welded coiled tubing must pass 100% high pressure hydrostatic testing, with conventional pressure at 5,000 psi and a maximum of 15,000 psi. Additionally, we support third party inspections such as SGS, TUV, and BV to ensure delivery quality is foolproof.

Specification

Are Spiral Wound Tubes safe enough during transportation?

To ensure that ultra long stainless steel spiral wound tubes maintain excellent surface quality during international transportation, we provide comprehensive customized packaging solutions. For different outer diameters, wall thicknesses, and reel weights, MTSCO is equipped with various spool options including plastic reels, plywood reels, solid wood reels, iron frame wood reels, and full iron reels. For large span and heavy duty coiled tubing, we recommend using high strength iron frame wood reels or full iron reels to ensure structural stability during winding and pay off. Each reel delivered by MTSCO undergoes precision spooling to prevent extrusion or tangling during sea transportation.

What working conditions is the product suitable for?

In oil drilling and offshore engineering, stainless steel spiral wound tubes are commonly used for chemical injection lines, hydraulic control lines, and downhole operation systems. These tubes must maintain sealing integrity under extreme pressure and highly corrosive environments. MTSCO coiled tubing products are widely used in geothermal wells, offshore oil and gas platforms, and deep sea sampling systems. Our tubes can withstand hydraulic tests of up to 15,000 psi, perfectly adapting to complex downhole conditions and significantly reducing construction costs and leakage risks for customers.

FAQ

Q1: What is the maximum pressure your welded coiled tubing can reach?

A1: Our tubing can reach a maximum hydraulic test pressure of 15,000 psi. MTSCO uses advanced laser welding and continuous cold drawing technology to make the weld strength highly consistent with the base metal, ensuring stable operation in high pressure downhole environments.

Q2: What is the maximum length per reel for this multi core control line?

A2: Our welded coiled tubing can reach a maximum length of 50,000 feet (about 15 km) per reel, meeting the needs of long distance downhole wiring, reducing field joints, and improving system reliability. The MTSCO factory possesses ultra long continuous production capabilities.

Q3: What are the main materials for MTSCO coiled tubing?

A3: We provide a comprehensive range of stainless steel, duplex steel, and nickel alloy coiled tubing, including 304, 316L, 2205, 2507, alloy 625, and 825. All raw materials are purchased from internationally renowned steel mills, and each batch undergoes PMI material re-testing to ensure compliance with international standards such as ASTM.
