Why Choose MTSCO as Your Heat Exchanger Tube Partner?

Established in 2006, MTSCO has built a robust supply chain in the industrial stainless steel sector through our unique "Factory Complexes" model. We maintain deep collaboration with our core manufacturer, HUXIN PIPE. Leveraging its advanced precision tube production capabilities, MTSCO provides global customers with high-standard heat exchanger tubing solutions. HUXIN PIPE is ISO and PED certified, ensuring every tube complies with stringent project specifications.

How We Craft a Seamless Tube

Bright Annealing is a critical step in enhancing the quality of heat exchanger tubes. The tubes undergo heat treatment in an oxygen-free environment with protective gas, effectively eliminating internal stresses without producing oxide scale. This process maintains a mirror-like finish on both internal and external surfaces, significantly reducing fluid resistance and the risk of fouling during operation. MTSCO is equipped with advanced automated bright annealing furnaces capable of processing seamless tubes up to 30 meters in length.

Key Specs at a Glance

How Does Chemical Composition Determine Performance?

TP304 and TP316 are the core materials for stainless steel heat exchange systems. TP304 offers excellent formability, while TP316, through the addition of molybdenum, significantly enhances pitting resistance in acidic and chloride environments. These properties ensure the structural integrity of heat exchange equipment under high temperature and high pressure. MTSCO performs rigorous PMI testing on every batch of raw materials to ensure 100% compliance with chemical composition requirements.

304/316 Heat Exchanger Tube FAQ 

Q1: How do you ensure your heat exchanger tubes are leak-free? 

A1: All 304 and 316 tubes must pass 100% Eddy Current Testing (ET) and hydrostatic testing before leaving the factory. Through rigorous Non-Destructive Testing (NDT), MTSCO identifies even minute defects to ensure zero leakage under long-term pressure environments.

Q2: Is TP316 more durable than TP304? 

A2: Yes. Due to its 2%-3% molybdenum content, TP316 outperforms TP304 in chemical corrosion and saltwater resistance. MTSCO recommends TP316 for offshore engineering or chemical fluid applications to extend equipment maintenance cycles.

Q3: What is the maximum length of your heat exchanger tubes?

A3: We possess the capability to produce single seamless tubes up to 30 meters long. Utilizing these extra-long tubes significantly reduces the number of tube-to-tube sheet weld joints in shell-and-tube heat exchangers, enhancing structural integrity and minimizing potential leak paths.

Q4: Can you provide matching pipe fittings and flanges? 

A4: Absolutely. MTSCO provides one-stop piping system solutions. We own or hold controlling stakes in several component factories, allowing us to supply fittings and flanges that perfectly match the material grade of our 304/316 tubes, ensuring material consistency throughout the entire engineering system.
