Get A QuoteASTM A213 TP304L Seamless Tube
304L stainless steel has excellent resistance to pitting corrosion and stress corrosion cracking due to its low carbon content, and is particularly suitable for the chemical, petroleum, food and pharmaceutical industries. Its high content of chromium and nickel enables it to maintain good strength and good oxidation resistance under high temperature conditions.
ASTM A213 TP304L pipe has excellent high temperature resistance and corrosion resistance, and is particularly suitable for fluid transportation in high-temperature steam, hot water and acidic environments. It is widely used in many industries such as petroleum, chemical, energy, food processing and pharmaceutical equipment, especially in heat exchangers, boilers and evaporators, etc., providing it with long-lasting stability and efficient heat conduction performance.

Factory Introduction:
MTSCO seamless tubes have a highly guaranteed supply chain. MTSCO has invested in a factory - HUXIN PIPE, which has 35 years pipe manufacturing experience. MTSCO has reached a high strategic partnership with Huxin, becoming the only international sales center of Huxin. Fully responsible for the global sales and promotion of HUXIN.
HUXIN has obtained the ISO/PED/AD2000/M650 certificate and is equipped with a complete set of advanced production equipment, inspection equipment, and laboratory instruments, such as cold rolling machine, 24m annealing furnaces, pickled pool, ultrasonic eddy current integrated machines, etc. From production to quality assurance, protect your seamless tubes. The exclusive cooperation mechanism allows us to collaborate perfectly, increase order volume and production capacity, and provide you products with higher cost-effectiveness.
Quality Control Method:
First, secondary inspection of raw materials
Our raw materials come from large factories such as Baosteel and TSINGSHAN. Each batch of raw materials requires MTC and PMI. After the raw materials arrive, we conduct PMI and other inspections again to ensure that they meet the requirements
Second, traceability of the production process
Each process is equipped with advanced production equipment, and is supervised by experienced engineers and technicians. Each link is supervised by professional qc inspectors and photographed for archiving. The entire process uses process cards to ensure accuracy and traceability.
Third, 100% inspection before shipment
MTSCO has professional QC team to conduct a series of inspections and experiments on the tubes, including routine appearance, PMI, size, quantity, and other inspections. At the same time, we also conducts mechanical testing, hardness testing, UT, ET, HT and other tests. In addition, we also accept third-party inspection, such as SGS, TUV, and BV.
Before shipping, we use appropriate and safe packaging methods and take measures such as container reinforcement to ensure that your goods are delivered to you in good condition.
