Nickel Alloy Welded Pipe, ASTM B705 Alloy 825 Auto Welding Pipe

Parameter Table：

Nickel Alloy 825 pipe:

Nickel Alloy 825 (UNS N08825) is more than one type of basic wall, contains iron, has a higher amount of iron, is a metal alloy with iron and iron, and has excellent anti-corrosion performance. It has a special long resistance to corrosion by sulfuric acid, nitric acid, nitric acid and various other organic acids, and at the same time has a strong resistance to corrosion. Due to its fixed steel content (approximately 38%-46%), the alloy still retains its ability under high temperature and strong corrosion environments, giving it excellent mechanical performance and resistance to corrosion. In addition, the alloy has the added strength of the copper element, which increases its strength and has corrosion resistance due to its physical properties, so that it can be added to the metal to prevent corrosion during contact with the raw crystals. Nickel Alloy 825 Specially designed for special applications such as chemical engineering, petroleum natural gas, acid solution processing, seawater desalination, pollution control, etc.

Factory advantages and features:

Becoming a highly reliable welded pipe manufacturer is the result of MTSCO's strategic investment in HUXIN Pipe Industry, which has 36 years of professional pipe manufacturing experience. The partnership has ensured the delivery of first-class welded pipes with decades of industry experience.

MTSCO's welded pipes are available in a variety of specifications, with diameters up to 3 meters and hydrostatically tested pipes up to 1.5 meters. This diversity of sizes caters to a wide range of industrial applications, providing flexibility to meet specific project requirements.

MTSCO is equipped with state-of-the-art production and inspection equipment such as CNC bending machines, shearing machines, 12-meter annealing furnaces, pickling tanks, ultrasonic eddy current integrated machines and physical and chemical laboratories, ensuring a comprehensive production process. The bending machine has a maximum thickness of 60MM and a length of 12 meters, which improves accuracy and versatility.

To ensure the quality of welded pipes, MTSCO follows a meticulous quality control process. Full-time quality inspectors supervise the entire production process before, during and after production, and guarantee 100% shooting of all welded pipes.

MTSCO's dedication to quality is reflected in its various certifications, including ISO/PED/AD2000. These certifications underscore adherence to stringent industry standards, giving customers confidence in the quality and reliability of MTSCO's welded pipes.

Quality Control Method：

First, secondary inspection of raw materials

Our raw materials come from large factories such as Baosteel, Tisco,TSINGSHAN, Eastern Special Steel... 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

MTSCO welded pipe is mainly formed by rolled plate (RBE) and bending, and the welding adopts PAW+GTAW. The whole process is automatic welding, which makes the welding efficiency increase and the weld seam more full and stable. Huxin's welded pipes have been upgraded in traditional technology, solving the problem of non circular welds in large size welded pipes, and use the 12-meter annealing furnace to make the annealing of the pipe more complete.

Each process 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 pipes, including routine appearance, PMI, size, quantity, and other inspections. At the same time, we also conducts mechanical testing, hardness testing, X-ray test, UT, ET, HT and other tests. Hydrotesting can test pipes with a maximum OD of 630mm, and we also perform 100% X-ray testing of welds.

In addition, we also accept third-party inspection, such as SGS, TUV, and BV.
