Nickel Alloy Tubing Hydraulic Control Line Close Dimensional Tolerance Continuous Length Without Orbital Welds 100% Leng
Product Description:
Meilong Tube manufactures high quality coiled tubing in a variety of forms, including seamless and redrawn, seam-welded and redrawn tubing. These products are made from corrosion-resistant austenitic, duplex, super duplex stainless steel and nickel alloy grades. They are commonly used in hydraulic power control lines, chemical injection lines, umbilicals, and instrumentation tubing for upstream oil and gas exploration.
Coiled tubing is available in outer diameters ranging from 0.125 inch (3.175 millimeters) to 1 inch (25.4 millimeters), and wall thickness up to 0.083 inch (2.108 millimeters). Lengths up to 65600 feet (20,000 meters) are available, and custom sizes can be accommodated. As more oil and gas extractions move into increasingly deeper and harsher environments, our goal is to ensure that these projects use the “right” corrosion resistant material for coiled umbilical tubing, enhancing safety and reliability.
Meilong Tube is committed to providing the most cost-effective tubing products, and this involves guaranteeing a comprehensive value-added chain in tubing production. This results in higher performance products and customer satisfaction.
Features:
Incoloy alloy 825 is a nickel-iron-chromium alloy with additions of molybdenum and copper. This nickel steel alloy’s chemical composition is designed to provide exceptional resistance to many corrosive environments. It is similar to alloy 800 but has improved resistance to aqueous corrosion.
It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. Alloy 825 is especially resistant to sulfuric and phosphoric acids. This nickel steel alloy is used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.
The qualities of this alloy make it an ideal option for many industrial uses. Some of its best characteristics include:
- Excellent resistance to both reducing and oxidizing acids
- Good resistance to stress-corrosion cracking
- Satisfactory resistance to localized attack like pitting and crevice corrosion
- Very resistant to sulfuric and phosphoric acids
- Good mechanical properties at both room and elevated temperatures up to approximately 1020° F
- Permission for pressure-vessel use at wall temperatures up to 800°F

The burst pressure is based on minimal wall thickness and minimum tensile strength and collapse pressure is computed from minimum wall thickness and the minimum yield strength. The pressure rating is specified at 100℉, neutral and static conditions. No internal valve, plug, pressure rupture disk or any other kind of flow restriction is included in the calculation.
