High Clean and Bright Stainless Steel Control Line Tubing 100% Length Is Hydrostatic Tested

Product Description:

Our tubing products for the oil & gas industry have reached astonishing performance in some of the most hazardous subsea and downhole conditions. We have an impeccable record when it comes to meeting the set quality requisites of the oil and gas sector.

Meilong Tube manufactures coiled tubing in diverse materials resistant to corrosion such as stainless steel and nickel alloys. We have several years' expertise in the oil and gas domain, from the technical evolution in 1999, such as the subsea developments, up to the current deepwater complex issues.

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.

• Excellent resistance to 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

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.

Technical Parameters:

The seamless and floating internal plug redrawn tubing, supplied in the annealed condition with continuous length without orbital joint welds, is made with Alloy UNS N08825. Its Outer Diameter (O.D.), Wall Thickness (W.T.), Working Pressure, Burst Pressure, Collapse Pressure and Test Pressure are listed in the following table:

It should be noted that, the values in the table refer to the theoretical burst pressure based on minimum wall thickness, and minimum tensile strength, while the theoretical collapse pressure is determined by minimum wall thickness, and minimum yield strength. Furthermore, the Pressure rating is applicable at 100°F (38°C), under neutral and static conditions.

Applications:

Chemical Processing is a contemporary industry that utilizes various methods for the synthesis, manufacture, and transformation of a wide variety of chemical substances. Industries such as pollution-control, oil and gas well piping, nuclear fuel reprocessing, acid production, and components in pickling equipment like heating coils, tanks, baskets, and chains use these chemical processing techniques for a variety of operations.

Pollution-control is the practice of reducing pollution and hazardous substances in the environment. Utilizing modern chemical processing techniques, a range of lightweight and space-saving methods to collect pollutants and break them down into their more basic components are employed, making them less hazardous and more easily dealt with.

Oil and gas well piping and nuclear fuel reprocessing require a specialized form of chemical processing, often composed of more costly and complex processes. By utilizing specialized methods such as high-temperature heat treatment and corrosion- resistant coatings, these heavy-duty operations penetrate through difficult geographies, such as salt deposits, tropical jungle climes, and the deepest ocean depths.

Pickling equipment components, such as heating coils, tanks, baskets, and chains, often require an aggressive form of chemical processing known as pickling. This technique is used to remove contaminants from the metal surface, toughen it, and create a more resistant surface. Acid production also employs a unique form of chemical processing, utilizing a variety of compounds to create and synthesize some of the most corrosive and hazardous materials on Earth.
