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.
This alloy is highly resilient with its following characteristics:
- 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
It can be used for a variety of purposes.
Technical Parameters:
The seamless and floating internal plug redrawn tubing is supplied in the annealed condition, which is without orbital joint welds in a continuous length. What's more, the theoretical burst pressure is based on the minimum wall thickness and the minimum tensile strength, and the theoretical collapse pressure is based on the minimum wall thickness and the minimum yield strength. The pressure rating is at 100°F (38°C) under neutral and static conditions, and the longitudinal welds are checked by UT inspection.
Below is an overview of data with regard to alloy UNS, O.D., W.T., working pressure, burst pressure, collapse pressure, and test pressure.

It includes pollution control, oil and gas well piping, nuclear fuel reprocessing, and components such as heating coils, tanks, baskets, and chains used in pickling equipment. It also involves acid production systems.
Pollution control requires specialized knowledge and experience to ensure that all operations are conducted with the utmost safety. Oil and gas well piping must be strong and reliable to withstand the high pressures and temperatures associated with these processes. Nuclear fuel reprocessing requires specialized handling procedures to ensure safety.
Components like heating coils, tanks, baskets, and chains used in pickling equipment must meet high standards. For example, they must be able to withstand the acid and temperature involved in the process. Acid production systems also need to be designed to be resistant to corrosion and safe for human use. Support and Services:Control Line Tubing technical support and service include: - Design, installation, and maintenance of control line tubing systems
- Testing and troubleshooting of existing control line tubing systems
- Replacement of defective or damaged control line tubing components
- Provide operational and technical support as needed
- Provide periodic inspection and maintenance of control line tubing systems
Packing and Shipping:Packaging and Shipping of Control Line TubingControl Line Tubing is packaged with extra care to ensure safe delivery to the customer. All tubing is inspected for defects prior to shipping and packed in heavy-duty cardboard boxes with internal protective foam padding. All packages are then securely sealed and labeled with the customer's name and address, as well as the number of units and product details.
The selected shipping method depends on the size of the shipment and the customer's location. Smaller packages are typically shipped via US Postal Service or UPS, while larger orders may be shipped via a freight carrier. All shipments are tracked and insured for added protection. |
