Monel 400 Flanges

We are also manufacturer, supplier and exporter of Monel 400 (werkstoff nr. 2.4360) Forged Flanges, Plate Flanges, Big Diameter Flanges as per customers drawing or specification.

We are Manufacturers, Supplier and Exporters of Monel 400 Flanges. These Monel 400 flanges are used with stub end or daft which is butt welded to the pipe with the flange loose behind it. It implies the stub end or daft always makes the face. These flanges are designed to comply with International standards and specifications. Monel 400 offers about the same corrosion resistance as nickel but with higher maximum working pressures and temperatures and at a lower cost due to its superior ability to be machined.

Monel 400 material is a nickel-copper alloy (about 67% Ni – 23% Cu) that is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. Alloy 400 is a solid solution alloy that can only be hardened by cold working. This nickel alloy exhibits characteristics like good corrosion resistance, good weldability and high strength. A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters, and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions. This nickel alloy is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. As would be expected from its high copper content, alloy 400 is rapidly attacked by nitric acid and ammonia systems.

We are catering to provide our clients with a highly qualitative range of Monel Flanges that are fabricated using quality raw material and are available in various grades and dimensions. These products are known for the excellent quality. Our wide range of Monel flanges includes Monel Long Weld Neck Flanges, Monel Weld Neck Flanges, Monel Socket Weld Flanges, and Monel Slip on Flanges, Monel Blind Flange, Monel Screwed Flanges, Monel Lapped Joint Flanges, Monel Reducing Flanges and Monel Spectacle Blind Flanges.

We fabricate and supply monel alloy flanges which are fabricated using graded raw material in the production process. These precision engineered monel alloy flanges are durable, corrosion resistance, oil & temperature resistance and have high tensile strength. These are used with stub end or taft which is butt welded to the pipe with the flange loose behind it. It implies the stub end or taft always makes the face. The lap joint is ideal for low pressure applications as it is easily assembled and aligned. These can be supplied without a hub and/or in treated, coated carbon steel in order to reduce cost.

Fabrication and Heat Treatment

The machinability of MONEL 400 is difficult as it work-hardens during machining. The conventional machining techniques used on iron alloys may be used for this alloy. Welding methods including gas-arc welding, metal-arc welding, gas-metal-arc welding and submerged-arc welding are recommended on this alloy. Cold working may be done using soft die materials for better finishing.
