Nickle Alloy Flat Welding Flange Incoloy 28 Nr. 1.4563 Petroleum Equipment Reactor

Nickle Alloy Flat Welding Flange Incoloy 28 Nr. 1.4563 Petroleum Equipment Reactor

Nickle Alloy Flange, also known as a flange rim or flange, is a part that connects pipes to each other at the ends, and it is also used on equipment inlets and outlets for connecting two pieces of equipment, such as a reducer flange. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolt, which together form a combined sealing structure.

Welding Process:

• Required Equipment: A set of manual arc welding equipment, one handle-type angle grinder, one electric air hammer, and one straight edge.
• Folding Welding Preparation: 1. Check and adjust the equipment to ensure normal operation; 2. Prepare φ4.0 J402 welding rods, which are preferably dried at 300°C - 350°C for one hour.
• Folding Welding Process: 1. Assemble the cone and the large flange according to the drawing requirements, then divide the large flange into 8 equal parts; 2. Welding due to the thicker flange and larger groove, the use of segmental symmetrical, multi-layer welding is adopted.
• Folding Welding Quality Requirements: The weld strength must at least match the strength of the base material. The weld surface should be flat and smooth, without defects such as burn-through, porosity, welding leaks, slag inclusion, undercutting, or incomplete welding. The weld reinforcement height should be less than 2mm.
• Folding Notes for Attention: 1. When welding the base layer, always use J506 welding rod manual surfacing and welding with a small current. Strictly follow the welding process; 2: After welding each position, use a level to check the deformation of the flange plane; 3: While welding, use the air hammer to strike the weld to eliminate stress.

INCONEL ALLOY 28: (UNS N08028) is a highly corrosion-resistant austenitic alloy offering resistance to a variety of media. The alloy resists attack in reducing media due to its contents of nickel, copper and molybdenum and is resistant to oxidizing species due to its high level of chromium. Alloy 28 offers resistance to general, localized and stress-induced corrosion by chlorides and hydrogen sulfides. Thus, it is widely used in oilfield applications. Tubes are cold worked to high levels of strength for downhole service in deep sour gas wells. With its excellent combination of strength and corrosion resistance, alloy 28 also finds applications in the process industries. It is especially useful for handling phosphoric acid. Due to its resistance to chlorides, alloy 28 tubes may be used in the marine industry for seawater-cooled heat exchangers.
