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.

Hastelloy C22, is a nickel-chromium-molybdenum alloy with enhanced resistance topitting, crevice corrosion, and stress corrosion cracking.This alloy is resistant to the formation of grain boundaryprecipitates, specifically in the weld-heat affected zone.This attribute makes alloy C-22 suitable for use in the as.welded condition.C-22 has outstanding resistance to both reducing and oxidizing media. Due to these corrosion resistant properties, alloy 22 can be used wherechallenging conditions are likely to occur. The alloy hasoeen proven to possess excelent weldabiity and highcorrosion resistance as consumable filler wires andelectrodes. Alloy C-22 also has proven results as a fillel wire in many applications. C-22 can easily be cold-worked because of its ductility.Cold-forming is the preferred method of forming. Coldworking requires more eneray during production because the alloy is stiffer than austenitic stainless steels. For comparison, a 0.28" thick sheet in the heat-treated at2050°F,rapid quenched condition, has an average olsencup depth of 0.49".

Round Bar, Loose Coil, Sheet, Plate, Tubing, Fittings

Applications

C-22 is used in severely corrosive media with high chlorideand temperature applications such as buffer solutions,active pharmaceutical ingredients (APl), fabric softenerscleaning supplies, and fish, soy and chili sauce.

General Data

Alloy C-22 is a great alternative when super austeniticstainless steels (AL-6XN®, 904L, and 254 SMO®) andduplex stainless steels (2205 and 2507)will not withstanoextremely aggressive media. This is because it is a nickel-chromium-molvbdenum-tungsten a oy with better overaresistance to uniform and ocalized corrosion than anyother Ni-Cr-Mo alloys such as Hastelloy C-276,C-4, ancalloy 625.

• No crevice and pitting corrosion, no product accretion.
• Highly corrosion resistant.
• Can pe cod-worked to enhance properties
