Manufacture of stainless steel flux cored wireThe manufacturing process control of flux cored wire is very strict. As the molten filler metal comes from the steel sheet and the components contained in the flux, the size and chemical components must be carefully checked before manufacturing to ensure the quality.Due to the limited internal space of the welding material, the size of the flux particles becomes more important.

The utility of stainless steel flux cored wire is particularly MAG welding, MAG welding has the subsequent characteristics1) Compared with manual welding, welding speed can be advanced 2-4 times, its welding efficiency is as much as 90%(stainless steel electrode only 55%)2) to the current, voltage adaptation range, welding conditions are easy to set, easy to conduct semi-automatic and automated welding. 3) Good slag removal, welding pass surface gloss. In addition, the splash is very small, the arc stability is good, X-ray qualified.

Features of Flat Welding FlangesWhen welding flat welding flanges, only one side welding is required, and there is no need to weld the inner port of the pipe and flange connection. The welding installation of butt welding flanges requires double-sided welding of the flanges. Therefore, flat welding flanges are generally used for low and medium pressure pipelines, and butt welding flanges are used for the connection of medium and high pressure pipelines. Butt welding flanges are generally at least PN2.5MPa. Butt welding is used to reduce stress concentration.

About why wires and cables are twisted:1. Copper wires of different specifications and different numbers are twisted together in a certain arrangement order and laying pitch to become a conductor with a larger diameterThis stranded large-diameter stranded conductor is softer than a single copper wire of the same diameter, and the resulting wire has good bending performance and is not easy to break during a swing test.

The specification of the pattern plateIn fact, its specifications are mainly composed of thickness and width.

Laying points of stainless steel elbow in pipeline:1. In order to reduce the heat loss of the stainless steel elbow and prevent thermal deformation, the buried depth of the pipeline should be greater than 1.2 meters. (calculated from the top of the pipe). The burial depth in alpine regions should be appropriately deepened. At the same time, all pipes should be avoided to be laid below the water table.2. For areas where the groundwater level is high or it is difficult to dig deep for other reasons, measures should be taken as far as possible to avoid water insulators before burying the pipes.

Implementation principleThreaded flange is a kind of non-welded flange, which processes the inner hole of the flange into pipe threads, and is matched with the threaded pipe to realize the connection. Compared with the flat welding flange or the butt welding flange, the threaded flange has the characteristics of convenient installation and maintenance, and can be used on some pipelines where welding is not allowed. Alloy steel flanges have sufficient strength, but are not easy to weld, or the welding performance is not good, and threaded flanges can also be selected.

Structural features:Threaded flanges manufactured in accordance with ASME B16.5 are similar to sliding flanges, but the holes shall have tapered pipe threads in accordance with ASME b1.20.1. The thread shall be concentric with the axis of the flange opening, and the alignment deviation (perpendicular to the flange face) shall not exceed 5mm per meter. Threaded flanges are NPs 1 / 2 to NPs 24 in size and pressure classes are 150, 300, 400, 600 and 900. The sizes of class 1500 and 2500 are NPs 1 / 2 to NPs 2 - 1 / 2.Class 150 threaded flange has no counterbore.

Loose flange: This kind of flange is often used in the case where the medium temperature and pressure are not high and the medium nozzle is highly corrosive. The loose flange is generally used in combination with the flanging short joint, that is, the flange ring is loosely sleeved outside the flanging short joint, the pipe is butt welded with the flanging short joint, and the flange sealing surface is processed on the flanging short joint.In addition, there are flat welding ring and butt welding ring plate loose flange.
