Characteristics of Tee in Stainless Steel Pipe Fitting

Mar. 12, 2020

There are many types of stainless steel pipe fittings, which refers to alloy steel that contains 13% or more of Cr and is stainless in the atmosphere. There are austenitic stainless steel, ferritic stainless steel, martensitic stainless steel and so on. Stainless steel is generally non-magnetic. Stainless steel three-way control fused holes are large and small, and the shape is the key to the double-sided forming of the bottom welding. The carbon steel tee supplier will share with you:

There are many types of stainless steel pipe fittings, which refers to alloy steel that contains 13% or more of Cr and is stainless in the atmosphere. There are austenitic stainless steel, ferritic stainless steel, martensitic stainless steel and so on. Stainless steel is generally non-magnetic, austenite is non-magnetic, but ferrite is, but it is also relatively weak. Different stainless steels have different resistance to corrosion, and they have different resistance to different media.

Stainless steel pipe fittings supplier believes that the difference between carbon steel and stainless steel pipe fittings is generally believed that the first is the corrosion resistance. However, in practical applications, stainless steel has irreplaceable effects of other steels due to its excellent various properties, such as some high temperature resistant stainless steels, and the surface properties of stainless steel are mostly used for decorative materials, and the excellent mechanical properties of stainless steel Make it applied in various manufacturing industries.

Austenitic stainless steel due to the addition of high chromium and nickel in the steel (containing about 18% chromium, Ni above 4%), the internal structure of the steel presents a structure called austenite, this structure is Without magnetic permeability, it cannot be attracted by magnets. Commonly used as decorative materials, such as stainless steel pipes, towel racks, tableware, stoves, etc.

Martensitic stainless steel is used to make stainless steel for knife and scissors. Because knives and scissors have the function of cutting articles, they need to have sharpness and sharpness and hardness. This type of stainless steel undergoes structural transformation through heat treatment, and can only be used for knife shearing after increasing hardness. However, the internal structure of this type of stainless steel is tempered martensite, which has magnetic permeability and can be attracted by magnets. Therefore, it cannot be simply stated whether there is magnetism or not.

Introduction of stainless steel tee:

1. Start the arc on the bevel surface, and immediately retreat to the starting point of the slope root (usually 10mm before the 6 o'clock position). When you see the beginning of melting, add welding wire quickly, so that the welding wire and the base metal fuse all the way. It can be seen that the melt and slag flow into the pipe evenly through the groove to form a molten hole; the welding torch makes a small zigzag swing and moves up a bit faster, the welding wire does not leave the argon protection, and it must be attached to the blunt edge of the groove At the gap, the intermittent wire feeding method is adopted, one by one, one drop at a time, and the drop is filled into the molten pool.

2. During the welding process, short arc operation should be maintained; the handle should be stable, and the wire feeding should be clean and sharp. Pay attention to the gap between the welding wire and the tungsten electrode to prevent "tungsten". Otherwise, it must be cleaned and then welded again.

3, stainless steel tee control fused holes are large and small, the same shape is the key to the double-sided forming of the bottom welding.

4. During the welding process, the welding wire should be evenly melted, and a thin layer of slag should be evenly penetrated into the nozzle to protect the weld seam. This is why the flux-cored welding wire is used.

5. After the stainless steel tee is welded, the slag will fall off by hammering. The slag in the pipe can also be dropped by compressed air or water flushing, so as to obtain a beautiful golden yellow weld in the pipe.
