Installation and use of stainless steel pipe fittings

Stainless steel pipe fittings is a general term for a variety of stainless steel pipe connection workpiece, with easy installation, high performance, durable characteristics, widely used in a variety of pipeline construction and installation. So how to install stainless steel fittings do you know?

　　Stainless steel pipe fittings is a general term for a variety of stainless steel pipeline connection workpiece, according to the shape, use, connection can be divided into different categories. It has the characteristics of easy installation, high performance and durability, and is widely used in various pipeline construction and installation. Stainless steel pipe fittings can be divided into stainless steel tee, stainless steel flange, stainless steel head, stainless steel elbow, stainless steel cap, stainless steel head, etc.

Installation of stainless steel pipe fittings.

　　1. The arc is induced in stainless steel pipe fittings using the reflux method and the arc is collected using the full arc pit method. The induced arc should be carried out on the slope, and is not allowed to induce arc or hit the arc on the busbar surface of the pipe and fittings. Arc extinguishing process found in the cracks, porosity and other phenomena should be cleaned up in a timely manner.

　　2. When lifting, stainless steel pipe fittings should be separated from other metals to avoid direct contact. Can use padded wood, rubber sheet and other non-metallic materials for isolation.

　　3. When stainless steel pipe fittings are continuously welded, the temperature shall not exceed 60 degrees Celsius. In the positioning process, the weld seam should be protected internally by argon filling. Cutting can not use ordinary grinding wheels, should use special grinding wheels for stainless steel pipe fittings or plasma cutting. Shared from Cangzhou Aerospace Pipeline.

　　4. Stainless steel pipe fittings piping and non-stainless steel piping, pipe fittings connection, welding butt joint priming welding before, should be filled with argon gas inside the pipe and the inner cavity, before tungsten arc welding. After welding, the weld at the joint should be pickled and passivated.

Use of stainless steel pipe fittings.

    W-B75 Wechsler hardness tester can be used for stainless steel pipe fittings diameter of 6.0mm or more, wall thickness of 13mm or less annealed stainless steel pipe fittings wood, very fast and simple, suitable for stainless steel pipe fittings wood for rapid non-destructive qualification inspection. Stainless steel pipe fittings, stainless steel pipe fittings with an inside diameter greater than 30mm, wall thickness greater than 1.2mm, with Rockwell hardness tester test HRB and HRC hardness. Stainless steel pipe fittings with a diameter greater than 30mm and a wall thickness less than 1.2mm, the application of surface Rockwell hardness tester for HRT or HRN hardness testing. Stainless steel pipe fittings with an inside diameter of less than 0mm and greater than 4.8mm should use a pipeline special Rockwell hardness tester for HR15T hardness test. When the inner diameter of stainless steel pipe fittings is greater than 26 mm, you can also use Rockwell or surface Rockwell hardness tester to test the hardness of the inner wall of the pipe.
