Technological equipment and process piping.
Consider the use of argon welding for the repair and installation of process piping.
Process piping, piping, which is being delivered and the removal of process fluids (media), to ensure the functioning of the enterprise, factory, workshop. These pipes are used in virtually all sectors of industry: chemical industry, food processing plants, breweries, pharmaceutical, agriculture, metallurgy, etc.
Pipelines can be executed from different materials: steel of medium-low, low-medium-high-alloy steels, titanium and its alloys.
The vast majority of steels used for the installation of process piping, stainless steel: AISI-304, 308, 316, 321, according to emission class: EN-1.4301, 1.4307, 1.4404,1.4878, as they provide a sufficiently high corrosion resistance for slightly aggressive media: product delivery systems, washer system for food and chemical industries, technological blocks and blocks of communication pipes and piping components, piping industry, and interplant intrashop pipelines, pipelines tying.
In the case of medium to high aggression (chemical plants using chlorine) - it is advisable to use tubes made of titanium and its alloys, or high-alloy steel, providing increased corrosion resistance to the applied environment.
For installation of process piping used appropriate supports, which are made by: GOST 14911-82, OST-94-36 83.Opory pipelines can be made of various materials, which is caused by the environment of their application.
The most affordable type of welding for the above works, is the argon-arc welding.
This welding technique is quite simple: In an inert gas - argon or helium, the arc burns. Electrode - a non-consumable, as it has a very high melting point, tungsten-electrode material.
Welder argonschik performs welding, the welding rod through the feed zone of fusion (welding bath). The welding process can occur as well without the feeding of filler material in the molten bath, this function takes on the metal tube - the base metal, and this way is called a pendulum-Pendel.
For high-quality welding of pipe joints must be:
A. Precise control of welding current and welding machine capabilities.
Two. The presence of mounting accessories.
Three. Experience welder - generating welding joint.
Pipes used for assembly, may have a different diameter - from 10mm to 1021mm. or more, different pipe wall thickness.
Accordingly - a pipe having a wall thickness of 2.6 mm can be welded without cutting edges, which in turn provides a welding filler material or not. Tubes with a wall thickness of 3 mm - welded to the cutting edges, that is - at a certain angle, cut off the end of the pipe-welding to provide access into the manipulation of the welding connection. Welding process, to ensure penetration, the formation of a continuous seam welding inside the compound (pipe .)
In order to ensure that the penetration, ie, quality of welding connections - requires a high level of preparation of the welding specialist.
