Experts describe how compressed air pipes are welded

Compressed air pipeline said that the pipe flange welding has flat welding, butt welding and welding and other forms, specific see "hg20605-97" steel flange welding standard has a lot of, specific see you need what kind of standard to match, GB/ t9119-2000 plate type flat flange standard, HG/ t20615-97, general operation is the pipe to insert flange is probably; The thickness of the flange 3/1, do not insert the flange in the practice is between the flange and the pipe with a gap of 1 -- 3 mm welding.

Dalian compressed air pipeline according to the material selection of the pipeline suitable flange material, such as stainless steel pipeline is definitely not allowed to choose carbon steel flange; According to the nominal diameter (DN) of the pipeline and the nominal pressure (PN) of the whole pipeline system, the American standard system and the European standard system are basically adopted for pipe flanges in the world. According to the specific working conditions, choose the flange structure form: such as neck flat welding, looping flange, sealing surface form has protruding surface, full plane, concave and convex surface. For non - standard parts, according to the flange specification design procedures for design and manufacture.

The welding quality of pipeline welding machine is determined by many factors, the next small make up for you to briefly introduce. Workers with different attitudes affect the welding quality of pipeline welding machine. So said, the reason is that personnel engaged in this work, in their attitude toward work is different, some people are cautious, they will be in a serious and responsible attitude to pipe welding machine operation, while others would renege on using procedures, according to their wishes to use the machine, welding quality is not very good.

The quality and performance of pipeline welding machine will also affect the quality of welding. This machine has good and bad, some of the performance is not very stable, so their unstable performance will indirectly affect the quality of welding, resulting in the welding effect is not very ideal.

In the early stage of use of any equipment, the first advantage to be grasped is very critical. For example, for pipeline repair, the application of this material is basically in various industries and daily life, so the nature of this component in current life is very critical. According to the recent period of time since the damage status of connected devices, its professional operation personnel also summed up a truth, that is easy to damage the equipment basically are not getting more professional maintenance, because of long time application, will certainly affect good applicability of a device, therefore, the application of business need to learn professional maintenance method, for the patch on the one hand, the introduction of the pipeline equipment is.
