How to maintain welded pipe equipment

Author:   Source:TENYES ELECTROTHERMAL EQUIPMENT CO.,LTD.   Date:2020-09-29 
Welded pipe equipment is the most important part in welded pipe production, so the maintenance of welded pipe equipment is very important in normal use, which is not only to ensure the normal production and manufacture, but also to prolong the service life of welded pipe equipment.
Common maintenance methods:
1. Regularly lubricate the parts of welded pipe equipment that need lubrication, select professional lubricants for lubrication, and do a good job of rust prevention.
2. In daily life, it is necessary to do a good job of spot inspection of welded pipe equipment, check whether all pipelines are in normal state, and keep a truthful record of the status of welded pipe equipment. If hidden dangers exist in welded pipe equipment, repair them in time to prevent affecting the normal use below. Galvanizing is the best way to prolong the service life of welded pipe equipment in use. Surface pretreatment must be carried out before galvanized steel pipe. Pretreatment generally includes degreasing (degreasing is to remove the grease and dirt on the surface of the black pipe, in order to avoid affecting the pickling effect, general alkali washing can be realized by combustion or alkali washing), water washing, acid washing and water washing again. Although some stains have been removed by alkali washing, the stains are different between acid washing and alkali washing. The purpose of acid washing is the scale on the surface of welded pipe equipment. Acid washing can be carried out at normal temperature, with less metal erosion and less hydrogen absorption, which is less likely to pollute the carbon black residue. Acid washing produces oxide, which is easy to remove and has no effect on galvanizing. Therefore, acid washing is more suitable for galvanizing.
