Maintenance method of welded pipe equipment

Welded pipe equipmentThe welding temperature is an important parameter for the production of welded pipe. The quality of high-frequency welded pipe mainly depends on the quality of the weld, and the welding drawing is the key factor affecting the quality of the weld. Therefore, controlling the temperature has a great influence on the welding quality. In the traditional high-frequency welding process, the welding temperature control is mainly based on the experience of the field operator.
It is difficult to be timely and accurate. If the welding temperature is too high, it is easy to cause excessive combustion of the weld and form perforations. If the temperature is low, the weld will not be able to penetrate, and skip welding may occur, which will affect the quality of the weld and cause residues. Inferior products not only affect the production efficiency of the product, but also constitute a waste of raw materials.
Common maintenance methods:
1. Regular lubricationWelded pipe equipmentParts that need to be lubricated. Use professional lubricants for lubrication and do a good job of rust prevention.
2. Do a good job in the daily inspection of welded pipe equipment, check whether all pipes are normal, and truthfully record the status of welded pipe equipment. If there are hidden problems in the welded pipe equipment, please repair it in time to prevent the normal use of the following. In the course of use.Welded pipe equipmentGalvanizing is a better way to extend its service life. The surface of the steel pipe must be pretreated before galvanizing. The pretreatment usually includes degreasing (degreasing is to remove grease and dirt on the surface of the black pipe to avoid affecting the effect of pickling. It can be achieved by burning or alkali washing to achieve general alkali washing) water washing, acid washing, re-washing, etc., although alkali washing removes some stains, however, the stains targeted by pickling and alkaline washing are different. The purpose of pickling is the scale on the surface of pipeline welding equipment. Pickling can be carried out at room temperature, with less metal corrosion and less hydrogen absorption. Because the possibility of contaminating carbon black residues is very small, pickling will produce oxides, the deep angle is large, it is easy to remove, and it has no effect on galvanizing, so pickling is more suitable for galvanizing.
