The elbow at the top of the cement tank refers to the bent part at the top of the cement tank. If the elbow at the top of the cement tank is often perforated, it may be caused by many reasons.

One possible reason is that the design of cement tank is unreasonable, which leads to the weak elbow structure and cannot bear the weight of cement and internal pressure. Another possible reason is that improper use of cement tanks, such as excessive compression or excessive inclination, can also lead to elbow perforation.

If the elbow at the top of the cement tank is often perforated, it is suggested to check the design and use of the cement tank and consider replacing it with a higher quality cement tank to ensure its normal use.
