One of the reasons for the leakage of heat preservation pipe equipment during installation and trial run is that the head bolts must be tightened again before the head is heated without feeding. After the head is heated, the head will expand, resulting in a narrow gap between the parts of the head, leading to leakage. Two reasons, after feeding, if the head body leakage, should check the relevant parts of the head body has no trachoma.
Thermal insulation pipe production line material leakage in the production process, should check the head outside the heating coil heating ring and the inside of the machine head is heated to normal, if damaged, the body temperature is too low, extrusion pressure increase leading to head leakage, serious will put the head top bad, causing major losses, this point should pay attention to the production line personnel.
