The overhaul of the expansion joint of the heating pipe is best carried out in the non-heating season, which is commonly called summer or during the heating outage. This is because:
Safety Factors: Maintenance during non-heating periods can avoid the risk of burns caused by high-temperature hot water or steam to workers.
System shutdown: The heating system is out of operation during the non-heating period, so that it can be disassembled, inspected and repaired more conveniently without affecting the normal heating demand of users.
Reducing Impact: Overhauling during non-heating seasons minimizes the impact on users' lives, when there is no heating demand.
Preventive maintenance: Using this time for preventive maintenance and inspections can ensure that all equipment is in good operating condition before the start of the next heating season, thereby reducing the probability of emergency failures.
Planning Arrangements: Non-heating periods provide heating companies with ample time to plan and implement necessary overhaul work and can coordinate resources and personnel when needed.
In terms of specific dates, if the general climatic conditions in the northern hemisphere are followed, the non-heating season roughly corresponds to between April and September each year. However, the exact optimal maintenance time depends on the local climate conditions, the specific heating cycle and the operating plan of the heating company. For example, some locations may complete overhauls in late spring or early summer to allow enough time to respond to possible problems and be fully prepared.
