What should pay attention to when choosing a steam hose
The daily protection and maintenance of steam hoses is an important basis to ensure and prolong service life and prevent incidents. Steam hose operators carefully do the daily protection and maintenance work of steam hose:
1. Often check the steam hose protection methods, to ensure that it is intact, reduce the corrosion of the pipeline surface;
2. The steam hose out of use should exclude the internal medium, and carry out replacement, cleaning and boring, if necessary, inert gas protection. The outer surface should be painted protection, there is heat preservation pipe pay attention to the insulation material is intact;
3. Electrostatic bonding and grounding devices should be kept in good condition and repaired in time if any damage is found;
4. Check the complete condition of the fastening bolts regularly, so as to be complete, not corroded, the thread is intact and the joint is reliable;
5. The safety valve and pressure gauge should be often wiped, to ensure that the activity is accurate, and on time to verify;
6. Pay attention to the oscillation of thehose. If abnormal oscillation is found, isolation of vibration source and strengthening of support should be adopted.
7. The operating mechanism of the valve should often remove rust and oiling, and operate regularly to ensure its sensitive operation;
8. Check the contact places of pipes and supports for corrosion and wear, find problems and adopt measures in time.
When designing a new steam distribution system, it is important to consider both flow rate and pressure drop because such considerations reduce the risk of using a steam pipe with a large diameter, which not only increases the cost, but also leads to more heat loss.
Using steam pipes with too small a diameter can easily lead to corrosion and increase pressure drop. Equipment use and steam requirements change over time, which may lead to failure fully utilize steam piping system and cause more heat loss.
However, in order to meet the change in demand for steam,the cost of system optimization is too high to be cost-effective. The most cost-effective measures are containment and shut down those extra steamhoses to reduce the loss of steam distribution.
