In order to use the steam hose safely, it is recommended to check the condition of the hose regularly, especially some hoses that have been idle for a period of time. In order to avoid unnecessary trouble, a simple inspection will not take long.
1. EXTERNAL DAMAGE AND WEAR
Steam is hazardous and steam hoses should not be used if there are signs of wear or damage on the cover. Kinking steam hose causes internal damage to the reinforcement which will reduce the service life and can be a cause of unexpected catastrophic failures as well. The hose should be inspected for damages and proper fitting installation before each use.
2. Pressure, Temperature and Vacuum
Do not use steam hoses (or other types of hoses), which do not reach the pressure and temperature of the connected system. Connect the hose to a system with a higher rated pressure or temperature than the hose, which will cause premature damage to the hose assembly. The steam hose is not designed to withstand vacuum, so it should not be used in systems with vacuum.
3. External Environmental Factors and Storage
Even high-quality hoses will be affected by some external environmental factors; sunlight, temperature changes, salt water, chemical and chemical vapors and pollutants will corrode the hoses, and the hoses must be replaced to a certain extent. All these factors should also be carefully considered when storing new or used hoses.
4. Install Correctly
In order to use the hose assembly safely and correctly, it is important to install the application correctly. The length of the hose between the two connection points is correct to ensure equal weight and pressure distribution. In order to reduce the possibility of kinking, a vertically downward opening facing downward outlet is ideal to reduce the pressure on the hose.
5. Clean the hose
Sand, dust, dirt and other foreign matter in or around the hose can also cause damage. It is important to remove the material before using the hose.
6. Preventive maintenance
A perfectly used hose assembly should be inspected during the installation of the correct fittings for damage, and a constant pressure test should be carried out at the rated working pressure twice a year. This ensures safe and reliable assembly even when using old hoses.
There are many standards and certificates for steam hoses worldwide. For example, in Canada, TSSA requires testing of steam hoses, joints and components. Before providing steam hose assemblies to customers in Canada, proper certification is required. In the United States and Europe, hose standards include RMA safety standards, ISO 6134-2A, NFPA for fire protection, and TS16949, ISO9001 and ISO14001 for quality.
