Widely used for transporting fuel, oil, liquid vapor, hydrocarbon products such as gasoline, diesel. kerosene, crude oil, etc., positive and negative pressure does not affect use Static design.

2,Appearanceinspection:

• 1.Check for any dents or distortions in the pipe body.
• 2.Check for corrosion, wear, and looseness of the spira stee wire.
• 3. Check for any abnormal phenomena such as leakage, cracks, corrosion, deformation, etcin the joint.
• 4. Check for leakage in the pipe body and excessive wear of the reinforcement layer.
• 5. Whether the inner laver of the pipe has been corroded and detached.lf the hose exhibitsany of the above phenomena or other abnormal features, it must be stopped from use.

3,Stress testing:

• 1. Clean the hose thoroughly and test whether there is conductivity between the two ends ofthe joint (non-conductive is prohibited from proceeding to the next step of testing)
• 2. Place the hose flat on a test bench that allows the hose to move freely.
• 3. Fill the hose with clean water, seal the joints at both ends, and empty the air inside the hose
• 4. Apply pressure to 1.5 times the maximum working pressure of the hose, and there should beno leakage in the hose After the hydrostatic test, the water should be removed to keep theinside of the pipe dry.
• 5.Before, during, and after the water pressure test, the conductivity between the two joints ofthe hose should be tested simultaneously.
• 6. The hose should undergo a comprehensive inspection at least once every 6 months, and thetest data should be recorded and saved during the testing process.
• 7. Composite hoses are made of thermoplastic elastomer hoses, and there will be a certainamount of elongation during the pressure testing process, which is a normal phenomenonand cannot be used as hosesThe criteria for continued use.

4,Storage:

• 1. Clean before storage and ensure that the inside of the tube is dry (please request cleaning methodsfrom Hongtai).
• 2. lf not used for a long time, it should be stored in a dry room with a flat surface and light shielding.
• 3.When storing hoses outdoors, shelters should be set up to minimize long-term exposure to sunlight

5,Repair:After the Hongtai hose is damaged, it may be possible to repair it, but it must be carried out by anapproved engineer.

6,Waste disposal:
The inner laver of some of Honatai's chemical composite hoses is made of fluoropolymer PTFEwhich generates HF COF2 when the normal operating temperature exceeds 205 ℃~260 ℃cToxicgas. When using hoses or handling related waste, it is necessary to comply with the laws andregulations of the local country and region, which should be carried out by professionaldepartments or recycled by Hongtai,Burning and discarding are prohibited.
