Large Diameter Suction and Discharge Hose is widely used in conveying crude oil, fuel oil, food oil, chemical solvent and liquefied petroleum gas. Has a good electrostatic export function.

Scope of application and maintenance of Large Diameter Suction and Discharge Hose

Large Diameter Suction and Discharge Hose is widely used in conveying crude oil, fuel oil, food oil, chemical solvent and liquefied petroleum gas. Has a good electrostatic export function. When transporting oil and flammable media, due to factors such as pressure, flow rate, friction, etc., the static electricity will be generated. If it is not exported in time, the consequences will be unimaginable. The product is supported and connected by the inner and outer armored double-layer steel wire, which has electrical conductivity and can be used. The scope of application of oil hoses: large, medium and small port terminals such as oil tankers, tankers refueling, oil tanker oil discharge, large, medium and small petrochemical refineries to transport oil and oil, large and medium-sized animal and plant refineries to transport refined oil, oil tankers to transport oil and oil, Railway train refueling, petrochemical oil storage and transportation companies, etc.

The utilization rate of Large Diameter Suction and Discharge Hose is very high, and it is widely used in petrochemical and other industries. What are the precautions for the use and daily maintenance of oil hoses?
Precautions for use and maintenance of Large Diameter Suction and Discharge Hose
Large Diameter Suction and Discharge Hose daily maintenance inspection should pay attention to the following items, if the hose meets one of them, it should be scrapped:
1. The appearance is dented or distorted.
2. The inner and outer steel wires move.
3. The outer steel wire is corroded or worn.
4. The joint is loose or leaking.
5. Use a multimeter or an ohmmeter to detect different paths at both ends of the hose.
6. The joint is corroded, worn or damaged by other external forces
Large Diameter Suction and Discharge Hose daily maintenance cleaning method
Large Diameter Suction and Discharge Hose should be cleaned after use, before testing or before long-term storage.
The cleaning method should be determined according to the environment and usage of the hose. During cleaning, one end of the hose should be grounded.
1. It can be cleaned with tap water, hot water, detergent, normal solution at room temperature or sea water. If seawater cleaning is used, after cleaning, drain the seawater in the pipe to prevent the hose from being corroded by seawater.
2. For hoses used to transport strong acid medium, the residual medium should be drained before cleaning to prevent frictional heat generation during cleaning.
3. There should be no residue in the hose for conveying colloidal medium after use, so as to prevent the hose from reacting when it is used next time. Nitrogen, steam or air can also be used to purge the hose, but the temperature should not be too high, and both ends of the hose are open to avoid damage to the hose.
