Discussion on the Application of Rubber Hose Pipe in Chemical Industry

Rubber hose pipes have become an indispensable accessory in the chemical, petrochemical and pharmaceutical industries, as well as in the transportation and production of automobiles, tankers, tankers and ships.


Such as high temperature, low temperature, wear, bending, folding, pulling, pressing and chemical corrosion. However, these harsh conditions and improper methods of users have always been a serious problem.


1. Inspection and delivery of rubber hose pipes in the chemical industry


Rubber pipes play a role in connecting equipment, machines or instruments, and can also transport various liquids according to their structure and design. Therefore, rubber hose pipes must be strictly inspected after being manufactured, and the main characteristics of the hose must also be tested. Monitor and standardize.


In order to meet all the requirements, the chemical industry rubber hose manufacturing plant has assembled a huge quality inspection process line from raw materials to finished product delivery, and established test statistics and qualification certificates through quality inspection.


The inspected hose must be delivered with an inspection record sheet, which records the structure of the hose and the date of production, inspection and quality monitoring. In order to be responsible for the user, it is also necessary to record the problems that occur in the production process, especially the accidents and failures that are easily encountered in the process of transporting steam and corrosive liquids.


Nonetheless, the person in charge of safe work in the chemical industry has found that due to improper user methods, rubber hose pipes are not compatible with certain conditions of use and liquids. Even if no damage to the hose is observed when delivering such products, it is important to understand why products containing solvents or cleaning agents can quickly damage the inner and outer layers of the hose.


In addition, hoses that require manual or automatic operation under pressure or high temperatures should only be performed if it is determined that the hose can withstand folding, twisting, shock and abrasion.


In addition to the selection of permeability, effective pressure and diffusivity of the rubber pipe, the selection of better service conditions such as length variation and standard diameter is also important. And the time and service life of the industrial hose in contact with the liquid must be accurate, all these parameters are fairly easy to determine, and it is also necessary to know whether the hose can withstand vacuum (intake) or pressure.


2. Select the appropriate rubber hose according to the needs of use


Because there are many industrial hoses to be used under vacuum, in this case, the industrial rubber hose should be reinforced with steel wire or other high modulus materials. Manufacturers and marketers of hoses for the chemical and petrochemical industries must be able to advise and answer the specific requirements of each type of hose to users.


In order to help users choose hoses and meet the various requirements of users, manufacturers of industrial rubber hoses have drawn some charts corresponding to the hoses. But this still can not meet the requirements of users, a better way is to often negotiate with the manufacturer or conduct actual tests, these charts can only serve as a reference for users.


3. The installation of rubber hose fittings


The size of the pipe joint must be consistent with the size of the hose, otherwise the hose may be damaged, so it must be installed by professionals. To check the quality of the installation, professionals can perform pressure and conductivity tests.
