Q:Why can the air conditioning connection be made of copper tube? How about rubber tube and aluminium pipe? Please heroes pointing for the dishes.
The pressure of the aluminum pipe is relatively small. "Again, when the aluminum pipe is too soft, it is easy to be flattened.".. Rubber tubes will decay if they are used! Withstand pressure is also high!
Q:There are several ways to connect the built-in rubber stop
Is the cold adhesive rubber zhishuidai special cold glue, overlapped by the waterstop joints with grinder grinding section to 5~10 cm, glue can be compacted, has high strength, fast solidification has the advantages of convenient, time-saving, can meet the general engineering quality requirements.
Q:Is the installation of submersible pumps mandatory for the installation of flexible rubber joints?
According to the design requirements, choose whether the installation of rubber joints, Kannami Masashige water supply equipment Co., Ltd. is specializing in the production of rubber joint manufacturers, products and technical advice
Q:Method for inserting glass tube into rubber tube when assembling instrument
The sleeve method of different outer diameter glass tube should be determined according to the size of the outer diameter. If the outer diameter of the two tubes is not big, then the rubber tube with the same inner diameter can be connected. When connecting to the rubber sleeve in the larger outer diameter glass tube, the specific method, with a diameter from one end of the rubber tube of the same stick (such as chopsticks) inserted into the connection end to the rubber tube, rubber tube set in reverse, then the larger outer diameter glass tube against the wooden stick. The rubber hose forward turning sleeve on a glass tube, stick out.
Q:Do you need a hose connection to connect the ventilation pipe to the exhaust fan? Under what circumstances? Under what circumstances?
Must be added, never heard without the place, the wind turbine operation produces vibration, and galvanized sheet steel pipe is fixed at a certain place, if not, fan vibration, wind pipe vibration, the wind tube life are not long.
Q:What's the rubber sleeve of the expander?
Rubber joint called flexible rubber joint, soft rubber joints, rubber flexible joint, flexible joint, shock absorber, shock absorber, shock absorber pipe throat, is a kind of high elasticity, high air tightness, pipe joint resistance to medium and climate. The product uses rubber elasticity, high air tightness, medium resistance, weather resistance and radiation resistance etc., using polyester cord fabric skew high strength, strong stability and the hot and cold composite, after high pressure, mold temperature and curing.
Q:What's the difference between the rubber hose joint and the stainless steel hose joint?
1, high water use of this product, the pipeline must be fixed or fixed support bracket, otherwise the product should install anti pull off device. The force of fixed support or bracket must be greater than the axial force, or should install anti pull off device. And because the metal hose pressure resistance better, do not need to install.2, you can choose to use according to their working pressure: 0.25MPa, 0.6MPa, 1.0MPa pipe, 1.6MPa, 2.5MPa, 4.0MPa of the flexible rubber joint, high pressure pipeline equipment, we recommend that customers choose chungha brand stainless steel metal hose, according to the different use of the environment and the size, our biggest can withstand up to 300KG, customers can also ease of use.
Q:The difference between silicone tube and rubber tube
The main performance of the rubber tube: rubber tube is non-toxic, environmental protection, physical inertia, UV resistance, ozone resistance, resistance to high temperature (-8 to 300), high transparency, strong resilience, resistant to compression permanent deformation, oil resistance, impact resistance, acid and alkali resistance, wear resistance, flame resistance, voltage, conductive properties.Scope of application: supporting electrical appliances, electronics, furniture, equipment, toys, hardware, medical equipment, sporting goods, audio, lighting, machinery, automobile and other industries.
Q:How do you get the joint of the plastic pipe?
It adopts electric melting connection, which is suitable for PE water supply pipeline with big caliber inside and outside.
Q:What is the essential difference between natural rubber and three yuan ethylene propylene rubber?
The strength of natural rubber in the elastic material, natural rubber, rubber, rubber, vulcanized rubber with higher intensity. The tensile strength of uncured rubber is called Green strength, and the Green strength of natural rubber is up to 1.4~2.5Mpa. The proper Green strength is necessary for rubber processing and forming. The tear strength of natural rubber is also higher, up to 98kN/m, and its abrasion resistance is better. The reason for the high mechanical strength of natural rubber is that it is self reinforcing rubber. When stretched, the macromolecule chains tend to form crystals in the direction of stress.
