Q: The small hose attached to the grease gun is coarse or fine at the joint: For sealing, according to the maze principle, the smaller the pitch, the number of threads, that is, the more layers, the better the sealing effect, not easy to leak oil, significantly better than the rental thread.

Q: What is the method of making large diameter rubber joint?: There are three ways to apply large diameter flanges:First, raw material steel plate, through the template blanking: 1/4, 1/6, 1/6, and then welding lathe processing, drilling.Second, hot rolled flange blank, then lathe, drilling.Third, cold roll flange blank, steel plate into strips, cold roll machine, roll round, lathe, drilling machine processing.

Q: There are several ways to connect the built-in rubber stop: The built-in rubber sealing belt shall be an embedded rubber water stop belt, which is also called a buried rubber water stop or a middle rubber water stop belt.

Q: Latex tube, rubber tube, silicone tube, which three of the best tightness?: Ding Ji rubber: usually used as a silicone hose material used, in general, the sealing ability of silicone hose is better than the rubber hose. So, in life or in the industry need to seal the tube will take into account the silicone hose.

Q: The difference between hose and rubber tube: Rubber tube: characteristics of rubber tube has physiological inertia, UV resistance, ozone resistance, resistance to high temperature (-80 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. In fact, silicone hose is also a rubber tube, resistant to oil, heat.

Q: What are the materials used in rubber joints? What are their advantages?: Material has ordinary natural rubber, three yuan ethylene propylene (EPDM), nitrile and so onTo choose a different material, it depends on what kind of medium to go

Q: Why should the water stop strip be joined by heat instead of superposition?: Lap joint of rubber water stop belt is lap joint, this method is not allowed in engineering, glue glue and do not use overlay. In the case of splicing, it is equivalent to not doing any treatment at the joint. In the process of pouring, the sealing strip is prone to roll and twist.

Q: Single ball chloroprene rubber flexible joint, Shanghai Song Jiang rubber ball joint manufacturer where?: It is divided into 3 kinds: flange type, fixed flange type and thread type by connection. The structure can be divided into 5 kinds: single sphere, double sphere, different diameter body, bent sphere and wind pressure coil.

Q: What are the standard numbers for hose couplings? What standards are they used to accomplish?: The general hose inside and outside the adhesive layer material with natural rubber, styrene butadiene rubber or butadiene rubber; hose with chloroprene rubber, nitrile rubber; acid and alkali resistant, high temperature resistant hose with ethylene propylene rubber, fluorine rubber or silicone rubber etc..

Q: What kind of material does hose screw protection cover have? What are their advantages and disadvantages?: Hose cover is usually made of nylon or polyethylene
