Q:Will the outside of the brake hose of the car burst apart?
If the brake oil pipe (you should be the brake hose) is best, I'd recommend replacing him
Q:What's the difference between the rubber hose joint and the stainless steel hose joint?
Rubber joints are widely used in chemical, construction, water supply, drainage, petroleum, light and heavy industries, freezing, sanitation, plumbing, fire fighting, power and other infrastructure projects. For example: with the pump, valve connection, vibration of the larger pipes, hot and cold changes frequently pipeline.No way, because it is loose summer, it is a well-known brand. Great. The general choice will definitely be good. Otherwise, all sorts of trouble in the later stage, it also can not stand.
Q:How can the hose of natural gas be connected to the water heater?
Both ends of the hose nut with inlet joint head directly said water heater, the key is the nut inside with sealing ring can not forget the good, but also to the right, after tightening will not leak, then good with soap and water leak, do not bubble. But you must point out that the safety requirements can not be connected to the general hose, should be connected to the hard tube (Bai Tieguan), temporary answer, we must pay attention to safety.
Q:In long-term high temperature environment, silica gel tube and three yuan ethylene propylene rubber hose which is good durability?
Others, such as three yuan ethylene propylene and nitrile rubber hose, are basically black. Long term use of plastics can cause fading and deformation. The chemical properties of silica gel are stable and the physiological inertia is good. They are very resistant to biological aging, have no rejection reaction with limbs, and have better anticoagulant properties.
Q:Method for connecting glass tube and rubber tube
Just one end of the glass, wet with water, and then rotate hard
Q:Is rubber tube harmful to drinking water?
There are drinking water standard rubber tube, ordinary hose can not be directly applied to drinking water, there is low toxicity!
Q:How can we prevent the aging of rubber tubes?
The second is the design of the structure of the rubber products (especially damping products), has a great relationship between aging and fatigue, should avoid stress concentration! If the product is good has been produced to prevent aging, more trouble! Can be sprayed on the rubber surface, spraying insulation polymer.
Q:SolidWorks how do you put rubber hose on the iron pipe?
This is to be made into an assembly. First, parts, iron pipes and rubber pipes are made separately, and then the assembly is made to fit together.
Q:Hydraulic hose joint configuration
Well control hose connector: composed of a core rod and sheathed and connected with the sleeve is characterized in that the outer surface of the core rod and the sleeve on the surface along the circumferential direction of the corresponding is provided with at least 1 slots with each other and clasp. The utility model has the advantages of high temperature resistance, high pressure and resistance to pull out of the rubber tube, and is especially suitable for the connection hose of the oil well drilling control device.
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
