Q: High pressure hose K type joints KJR32 and KJR31.5D what is the difference between ah, please give us a answer,: K type joint has the distinction between national standard and German standard. In general, 32 and 38 tubes are used more often. The joints used on 32 of the tubes are KJR32 and KJR31.5D. 38. The joints used on the tubes are KJR38 and KJR B40

Q: Do I need a shim for the flat metal hose joint?: If one of the two interconnected joints is one of those with a groove and a O ring, it would be better to put the O ring in it and seal it better.

Q: What is the essential difference between silicone tube and rubber tube?: Silica gel tube has high and low temperature (-60 ~ 200 DEG C), environmental protection, non-toxic, excellent heat aging, ozone aging resistance, light aging and aging resistance, soft, arc resistance, corona resistance.Silicone hose is the biggest feature of resistance to temperature changes of -60 degrees to 250 degrees, but the cost is very expensive, no requirement for the hose. Compression resistant silicone hose resistant to pressure can also be.

Q: What is the principle of communicating devices? What if the rubber tube is used as a connecting device to change the water for the fish?: The principle of siphon principle has long been known by the Chinese people for the discovery and application of siphon principle. Hong Straw manufacturing principle application of siphon, in ancient China called "sub", "partial" and "siphon" or "siphon". At the end of the Eastern Han Dynasty, thirsty for irrigation appeared. In southwest minority with a long curved bamboo festival to drink, but also the application of the physical phenomenon of siphon. The song "Ceng Gongliang Wujing Zongyao", making the Straw useful bamboo rainbow mountains spring bring down the record barrier. China ancient also uses siphon principle is made. A fire extinguisher is a necessary war in the city. The Song Dynasty Su Shi "dongpozhilin" Volume 4, recorded by the Sichuan salt brine pump suction to the ground. The book contains: the bamboo tube, no bottom orifices on the leather hanging a few inches out of the water, gas, breathing and the opening and closing of a cylinder caused by water bucket number. "Using the method of pump water to irrigate seedlings induced in the Ming Dynasty also talked about the" tree "in the book, the ancient China siphon principle is also discussed. During the northern and Southern Dynasties, the book "Yin Zi nine drugs", said: "the bottle stored two orifices, the water to the reality of the" pour "; closed a water, the lid (gas) does not rise, then (water) does not drop. A well is full of water, but it does not drop

Q: How do the rubber tubes fit into the galvanized pipe?: The inner diameter and outer diameter of the galvanized pipe must be determined.

Q: Is flexible rubber joint and telescopic device a kind of thing?: The utility model discloses a pipe expansion device, which is a connecting piece which is compensated by the size change caused by thermal expansion and cold contraction in the pipe connection. There are two kinds of pipe expander, one is rubber pipe telescopic device, and the other is metal pipe telescopic device.

Q: M40 and M50, and then the hose is 2 "what does the box connection mean?": M40 and M50 are the specifications of the teeth, but you do not specify the spacing of the teeth.

Q: What's the difference between a vulcanized rubber tube and an intake manifold?: Air intake pipe is the air from the air inlet, through the air filter, until the individual cylinder into the front of this section of the pipeline, is the main intake line of the engine, but also the total intake line.

Q: The rubber is sheathed on the metal cylinder. How can it be connected?: If you describe it, it is recommended that a soft binder such as 704 silicone gel will be used to prevent shock absorption and separation. Metal surface to rust treatment, clean can be coated adhesive, rubber cover surface is best polished, degreasing treatment effect is good!

Q: Laboratory condensate water pipe must use rubber tube, shall not use latex tube reasons: Low temperature bending test at low temperature: hose clamp on rigid torsion wheel diameter hose diameter 12 times, for 6 hours at a low temperature, twisted 180 degrees within 12s when the measured torque and the standard temperature measured torque ratio. Low temperature bending: hose clamped in the diameter of the hose within 12 times the torsion wheel, parked at low temperatures for 24 hours, in the 10s to reverse 180 degrees, check whether or not the internal and external plastic brittle fracture and damage.
