Q:What's the rubber sleeve of the expander?

Expansion rubber flexible joint, installation of the flange sleeve telescopic device.

Q:Water heater hose 4 points and 6 points difference

The 1/ angle valve itself is provided with a switch and the long end is mounted to the wall pipe. If the toilet or faucet to repair, turn the corner valve closed, the hose will be out of water; 8 (7 points), the domestic pipeline and hose connecting the city 4 points thread; 4 (6 points) domestic are 6 points interface; imports of 4 points.

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:How can the rubber tube be used properly and how to use it properly?

The hose burst caused by frequent and severe pressure impact. This situation is not generally under the static pressure caused by too much, but the number and intensity and pressure impact. Engineering machinery in operation, will be repeated in the hydraulic tubing suddenly increased or decreased, which impact on the oil pressure of frequent the damage of the oil seal, resulting in increased, loosening hose leakage and rupture foaming and pipe joint. Therefore, in operation, the valve stem can not be too hard, must be gentle.

Q:What with the appropriate suction tube Dichotomanthes tube and rubber machine

The bellows are extruded by the extruder, and the winding tubes are wound in circles

Q:The rubber is sheathed on a metal cylinder. How should they be connected?

With the combination of metal rubber is coated with adhesive before production and rubber vulcanization shaping, you can use this temporary experiment 502 geliahao for glue or adhesive, but the disadvantages of this thing with winter is not strong, the metal surface must be clean

Q:The gas water heater uses metal pipes and rubber pipes

Metal pipes are good. Rubber tubes are easy to fall off

Q:Must the hose for the cooker be made of oil resistant rubber hoses?

Stove for rubber tube not only to the requirements of oil resistance, acid and alkali resistance, high temperature resistance, aging resistance and flame retardant have strict requirements, rubber gas pipe service life in 2 years or so, there will be over the period aging phenomenon.

Q:Acid burette and burette why different structure

The reason is that the glass is acid resistant, but it is caustic.

Q:How often do the oil - resistant rubber pipes undergo atmospheric pressure testing?

Bending test: after bending the hose to a certain extent, measure the minimum outside diameter of the bending part and the ratio of the outside diameter before bending, the passing capacity of the steel ball and the bending force when the tube is pressurized.
