Q:The newly purchased natural rubber tube is too large. How can it be removed?
The activated carbon is divided into 8 parts, put in the dish, the dumbbell rubber smell removed - prepare 400 grams of ash, used to be among them after washbasin packing box of formaldehyde, because some of the harmful substances is colorless and tasteless, more clean, more secure. In the bubble tea, put in the refrigerator can achieve the deodorization effect. If you do not have tea, you can also cut lemon or willow, and only half a small piece will be effective. Smoke in room. The soaked waste tea leaves dried, placed in the corner of the room, using the principle of physical adsorption of tea to remove dumbbells, rubber flavor. You can also use a towel dipped in diluted vinegar, go to the dumbbell rubber flavor.
Q:Hose connector JB1885-77 what is the standard?
The pipe joint oil sheet, wool, steel board, combined sealing washer or sealant leak, whatever the material, should first check the seal is damaged, and rough conditions such as deformation, aging, and then take corresponding measures.
Q:What is the function of the rubber pipe joint and the installation pipe?
The action of the rubber pipe joint on the installation of pipes:1. Small size, light weight, good elasticity, easy installation and maintenance.2. After installation, the transverse, axial and angular displacement of the pipe vibration can be absorbed. The pipe is not concentric and the flange is not parallel.3 、 after installation, it can reduce the noise caused by vibration of pipes, pumps and so on, and has strong vibration absorption ability.
Q:How should we distinguish between the silicone hose and the rubber tube?
Silicone hose is relatively soft, flexible, and looks better than other rubber tube gloss, color is mostly red, blue, translucent and other colors. Others, such as three yuan ethylene propylene and nitrile rubber hose, are basically black.
Q:How to determine the tensile strength of GB rubber joint?
The tensile strength of adhesive joints that can resist the ultimate capacity rubber tensile failure, tensile test piece refers to fracture when the unit section of the load, also known as tensile strength, tensile strength, unit MPa (MPa). Tensile strength is generally used as the main physical and mechanical standard in rubber joint industry.
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:Aging of natural gas pipeline
Replace gas hose.The gas hose is a special hose connection of gas pipelines and gas appliances, according to the analysis of some gas accident statistics, because the gas hose aging or bitten by rats caused by gas leakage accidents accounted for more than 30% of all gas accidents.
Q:Are the bridges, bellows and rubber tubes drawn out or are they drawn only? And the bellows are tensioned with the steel strand?
It is relatively rare, usually corrugated pipe for zinc metal corrugated pipe, the construction unit may be in order to prevent pipe blockage, when pouring concrete, the corrugated pipe with rubber tube, after pouring completed final setting, you can pull out rubber tube. Bellows need not be drawn.
Q:What is a rubber core pulling method?
When using the core pulling method, the hole is usually made of 5 - 7 layers of canvas and 6 - 7mm thick rubber tube. The hose can be used for retaining the straight lines, curves or broken lines.
Q:How much is a gas hose a metre? At least 1 meters, 5 safe?
1, liquefied petroleum gas will soften the ordinary rubber tube, please use special rubber tube.2, often check and clean hose, found aging, cracking, burn, rat worm bite marks, should be replaced immediately. It is recommended that the hose be replaced in two years under normal conditions.3, gas hose length of not more than 2 meters, after passing the place is not allowed to have electrical appliances.4, hose do not close to the stove surface, so as not to be flame barbecue.5, the hose does not cross the wall, doors and windows.6, do not press or fold the hose, so as not to plug, affecting the continuous gas supply.At the interface, and appliance, 7 hose valve, please use the pipe truss, to prevent the shedding of leakage.
