Q: Is hot melt hose toxic and harmful?: Hot melt pipe using imported Teflon liner, has good flexibility, anti adhesion and resistance to high temperature (up to 250 degrees), can greatly reduce the carbonization phenomenon;

Q: What are the production processes and characteristics of high pressure rubber hose?: Production flow chart of high pressure steel wire braided hose:High voltage wire winding production process: rubber hose, pipe extrusion, boiled casing (core wipe silicone oil), wrapped around the screen (screen on the casing after finishing cutting winding), a layer of glue, the first layer of steel wire winding, two winding layer of glue, second layers of wire, third in the layer of glue, third layers of wire winding layer, fourth layer, fourth layer winding wire, package cover, water roll of cloth, cloth, water solution of vulcanization, mandrel stripping, a hydraulic, appearance and dimension inspection and packaging storage.

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: 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: What is the rubber sleeve flange connection sleeve?: Rubber flexible joint flange connection sleeve flange gate valve quota.

Q: HDPE double wall corrugated pipe joint shall be made of elastic sealing rubber ring and socket joint interface. What are the requirements for rubber ring joint?: The interface method should be carried out according to the following procedures: DN400 pipeline and below, by a man with a cotton rope hook is installed pipe socket, the other one with a long lever oblique insertion based cross baffle against the tube end of the center position, and then forced the tube slowly into after the installation of HDPE double wall corrugated pipe the pipe socket to a predetermined position; more than two sets of DN400 pipeline by hand hoist will pull in pipe section. When the interface is closed, the spanner on both sides of the pipe section shall be pulled synchronously, so that the rubber sealing ring is properly positioned and is not distorted or not falling off.

Q: Why should the water stop strip be joined by heat instead of superposition?: Thermal connection is the safest and most reliable method of joint treatment, but it has certain requirements for technology.

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: How often do the oil - resistant rubber pipes undergo atmospheric pressure testing?: Suction flat test: in the 1min vacuum, after maintaining 10min, with diameter of 0.9 times the diameter of the hose rolled over, check the degree of collapse of the hose. Some standards used to measure the rate of change in the outer diameter of the hose to indicate the extent of deformation of the hose.

Q: What material is used in the gas pipeline to reduce the wastage?: Galvanized pipe is a pipe in galvanized steel pipe surface, a hot galvanized and galvanized pipe, galvanized pipe while the production cost is low, but easy to corrosion, therefore, is usually used for conveying gas hot galvanized pipe. The galvanized pipe not only has higher corrosion resistance, but also has a long service life, but because of its excessive interface, construction trouble is gradually being eliminated by the market.
