Q: What do you mean by "DN" on hydraulic hose?: DN stands for nominal diameter. The standard diameter after standardization, the midpoint between the inner diameter and the outer diameter, in units mm.

Q: Hydraulic hose joint dimensions: Metric plain thread1. metric screw thread with a capital M, tooth type angle 2 degrees =60 (alpha tooth type half angle);2. metric ordinary thread by pitch, coarse teeth, ordinary thread and fine teeth, two kinds of ordinary thread;2.1. coarse tooth ordinary thread mark generally does not indicate the pitch, such as M20 means coarse thread; fine tooth thread mark must indicate the pitch, such as M30 * 1.5 for fine tooth thread, in which pitch is 1.5.2.2. common thread is used for the connection and fastening between the mechanical parts, and the general thread connection is mainly made of coarse thread. The thread strength of the fine tooth thread is slightly higher than that of the same nominal diameter, and the self-locking performance is better.Mark 3. metric screw thread: M20-6H, M20 * 1.5LH-6g-40, where M represents a common thread metric, 20 nominal diameter thread is 20mm, 1.5 pitch, LH said, 6G 6H left, said thread precision grade, precision grade of internal thread uppercase, lowercase precision grade of said external thread, 40 screwing length.

Q: Plastic metal hose connector model specification, who knows?: Package type plastic hose is many, the most common is the DPJ thread joint, DPN joint, DKJ card connector, DGJ self fixed joints, Glenn joints, fittings

Q: What happened to the soft rubber flat?: A slightly heated or pressurized medium will return to its original condition.

Q: Can the natural gas hose not exceed 1.5 meters or 2 meters?: The gas hose on the principle of not more than 1.2 meters, and regularly check the technical requirements, 1-2 must be replaced if the temporary gas can also be longer, if long-term use, as far as possible the use of metal pipe joint and the gas stove can also use metal hose, high safety factor.

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: Hydraulic hose joint configuration: Gas safety hose joint: a joint security guarantee gas transmission, including metal hose, Baotou, connecting pipe and a connecting nut, one end of the connecting pipe and hose, metal hoop pressure Baotou into one, the other end is connected with the inner hole of flange nut for different aperture of two parts, large hole diameter is slightly larger than the connection the flange is provided with internal thread, big hole depth is larger than the thickness of flange, hole diameter is slightly larger than the connecting pipe outer diameter and smaller than the outside diameter of the flange.

Q: Toilet hose and water tank joints leaking, how to repair?: No rib sleeve, the use of pipe outside the buckle fixed, sealed, may be the aging of the tube, buckle clamping difficulties and other reasons. If the pipe is aging, you can cut or replace the tube in the aging part. It is difficult to buckle and clamp, so you need to change the buckle.

Q: Automotive applications of rubber hose: Each kind of rubber has its characteristic, therefore is specially important in the hose material selection. Basically the high-end cars use materials is relatively good, some poor materials using mini car, van, car and as some in the use of nitrile rubber as fuel tube, nitrile rubber are not suitable for fuel system. Thus, the substitution of epichlorohydrin rubber fluorine rubber hose is relatively extensive.

Q: Difference and application of rubber joint and rubber expansion joint: The utility model can be used to reduce the vibration and noise of pipelines, and can compensate for thermal expansion and cold contraction caused by temperature changes. Rubber expansion joints are used in chemical, construction, water supply and drainage systems!
