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 of the tubes are 1 1/4 inches, and the K type mine connections are also 1 1/4, but there are two methods of KJR32 and KJR31.5D. But KJR31.5D, D means that the inner diameter is 1 1/4 inches.

Q: There are several ways to connect the built-in rubber stop: Is the cold adhesive rubber zhishuidai special cold glue, overlapped by the waterstop joints with grinder grinding section to 5~10 cm, glue can be compacted, has high strength, fast solidification has the advantages of convenient, time-saving, can meet the general engineering quality requirements.

Q: Can the natural gas hose not exceed 1.5 meters or 2 meters?: If the gas is longer, to Caution! Protective tube wall, as far as possible, to prevent accidental damage risk of gas pipe.

Q: Standard for implementation of type KXT-1 rubber joints: It is divided into 3 kinds: flange type, fixed flange type and thread type by connection. The structure can be divided into 5 kinds: single sphere, double sphere, different diameter body, bent sphere and wind pressure coil. A tubular rubber component is composed of inner and outer layers of rubber, cord and steel ring, which is vulcanized and molded and then combined with a metal flange or a parallel joint.

Q: How do you remove the burrs on the rubber joint quickly?: Frozen deburring machine is a kind of ultra low temperature using liquid nitrogen to make rubber, plastic products, zinc alloy burr occurs rapidly embrittlement, and under this condition, the burr of high-speed jet impinging particles of frozen products, so as to achieve both high quality and high efficiency removal products of burr, and keep possession the product itself does not change. The utility model can greatly improve the deburring precision of products, and has a high degree of intensification.

Q: Acid burette and how to distinguish the basic buret: The following is a rubber tube acid basic titration burette is below the piston

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: Flex rubber joint installation skills, what are the materials of rubber soft joint?: Flexible rubber joint is normal for medium temperature of 0-60 DEG C usually water medium such as oil, acid, high temperature and other corrosive and texture should be selected under the peace situation should be relatively Tenai data can not be blindly on rubber joint or universal.

Q: Laboratory condensate water pipe must use rubber tube, shall not use latex tube reasons: 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 kind of material does hose screw protection cover have? What are their advantages and disadvantages?: Hose cover is usually made of nylon or polyethylene
