Q:Three yuan ethylene propylene rubber joint (high temperature resistant rubber joint) can withstand high temperature

Because three yuan ethylene propylene rubber does not bear oil, the mechanical strength is low, the price is expensive, therefore it is not suitable to make the oil resistant sealing product.

Q:Method for connecting glass tube and rubber tube

Put the glass tube wet with water, and then put the rubber tube water preheating, now holding a glass tube, a hand wring rubber tube, you can complete the glass tube and a rubber tube connection.

Q:What kinds of pipe joints can be divided into? What are the differences between the so-called one - piece pipe joint and other types of pipe joint?

Card sleeve type, welding type, flaring type, attached thread pipe joint, cone seal, flexibility, hand clamp, fast change, etc., the first three kinds are more used.

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

Due to the aging hose burst of high temperature oil. Operation engineering machinery, hydraulic system for power loss and oil heating, and the influence of the outside temperature (especially in summer), the sharp increase in oil. The oil using high temperature, banana aging, elastic variation, decline the strength and sealing performance, the hose will soon burst. Therefore, during the operation, when the hydraulic system temperature is too high, too fast, should identify the reasons, be excluded; summer homework, especially in continuous operation, should take necessary measures to cool down.

Q:What are the types of cable metal hose connections?

The utility model is mainly used for connecting the metal hose and the steel pipe, and the installation of the clamping sleeve is not required to be sheathed on the steel pipe

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:What material is used in the gas pipeline to reduce the wastage?

The rubber tube industry in our country has been developed for 50 years, and its application is very extensive. As with other gas pipes, rubber tube has the properties of corrosion resistance, high temperature resistance, but its service life compared to other types of pipeline is much shorter, so in our country, the rubber tube has been rarely used in gas transportation in the.

Q:How long is the service life of the gas hose?

The service life of the hose is two years. It is recommended to change it once a year,

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:Natural gas can be connected to a gas cooker. Can rubber tube be used?

Yes, rubber hoses are required for selection of rubber hoses.
