Q:What is the difference between the precast beam of the bridge and the method of pulling out the rubber tube after pouring the concrete? What's the difference between design and calculation?

Corrugated pipe is included in the design of the amount of engineering, the role is: reserved strand space. Its length is calculated when the work length of the steel strand.

Q:What kind of material is medical rubber tube?

Silicone rubber, of course, is environmentally friendly, non-toxic, harmless, such as high-pressure sealing ring in the pot. First of all, to the human body non-toxic first.

Q:Why are the lengths of the household combustion equipment linked to the gas pipe hose no more than 2 meters?

A pipe is a weak link. Many accidents occur on pipes. In theory, the leakage of pipe per unit length may be the same. Then, the longer the pipe, the higher the risk coefficient.In reality, the longer the tube, the higher the possibility of being clipped. For example, bending, stretching, foot work, cracking, aging, these are potentially dangerous.

Q:Is there a tolerance standard for rubber tubes in length?

Just think, in the use of the tube, is the important dimension of diameter and wall thickness of the pipe, a little a little long, short should not affect the use, especially the rubber tube, right?! so imagine, rubber tube should not have standard tolerances in length (requirements).

Q:Automotive applications of rubber hose

EPDM three yuan ethylene propylene rubber is used in automobile water pipe series. Such as radiators, hoses, air conditioning pipes, etc.. There are some higher performance materials, such as AEM, acrylate, high temperature and so on.

Q:Flex rubber joint installation skills, what are the materials of rubber soft joint?

Specification for installation of flexible rubber joints:Flexible rubber joints, piping construction, it is necessary to make it in a natural situation, not artificial products in the equipment, artificial deformation of the goods. When the pipeline medium for acid, oil, high temperature and other special information, should be higher than the pipe pressure, a gear of the joint.

Q:Method for inserting glass tube into rubber tube when assembling instrument

The sleeve method of different outer diameter glass tube should be determined according to the size of the outer diameter. If the outer diameter of the two tubes is not big, then the rubber tube with the same inner diameter can be connected. When connecting to the rubber sleeve in the larger outer diameter glass tube, the specific method, with a diameter from one end of the rubber tube of the same stick (such as chopsticks) inserted into the connection end to the rubber tube, rubber tube set in reverse, then the larger outer diameter glass tube against the wooden stick. The rubber hose forward turning sleeve on a glass tube, stick out.

Q:How to determine the tensile strength of GB rubber joint?

The tensile strength test specimen is dumbbell shaped and can be divided into 1, 2, 3 and 4 types, of which type 1 is universal, and the specific dimensions of each part of the sample are as follows:For non-standard specimens, that is, the maximum thickness of the narrow part of the sample taken from the finished product is specified as: type 1 is 3.Omm, type 2 and type 3 are 2.5mm, and type 4 is 2.Omm.

Q:What kind of material does hose screw protection cover have? What are their advantages and disadvantages?

The utility model relates to a pipe protecting sleeve, which is a new product replacing the traditional metal protecting spring used for the protection of traditional rubber hoses. Alias: hose sheath, rubber tube outside protection special nylon spiral sheath, etc..

Q:How about rubber transfusion hose?

In accordance with the mixer developed within the layer, the middle layer and the outer winding hose layer; while using extrusion equipment will soft core inner tubing extrusion and coated release agent in coating or hard core, but should pay attention to the use of liquid nitrogen freezing method can not die.
