Q:Difference between non-standard rubber joint and national standard rubber joint

Rubber joint national Ministry of water conservancy is standard CJ/T208-2005 documents of rubber joint standard, this paper has clear rules for the product, identify the products should meet the following characteristics: standard rubber joint extrusion is produced by the rotation of the screw, the glue is advancing, and with the help of the mouth, but the needs of various semi-finished extrusion the shape of the. The extrusion process is characterized by uniform and compact quality and easy conversion of semi-finished product specifications and section shapes. The extrusion process of the national standard rubber joint in the extruder is divided into two parts: one is the extrusion system used for pushing the rubber; the two is the die system, which is used to form the rubber to make a definite section shape. Therefore, in the process of pressing, the rubber layer is usually more than ten layers, and the rubber joint has the characteristics of compact structure and high pressure resistance.Non-standard rubber joint is in the national standard between substandard products and national standard products, often illegal businesses use to reduce the rubber joint, the number of layers to reduce the cost of rubber joints. Use non-standard products instead of GB products. Non-standard products in use process, because the arc bearing layer, rubber layer is insufficient, the strength drops, in the use process is easy because the pressure withstanding insufficient causes the pipe network to burst.

Q:How to install the water hose and do you use the tape? Or direct installation?

The pipeline key fixed: if it is not fixed, at the disengaged joint under the action of water pressure, or joint fixed point is the best, because only the most effective joint will be fixed, hard tube and building reliable fixed connection, can guarantee the normal use of the time to extend the hose.

Q:How can I remove all the flavor on the rubber hose?

Buy Rubber deodorant. Or dry, there is no other way.

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:The rubber is sheathed on the metal cylinder. How can it be connected?

If you describe it, it is recommended that a soft binder such as 704 silicone gel will be used to prevent shock absorption and separation. Metal surface to rust treatment, clean can be coated adhesive, rubber cover surface is best polished, degreasing treatment effect is good!

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

Hose selection and installation caused by improper hose rupture. When replacing the hose, the hose wire length, number, shape and size of the joint should be reasonable, and should try to reduce the degree of bending in the hose; tighten union nut, do not make the hose distorted, excessive bending and twisting will reduce the service life of the hose greatly; some easily friction parts should take protective measures to prevent the hose due to wear and burst.

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:Excuse me: how can a pen with a rubber tube attract more ink?

If this can not be solved, you can suck a part of the pen out, inverted (NIB upward), gently knock, so that ink into the hose, and then continue to suck ink, repeatedly, so that the pen "drink" full".

Q:Between the two flanges in the middle of the rubber tube, what is the name of the connection?

The product is mainly composed of inner and outer rubber layer, cord fabric and steel wire ring. It is formed by vulcanizing with metal flange at high temperature and high pressure

Q:Can the high-pressure rubber hose be followed by water pipes? Will it be poisonous?

High pressure rubber tube adhesive for synthetic rubber, is generally not recommended for civil water, if it is regular water
