Q:How to detect the reliability of rubber hose

Low temperature bending test at low temperature: hose clamp on rigid torsion wheel diameter hose diameter 12 times, for 6 hours at a low temperature, twisted 180 degrees within 12s when the measured torque and the standard temperature measured torque ratio. Low temperature bending: hose clamped in the diameter of the hose within 12 times the torsion wheel, parked at low temperatures for 24 hours, in the 10s to reverse 180 degrees, check whether or not the internal and external plastic brittle fracture and damage. Test of low temperature brittleness measurement hose is the most simple specimen should be bent 90 degrees at low temperature, or a hose after freezing compressed 1/2 to see whether the embrittlement, another method is to use a certain weight of the heavy hammer falls freely, to see if the specimen embrittlement impact specimen.

Q:Is the electric water heater well connected with the metal hose?

The electric water heater, now in the industry are required to use PPR on the inlet and outlet pipe welding, a long service life, can effectively control the water heater outlet Water Leakage; on the other hand, can avoid the water heater power switch for two grounding and frequent take-off effectively. Therefore, the metal pipe connection does not meet the safety and installation specifications

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: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?

The integral type is a pressure hose, and the hose joint is mostly of two parts, and the integral part combines the two parts together

Q:What are the rubber pipe joints perfectly joined to the pipe fittings?

Rubber tube joints are flanged in general. Thread.

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

The tensile strength of adhesive joints that can resist the ultimate capacity rubber tensile failure, tensile test piece refers to fracture when the unit section of the load, also known as tensile strength, tensile strength, unit MPa (MPa). Tensile strength is generally used as the main physical and mechanical standard in rubber joint industry.

Q:How can the soft joint of the pipe be elongated during use?

Solution: the pipeline on the pipeline joint soft products need to increase to prevent stretch device (anti rato limiter), can limit the pipeline effectively soft joint work in the normal length, effectively ensure the service life and the effect of the product. Recommended products: KXT type reinforced pipe soft joint.

Q:What kind of material is the rubber tube with acid, alkali and high temperature resistance made of?

To acid, but also high temperature resistant material, only silica gel can do. Silica gel has a high temperature resistant material, can be used at 300 degrees high temperature for a long time, instant high temperature can reach 350 degrees. It's Jiao Jiao in the rubber hose.

Q:M40 and M50, and then the hose is 2 "what does the box connection mean?"

This should be called joints, hose connectors or joints or the traditional water tower.
