Q: Access toilet water inlet hose joints, how to repair water?: However, be careful not to hold back too much to prevent the toilet from being cracked. Because before if overwind, or rust, is not open, can only remove the drainage valve inside with a pipe wrench stuck open.

Q: Can black soft rubber pipes be used as water pipes? Why is there a pungent odor?: If you have a strong smell, it must be made of reclaimed gum, and it's inferior reclaimed gum. You smell the smell of reclaimed tar.

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: What is the maximum pressure that a hose can bear?: The working pressure of general industrial hydraulic high pressure hose is about 35MP, and the bursting pressure can reach 60mp. It doesn't make any sense because there is no higher hydraulic pump that can work above 35MP.

Q: Is flexible rubber joint and telescopic device a kind of thing?: The main features of metal pipe telescopic device are telescopic, large compensation and high temperatureUnder great pressure.And flexible rubber joint is a product!

Q: Hose connector JB1885-77 what is the standard?: The reason of high pressure hose joint leakage are the following: "a" ring aging or deformation caused by leakage; the "C" ring assembly is not in place, the two plane connection or "C" uneven pressure ring is cut caused by leakage; "a" ring without compaction, the elastic deformation caused by leakage; the "C" ring spigot groove deep caused leakage. In this regard, the need to re select the same diameter and thick section "C" ring, can also be provided with a sealing plane rabbet groove of cutting or grinding, in order to reduce the rabbet groove depth, the "C" ring has enough elastic deformation (compression should be between 0.35-0.65mm).

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: How can the hose of natural gas be connected to the water heater?: It should be noted that when the nut is installed, pay attention to each nut must have plastic or rubber soft gasket, gasket must be flat, it plays the sealing role of the joint of the pipe joint.

Q: Laboratory condensate water pipe must use rubber tube, shall not use latex tube reasons: Hydraulic test verification pressure test: Test hose and assembly under verification pressure, continue 30s-60s, whether to produce leakage, deformation and damage. Compression deformation test: keep 1 minutes under the specified pressure (work pressure, verification pressure or other pressure below the proof pressure), measure the length and diameter of the hose, twist angle and bend. Bursting pressure test: Determination of the pressure at which the hose burst during the specified step-up rate.

Q: Difference and application of rubber joint and rubber expansion joint: Rubber expansion joint is also called rubber joint, flexible rubber joints, rubber soft connection, soft joints, rubber expansion joint is formed by high temperature plastic rubber, rubber expansion joint and makes full use of the characteristics of rubber elasticity, high resistance, medium resistance etc..
