Q:What about leakage of hose joint?
Sleeve joint event Water Leakage, you may need to remove the connector and reinstall the many water pipes, it should be timely reporting the repairman to repair.
Q:Can the spring hose joint be connected to the tap?
1 use dry cloth or paper towels to wipe the elbows of the pipe, and also to dry on the bottom;2, more than 10 minutes, in the use of dry towel on the elbow section, pay attention to observe, if the paper towel is wet, the exemption proved that the site leaks. If there is no problem with the elbow, use the same method to test the lower part of the elbow and locate the leaking part.
Q:Pipe rubber shock absorber: flexible joints and flexible connections are not the same thing
The soft connection is mainly composed of flexible body (bellows), net body and various forms of joint, compensating the deformation of the axial, transverse and angular directions of the absorption pipeline, and eliminating the stress.
Q:The difference between silicone tube and rubber tube
Silicone tube 100% non-toxic, tasteless, fine silk, silicone silicone tube (article), high pressure resistant silicone tube, silicone tube, gear shaped sealing strip, shaped article, food grade (non-toxic) silicone tube (article), medical silicone tube, silicone tube, silicone tube medicinal woven (used for conveying working pressure, liquid food, pharmaceutical and biological products. ) medical silicone pipe joint, silica gel sealing tube, flame retardant tube (strip), silica gel foamed pipe (strip), high temperature resistant silicon rubber tube, performance: cold resistance, high temperature resistance. Harmless non-toxic and tasteless; suitable for small household appliances (coffee pot, kettle, electric iron, electric cooker, frying pan, disinfection cabinet, drinking machine, pulp machine, bread machine, gas cooker, water heater) and electronic, automobile, medical and other mechanical products.
Q:Flexible rubber joints. What do they mean by flexing?
In this respect, there are two kinds of materials (or structures): 1) stainless steel, a section of corrugated pipe; 2) made of rubber, that is, when a section of rubber cylinder. There are 2 kinds of parameters, such as diameter, pressure and linking method.
Q:What's the metal hose for fire fighting?
1 the metal hose is made of 1Cr18Ni9Ti stainless steel, and has strong corrosion resistance.The 2. hose tube is made of thin wall stainless steel tube. It has strong flexibility, flexibility, strong bending and vibration resistance, and reinforced protection of woven mesh sleeve, so that it has higher bearing capacity.The connection of the ends of the 3. flexible pipes can be made into other connecting ways except the thread and the flange standard, so that the connection and the use are convenient.4. the product is not only suitable for mating with rotating joint, but also widely used in soft connection of many kinds of fluid medium transportation.
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:What do you mean by "DN" on hydraulic hose?
DN stands for nominal diameter. The standard diameter after standardization, the midpoint between the inner diameter and the outer diameter, in units mm.
Q:Can the natural gas hose not exceed 1.5 meters or 2 meters?
If the gas is longer, to Caution! Protective tube wall, as far as possible, to prevent accidental damage risk of gas pipe.
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.
