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

GB and non standard. GB type rubber joint refers to the material selection and production in accordance with the relevant 02S404 or 02S312 standards of the Ministry of construction, and has strict requirements on flange thickness, flange thickness, diameter and thickness.

Q:How long is the service life of a rubber tube?

This is really bad to determine, the environmental impact is very large, so it is difficult to judge

Q:Can the rubber hose for the LPG cooker and gas cooker be general?

The characteristics of the rubber tube has physiological inertia, UV resistance, ozone resistance, resistance to high temperature (-80 to 300), high transparency, strong resilience, resistant to compression permanent deformation, oil resistance, impact resistance, acid and alkali resistance, wear resistance, flame resistance, voltage, conductive properties.

Q:What are the types of metal hose couplings?

DGJ jointStructure and characteristics:DGJ self fixing metal hose joint, it can connect non threaded steel pipe or screw free equipment outlet and hose, and save the thread setting process;The metal joint is made of zinc alloy. The surface is zinc plated, sanded or chrome plated. The structure is compact and the strength is high. The steel pipe and the metal hose are connected reliably, and the appearance is beautiful;The metal joint is self - fixing and is used to connect the metal hose to the non - threaded steel pipe or the screw - free equipment outlet;Suitable metal hose: JS, JSH, JSB, JSHG;Adaptation: steel thin steel wire pipe, black, tin pipe (water, gas);When choosing the DGJ self fixing metal hose joint, please pay attention to the specification and size of the connecting pipe hose.

Q:Is rubber tube harmful to drinking water?

There are drinking water standard rubber tube, ordinary hose can not be directly applied to drinking water, there is low toxicity!

Q:What is the essential difference between rubber expansion joint and rubber joint?

The expansion joint is also called expansion device, expansion joint and compensator. It is divided into several types, such as ripple compensator, sleeve compensator, rotary compensator and square natural compensator, and also has intubation type expansion joint. Among them, the corrugated compensator is more commonly used, mainly to ensure the safe operation of the pipeline, and has the following functions: 1.. Compensating the axial, transverse and angular thermal deformation of the absorption pipeline. 2. vibration absorption equipment to reduce the impact of equipment vibration on the pipeline. The deformation of the pipeline 3., absorption of seismic subsidence.

Q:What are the gas hoses?

The stainless steel is expensive, 40 yuan set.The rubber is cheap, 10 yuan a set.Where do you come from? I don't know. In our Shanghai gas, this price includes the labor cost of the installation to you. In other words, fix it directly for you.

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:How do the automobile rubber hoses combine with the quick couplings?

Turn the rotary handle on the quick connector to the open position first;

Q:How do you remove the burrs on the rubber joint quickly?

The thickness of the rubber joint burr than the thickness of the product is much thinner, so brittle speed than the speed burr brittle products quickly, in burr brittle and brittle products without this period of time can be hit by projectile projectile with frozen products deburring machine, thereby removing burrs in embrittlement.
