Who can get under the natural gas metal hose brand which is better

The stainless steel metal hose is composed of three parts: the inner corrugated hose, the weaving mesh sleeve, and the joint. The raw material is usually stainless steel L, 321

Differences and differences in the quality of stainless steel metal hoses For the layman, the differences and differences can only be made from the appearance, appearance: the quality of the weld, the softness of the hose, the finish. Nowadays, there are many hose manufacturers on the market, and most of them do not produce semi-finished products, and they are all attributed to assembled assemblies.

There are few units that can pass the real quality.

Due to the low cost, the metal hose in the static use environment is not the main medium for circulation, as long as the raw materials are qualified, it is usually able to be used, but it is necessary to pay attention to regular replacement. What really affects the quality of stainless steel hoses is the quality of the corrugated hose and the welding quality of the corrugated hose and fittings.

Due to the competition, many hose manufacturers are trying to save the cost of data, and the way to save is: 1. Hose corrugated data, weaving nets, and joint materials. 2. The semi-finished hose with a very dense wave distance is increased by stretching, so that the length of the semi-finished product is increased.

The above two ways to save information are extremely bad, because the user can not find out when the pressure test can be qualified and start to use, and the quality problem will be presented after a period of time.

Hebei Longzhong rubber products, the production of metal hoses.

Summary. Hello! We're glad to answer your questions!

Hello natural gas pipe hose is more suitable, its safety xing is higher than that of hard pipe, and it is more convenient to operate in terms of installation and maintenance. The hose used in natural gas is not ordinary, special pipes need to be used, including rubber, aluminum-plastic and other pipes, if it is connected with the indoor air source terminal, it is recommended to use stainless steel corrugated hose, which is more safe and secure, and is not prone to damage and leakage.

Hello! We're glad to answer your questions! Hello natural gas pipe hose is more suitable, its safety reputation is higher than that of hard pipe, and it is more convenient to operate in terms of installation and maintenance.

The hose used in natural gas is not the common stove, and it needs to be dressed up with a special pipe, including rubber, aluminum-plastic and other pipes, if it is connected to the indoor air source terminal, it is recommended to use stainless steel corrugated hose, which is more safe, and it is not easy to break and leak.

Aluminum-plastic pipe, also known as aluminum-plastic composite pipe, is a new type of pipe composed of intermediate longitudinal welded aluminum pipe, inner and outer layers of polyethylene plastic, and hot-melt adhesive co-extrusion between layers. When we make aluminum-plastic pipes into gas pipes, the pressure-bearing capacity of the pipes is relatively strong, and because the pipes can be extended for a long distance, there are fewer cases that require joints, so the gas is not easy to penetrate out and is relatively safe. However, we should avoid buying poor quality aluminum-plastic pipes, which are prone to deformation and breakage, which threatens the safety of our lives.

The aluminum-plastic pipes for gas are strictly controlled in the production process, and there are many advantages: strong ability to climb walls. The aluminum-plastic pipe for Rifeng gas has excellent carrying flexibility, and it is easy to climb the wall through the PVC casing to enter the households, and the installation is relatively simple.

Moreover, because the surface of the pipe is coated with a special PVC casing with a hidden layer, it can prevent outdoor ultraviolet damage and prevent problems such as climbing into the house, so it is recommended for consumers living in high-rise buildings to buy; The aluminum-plastic pipe for bending is easy to bend without reversing, the bending operation is simple, and the pipeline connection is convenient; Use shou life long. It has been proved by authoritative testing that the aluminum-plastic pipe for Rifeng gas can be used for 50 years under normal circumstances, and it can also provide warranty services to solve consumers' "worries".

Stainless steel corrugated pipes are better for indoor natural gas pipes.

If it is connected with the indoor air source terminal, it is recommended to use stainless steel corrugated hose, which is more safe and not easy to break.

The advantages of stainless steel corrugated hose are as follows:

1. Anti-aging.

Under natural conditions, rubber will undergo aging phenomena such as brittleness, hardening, cracking, and fracture, while stainless steel will not.

2. High temperature resistance.

The rubber hose is not resistant to high temperatures and is not flame retardant, and will soften and catch fire at high temperatures. The stainless steel body of the stainless steel corrugated hose is resistant to high temperatures, and the flame grilling only affects the PVC protective layer of the outer bread.

3. Anti-rodent biting.

The rubber hose is not resistant to rodent bites, but the teeth of ordinary animals can't resist the stainless steel body of the stainless steel corrugated hose.

Fourth, anti-falling off.

The rubber hose will not fall off naturally after installing the clip, but it cannot guarantee its safety in the case of aging shrinkage, external force pulling and other unexpected situations.

The stainless steel corrugated hose is generally connected by double guide threaded threads, which will not fall off without disassembly, and can withstand the pulling of an adult (75 kg), which can prevent the occurrence of accidental falling off.

5. Corrosion resistance.

The rubber hose is an organic material and is not resistant to oil, while the stainless steel corrugated hose is made of austenitic stainless steel, which can deal with common corrosive liquids, and the PVC protective layer also has a trace of anti-corrosion protection.

Sixth, long life.

The service life of the rubber hose is 18 months, that is, one and a half years, while the service life of the stainless steel corrugated hose is more than 10 years, and the comprehensive calculation cost is more economical and safe. <>
