Are stainless steel joints and water pipe joints good?

Jul 21,2022 / BY DEVELOPERS
I dare not talk about others, but this is definitely good, better than plastic pipe joints. Plastic pipe joints leak water, but they will not leak. Plastic pipe joints will age and burst easily, while stainless steel pipe joints will not burst, but also It has a shockproof effect, and the lifespan is incomparable. The lifespan of stainless steel water pipe joints is 70-years.

What are the specifications and models of stainless steel metal hose joints? How to choose?

With the development of society, there are more and more applications of stainless steel products in life, mainly because stainless steel has many advantages, and stainless steel is resistant to corrosion by weak alkaline media such as air, steam and water, so people like to use stainless steel for more many daily necessities. The stainless steel metal hose joints that I want to introduce to you today mainly introduce the street models of stainless steel metal hoses? There is also how to choose stainless steel hose joints, hoping to provide you with convenience in life.

Classification of stainless steel metal hoses:
NPT, PT, G are all pipe threads
NPT is the abbreviation of National (American) PipeThread, NPT is the American tapered pipe thread, used for sealing. It belongs to the American standard 60 taper pipe thread, which is used in North America. National standards can be found in GB/-PT is the abbreviation of PipeThread, which is a 55 seal taper pipe thread, which belongs to the Whitworth thread family and is mostly used in Europe and the Commonwealth of Nations. Commonly used in water And the gas pipe industry, the taper is 1:16. The national standard can be found in GB/-G is 55 non-threaded sealing pipe thread, which belongs to the Wyeth thread family. Marked as G stands for cylindrical thread. The national standard can be found in GB/-. G is the general name for pipe threads (Guan), and the division of 55 and 60 degrees is functional, commonly known as pipe circle. That is, the thread is machined from a cylindrical surface.

Metric threads are represented by pitch, and American and British threads are represented by the number of threads per inch, which is the biggest difference between them.

The metric thread is a 60-degree equilateral thread, the inch thread is an isosceles 55-degree thread, and the American thread is 60 degrees.

Metric threads are in metric units, and American and British threads are in imperial units.

Pipe threads are mainly used to connect pipes, and the inner and outer threads are closely matched, and there are two types of straight pipes and tapered pipes. Nominal diameter refers to the diameter of the connected pipe, obviously the thread diameter is larger than the nominal diameter.

Five elements for the selection of metal hoses:
(1) Dimensions
The nominal diameter of the hose, the joint type (mainly flange connection, threaded connection, quick joint connection), the size of the metal hose, and the length of the hose are selected.

(2) Pressure
According to the actual working pressure of the hose, check the nominal diameter and pressure gauge of the corrugated metal hose, and decide whether to use the stainless steel mesh type metal hose.

(3) Medium
The chemical properties of the medium conveyed in the hose determine the material of each part of the hose according to the corrosion resistance of the hose material.

(4) The working temperature and range of the medium in the temperature hose; the ambient temperature when the hose is working. When the temperature is high, the pressure after temperature correction must be determined according to the working pressure and temperature correction coefficient of the metal hose at high temperature, so as to determine the correct pressure level.

(5) Status
According to the state of the hose when it is in use, refer to the correct use and installation method of the stainless steel metal hose in Haizhizhou and the optimal length of the hose during settlement compensation. The length calculation of the various motion states of the hose and the smallest bend of the hose Factors such as the number of times and the minimum bending radius, and the parameters are correctly selected for the length of the hose and installed correctly.

The above is the introduction of the models of stainless steel metal hose joints and the selection of stainless steel inlet hoses. I hope it can help you to provide some help in your daily life. In fact, stainless steel metal hose joints have many advantages. Stainless steel metal hoses have flexible spacing, good scalability, no blocking and stiffness, light weight, good caliber consistency, softness, repeated bending, good flexibility and many other advantages. , so more and more people choose to use it.
