The stainless steel ferrule joint has the characteristics of strong connectivity, high pressure resistance, good sealing and repeatability, convenient installation and maintenance, safe and reliable work, etc. It is widely used in oil refining, chemical industry, petroleum, natural gas, food, pharmacy, instrumentation and other fields. Next, let's take a look at the introduction of stainless steel ferrule connector types.

(1) Stainless steel ferrule connector - DIN2353 single ferrule connector overview

The sleeve type pipe joint is composed of a joint body, a sleeve type pipe joint and a nut. When the sleeve type and nut sleeve are inserted into the connector on the steel pipe, after the nut is tightened, the outer end of the sleeve type is attached to the conical surface of the connector, and the inner edge is evenly bit into the seamless steel pipe to form an effective seal.

(2) Stainless steel ferrule connector - advantages of single ferrule connector

The single ferrule joint is characterized by strong connectivity, high pressure resistance, good temperature resistance, good sealing and repeatability, convenient installation and maintenance, safe and reliable work, etc.

(3) Stainless steel ferrule connector - DIN2353 single ferrule connector

The working principle of the single sleeve joint is to insert the steel pipe into the sleeve type, lock it with the sleeve nut, hold the sleeve type, cut into the pipe and seal it. Welding is not required when connecting with steel pipes, which is conducive to fire prevention, explosion prevention and high-altitude operation, and can eliminate defects caused by careless welding. Therefore, it is the perfect connector in the pipeline of automatic control devices for oil refining, chemical industry, petroleum, natural gas, food, pharmacy, instruments and meters and other systems. It is suitable for pipeline connection of oil, natural gas, water and other media.

(4) Stainless steel ferrule connector - double edge single ferrule connector structure

Two cutting edges, one cutting edge (1) and one stop edge (2), are used for the double edge single set joint. The stop edge not only forms the second seal, but also prevents the cutting edge from biting the pipe, thus improving the anti vibration and tensile capacity of the joint.

Jacket seals are mostly metal to metal seals. In order to improve the sealing performance and repeated installation of single jacketed joints, there are jacketed seals with elastic sealing rings. The elastic seal replaces the traditional hard seal of single ferrule joint, which has better sealing effect and better assembly.

(5) Stainless steel ferrule connector - introducing single ferrule connector

Single ferrule parts are divided into two systems. The first type, also called 24 degree compression pipe fittings, is commonly used in hydraulic pipeline systems. Design and manufacturing standards include DIN2353/ISO8344-1, JISB2351 and SAEJ514. The other type is usually provided by instrument pipe fittings manufacturers, and there is no unified manufacturing standard at present, such as CPI pipe fittings. Common stainless steel single socket joints include single blade single socket joint and double blade single socket joint.

(6) Stainless steel ferrule joint - single side single ferrule joint structure

Operating principle of single blade and single ferrule joint: the pipe is inserted into the bottom and the ferrule nut is pressed under the eaves. On the left side is the gap between the tapered hole squeezed into the connector body and the pipe, and the cone of the outer cone of the ferrule is contacted for sealing. The ferrule is embedded into the edge of the outer wall of the steel pipe, and the ring groove of the pipe pressure of the wall is sealed with a circular projection form; Further tighten the nut to make the middle of the sleeve slightly bulge, resulting in elastic deformation. The elastic stress makes the right end of the sleeve cone friction with the nut. To prevent the nut from loosening, the elastic deformation part can absorb the vibration in the hydraulic pipeline. In addition, the end of the sleeve can tightly hold the steel pipe, forming a conflict seal.
