Stainless steel fittings and stainless steel fittings used in the marine industry

Date:2017-11-27 Author: Click:

In the hydraulic industry, stainless steel fittings are used in a wide range of vessels, and there are also many types of stainless steel fittings. In 4800 multi-purpose container vessels, which are technology-intensive vessels, they require high process quality and strict quality control. All stainless steel fittings , Stainless steel pipe fittings (including pipe, valve fittings, stainless steel fittings couplings) are supplied by Noble precision matching, hydraulic system stainless steel connector fittings with ferrule fittings, the entire hydraulic system in the sharing of hundreds of card fittings, specifications There are 5 types of stainless steel fittings and stainless steel fittings from 6 to 22. However, the quality of installation of the ferrule joint is the key to ensure the system's densification. To ensure the installation quality of the ferrule fitting, we first analyze the structural features and sealing principle of the ferrule fitting in the stainless steel fitting.

First, the card sets of stainless steel seal sealing principle

The basic structure of the ferrule stainless steel pipe fittings consists of three basic parts: a stainless steel connector body, a ferrule and a compression nut (FIG. 1). The ferrule is the key part.

The ferrule is a metal ring with a cutting edge on the inner end, which has good rigidity, hardness and toughness. Stainless steel adapter sleeve surface hardness is generally between 5 to 63, the hard layer depth of 05 and II, the substrate hardness between 9891 ~ 96. Stainless steel fitting ferrule During assembly, when the compression nut is tightened, the ferrule is propelled into the 24 "taper hole of the stainless steel fitting body under the action of axial force. The stainless steel fitting ferrule generates a radial force under the action of radial force Shrinkage, so that the inner sleeve cut into the pipe wall and the outer wall to form an annular groove, as shown in Figure 2, paragraph 0. The depth of the annular groove is about 3 ~ 0501111, forming a seal between the sleeve and the outer wall of the tube ; At the same time, the outer wall of the stirrup and stainless steel joint body 24. Tapered hole completely fit together to form a seal between the sleeve and the stainless steel connector body taper hole, as shown in Figure 2, paragraph 6. "6 Two sealing tapes seal the tube. Seen from the sealing principle of the ferrule-type stainless steel pipe fitting, it can be seen that the quality of the ferrule itself is good and the sealing tape is formed. "6 Whether the formation is good or not is a key issue that relates to the leakage of the stainless steel pipe fitting.
