Introduction

In a hydraulic transmission system, power is transmitted and controlled through pressurized fluid in a closed circuit. The hydraulic component is connected to the conduit (hard pipe or hose) through its oil port with a pipe joint. The hard pipe is a rigid conduit and the hose is a flexible conduit. This document is based on the type, shape, part type, stud end seal type, working pressure level, joint material, sealing material materials and other differentiated characteristics, standardize the naming of pipe joints to promote the use of threaded pipe joints, plug-in pipe joints, flange pipe joints, soft Standardized naming for products such as pipe fittings, screw plugs, and quick couplings. Hydraulic transmission connection identification and naming

1 Scope

This document provides the classification and naming methods for pipe joints and similar products, and establishes a unified product naming structure. This document applies to the identification and naming of hydraulic pipe joints.

2 Normative reference documents

This document has no normative references.

3 Terms and definitions

There are no terms or definitions to be defined in this document.

4 Naming and format

4.1 General When purchasing pipe joint parts described in the national standards formulated by SAC/TC3/SC5, the naming and code format is shown in Figure 1. When a threaded pipe coupling has multiple end types, the stud end should be identified first (if applicable, e.g. SDSWS. Rotary Stud End Straight Pipe Coupling head). If there is no stud end, the naming sequence should be specified according to the description of the part (for example, WDRDNP is used for a welded reducing pipe). If the takeover end If it is an external thread, it does not need to be reflected in the pipe joint type code. Indexing serial number description. 1---Pipe joint name. the name of the parts in the standard (such as. pipe joints, hose joints, quick-change joints, etc.); 2---Pipe joint standard number. international standard code or national standard code; 3---Pipe joint type naming. The abbreviation name consists of the pipe joint connection end type code (see Table 1), the rear nozzle joint shape code (see Table 2), the rear nozzle joint zero Part type code (see Table 3), etc.; 4---Pipe joint size (see 4.2); 5---Pipe joint material code (see Table 7), followed by sealing material code (see Table 8).
