5、2 Superseding 2551 MAY2010 Recommended Practices for Fluid Conductor Carbon, Alloy and High Strength Low Alloy Steel Tubing Applications - Part 3: Procurement RATIONALE The user community has expressed a need for additional documented knowledge associated with the design, expected performance and pr
6、ocurement of metallic fluid conductors. This revision to SAE J2551 reorganizes the document into three parts, design and fabrication, general specifications and performance requirements and procurement. The following changes and additional information is intended to bring this document up to date wi
7、th current industry technology and provide comprehensive application and procurement information requested by the user community. In addition, the document title has been revised to include steel tube materials that have been recently added as SAE standards. FOREWORD The May2010 edition of SAE J2551
8、 was published as a single document covering the design and fabrication of carbon, alloy and high strength low allow tube assemblies. SAE J2551 has been organized into three sections as follows: 1. SAE J2551-1 - Recommended Practices for Fluid Conductor Carbon, Alloy and High Strength Low Alloy Stee
9、l Tubing Applications-Part 1: Design and Fabrication 2. SAE J2551-2 - Recommended Practices for Fluid Conductor Carbon, Alloy and High Strength Low Alloy Steel Tubing Applications-Part 2: General Specifications and Performance Requirements 3. SAE J2551-3 - Recommended Practices for Fluid Conductor C
10、arbon, Alloy and High Strength Low Alloy Steel Tubing Applications-Part 3: Procurement This SAE Recommended Practice is intended as a guide to consider when procuring carbon, alloy and high strength low alloy steel tube assemblies for fluid power and general applications. It is subject to change to
11、keep pace with experience and technical advances. Experienced designers and users skilled in achieving proper results, as well as the less experienced, may use this outline as a list of recommendations to consider during the procurement process. Fluid power systems are complex and require extensive
12、knowledge of both the system requirements and the various types of tube. Therefore, all-inclusive, detailed, step-by-step instructions are not practical and are beyond the scope of this document. Less experienced designers and users who need more information may consult specialists such as experienc
13、ed tube designers and fabricators. This guide may improve the communication process. SAE JJ2551-3 Issued FEB2013 Page 2 of 15 Following this document is highly recommended by the participating SAE/ISO organizations and their members. Adherence to these guidelines may assure the users they will creat
14、e tube assemblies that can be efficiently manufactured, conveniently packaged/shipped, proficiently installed on their equipment, will perform adequately and safer to established industry standards and they will be using common practices and components that may be easily serviced anywhere globally.
15、Safety Considerations - These documents include considerations to facilitate safer conditions when these products are in use; note these carefully during all phases of design and use of the tube assemblies. Improper selection, fabrication, installation, or maintenance of tube assemblies for fluid-po
16、wer systems may result in serious personal injury or property damage. Adherence to these recommended practices could reduce the likelihood of component or system failure, thereby reducing the risk of injury or damage. The application of hydraulic tubing with fluids under pressure exposes users to ri
17、sk due to mechanical or injection hazards and the environment to contamination from leakage. Users are reminded to consider the proper selection of components, fabrication of tubes, installation and maintenance procedures to address this potential risk. TABLE OF CONTENTS 1.

20、 15 1. SCOPE 1.1 Purpose SAE J2551-3 recommended practice provides recommendations for a procurement process for carbon, alloy and high strength low alloy steel tube assemblies for fluid power applications utilizing commonly available manufacturing methods and general guidelines for tube selection a
21、nd application. 1.2 Field of Application These recommended practices are intended for general application and hydraulic systems on industrial equipment and commercial products. Aircraft and Aerospace applications were not considered during the preparation of this document. Since many factors influen
22、ce the pressure at which a hydraulic system does or does not perform satisfactorily, these recommended practices should not be construed as guaranteed minimums. For any application, it is recommended that sufficient testing be conducted and reviewed by both the user and supplier to ensure that requi
23、red performance levels are met. For use of these recommended practices and connectors in conditions outside the pressure and temperature of limits specified, the fabricator must be consulted. Both metric and inch tubing should be considered to accommodate hydraulic system design requirements. In the
24、 past, these requirements have been met predominantly with inch tubing; for new designs, metric tubing should be considered. 2.
