Inspection and testing of valves
Chapter 1 Overview 1.1 Scope 1.1.1 This standard includes the requirements for inspection, inspection, supplementary inspection and pressure testing of gate valves, globe valves, plug valves, ball valves, check valves and butterfly valves. The above types of valves are elastomeric, non-metallic (eg, ceramic) or metal-to-metal. Flexible seal means; a. Soft seal, solid or semi-solid greases (eg oil seal, stopcock), b. Soft seal and metal seal combination, c. Design any other type of valve that meets the elastic seal leakage rates specified in Table 5. The AP1598 is a supplement to the API standard that references it, but the purchaser and the valve manufacturer agree that the AP1598 can also be used with other types of valves. 1.1.2 The inspection requirements apply to inspections and tests carried out by the valve manufacturer and any additional tests the buyer requires in the valve factory. The test requirements apply to the required and optional pressure tests performed at the valve manufacturer. 1,1.3 The provisions of this standard tests and tests are as follows: a shell test; b. On the seal test, c. Low pressure seal test; d high pressure seal test: c. Casting the appearance of inspection, f. High pressure gas shell test. 1.2 Reference Standard 1.2.1 This standard reference the latest version of the following standards, regulations and norms. ASME BL20.1 Universal Pipe Threads B16.11 Socket Welded and Threaded Forged Steel Pipe Fittings B16.34 Flanges, Threads and Weld Mating Valves MSS SP - 55 Valves, Flanges, Fittings and Other Piping Attachments for Castings Steel quality standards ---- visual method SP - 91 manual valve operation rules 1.2.2 This standard is to supplement the following APl valve standards.

During the execution of the purchase contract, the Buyer Inspector may enter any part of the manufacturing plant related to valve manufacture at any time. 2.2 Inspection outside the valve manufacturer When the purchaser specifies that the inspection includes shell parts manufactured outside the valve manufacturer, the parts should be subject to inspection by the buyer at the place of manufacture. 2.3 Inspection Notification When the inspection by the buyer is required, the valve manufacturer shall notify the buyer at the address listed in the order within 5 working days prior to the required valve test and required supplementary inspection or inspection. If the factory inspection is needed, the valve manufacturer shall also notify the buyer at 5 days in advance when and where it can inspect the shell parts manufactured outside the valve factory. 2.4 Scope of inspection Scope of inspection can be specified in the order, unless otherwise indicated, the inspection should be limited to the following. a, in the assembly process to check the valve to ensure compliance with the provisions of the order. Inspection may include the use of prescribed non-destructive testing methods. b. Witness the required and prescribed pressure tests and inspections on site. C Field witness any additional testing (see Section 2.6). d. Review processing records and NDT records (including specified ray inspection records). 2.5 Inspection 2.51 The valve manufacturer shall perform a visual inspection of all castings of valve bodies, bonnets and seals to ensure compliance with valve MSSSP-55. 2.5.2 The valve manufacturer shall inspect each valve to ensure compliance with this International Standard and the referenced procurement specifications (eg AP1600, see section 1.2.2). 2.5.3 All inspections shall be carried out in accordance with written procedures prepared in accordance with the corresponding standards. 2.6 Supplementary Testing Various supplementary tests are to be carried out only in the order and only in the specified range. Magnetic powder test, ray test, liquid penetrant test and ultrasonic test of cast steel or forgings shall comply with Chapter 8 of ASMEBl6.34 or buyer's own procedures and acceptance criteria, if any. These inspections should be carried out by the valve manufacturer in the presence of the buyer inspector.
