ANSI/AWWA C200-23美标钢制水管的检验内容：买方可检查根据ANSI/AWWA C200-23《6英寸（150毫米）及以上钢制水管》美国水工程协会标准要求完成的工作和提供的材料，但此类检查不应免除制造商根据本标准提供材料和执行工作的责任。如果买方希望检查管道或见证测试，制造商应就检查时间发出合理通知。1、质量保证：制造商应保持质量保证计划，以确保达到最低标准。它应包括一个CWI，以验证焊工和焊接程序是否合格，在测试范围内是否遵循了程序，以及是否实施了质量保证功能。2、通道和设施：买方应有权在合理的时间访问制造商工厂中与买方订购的材料制造有关的部分。制造商应向买方提供必要的设施，以确定材料是否在按照这个标准。装运前，应在制造地进行测试和检查。3、管道更换：买方可以拒绝任何不符合规定测试结果和公差的管段或特殊管段。拒收的管道可根据ANSI/AWWA C200-23《6英寸（150毫米）及以上钢制水管》美国水工程协会标准中第4.7.3节进行维修或更换。4、制造商售后：如果材料在工厂检查时或在制造商工厂验收后存在不可接受的缺陷，或者在正确安装和使用时被证明有缺陷，则可能会拒收材料并通知制造商。如果在选择材料或壁厚时出现此类缺陷或错误，制造商应修理或更换此类材料。5、交付：对于交付目的地的成品管道，买方应在卸货前后检查在交货目的地收到的货物是否符合要求。任何在交付时出现凹痕或扭结的管段或特殊管段都可能被拒收。提单上应注明损坏情况和拒收原因，并由承运人代表草签。制造商应在买方批准的情况下修理或更换被拒收的部分。6、修复：不合格钢管材料的修复应通过重新轧制或压力完成，而不是通过锤击。如果买方认为有必要，修复后的管道材料应在所需压力下重新进行静水压试验。

The inspection content of ANSI/AWWA C200-23 American standard steel water pipes: The buyer may inspect the work completed and materials provided in accordance with the American Water Engineering Association standard requirements of ANSI/AWWA C200-23 "Steel Water Pipes 6 inches (150 mm) and above", but such inspection shall not exempt the manufacturer from the responsibility of providing materials and performing work in accordance with this standard. If the buyer wishes to inspect the pipeline or witness testing, the manufacturer shall provide reasonable notice of the inspection time. 1. Quality Assurance: Manufacturers should maintain a quality assurance plan to ensure compliance with minimum standards. It should include a CWI to verify the qualification of welders and welding procedures, compliance with procedures within the testing scope, and implementation of quality assurance functions. 2. Channels and facilities: The buyer shall have the right to access the parts of the manufacturer's factory related to the manufacture of the materials ordered by the buyer at reasonable times. The manufacturer shall provide the necessary facilities to the buyer to determine whether the materials comply with this standard. Before shipment, testing and inspection should be conducted at the manufacturing site. 3. Pipeline replacement: The buyer may reject any pipe section or special pipe section that does not meet the specified test results and tolerances. Rejected pipelines can be repaired or replaced in accordance with Section 4.7.3 of the American Water Engineering Association standard, ANSI/AWWA C200-23 "Steel Water Pipes 6 inches (150 millimeters) and above". 4. Manufacturer's after-sales service: If the material has unacceptable defects during factory inspection or after acceptance at the manufacturer's factory, or is proven to have defects during proper installation and use, the material may be rejected and the manufacturer notified. If such defects or errors occur in the selection of materials or wall thickness, the manufacturer should repair or replace such materials. 5. Delivery: For the finished pipeline at the delivery destination, the buyer shall inspect whether the goods received at the delivery destination meet the requirements before and after unloading. Any pipe section or special pipe section that shows dents or knots during delivery may be rejected. The bill of lading should indicate the damage and reason for rejection, and be signed by the carrier's representative. The manufacturer shall repair or replace the rejected parts with the approval of the buyer. 6. Repair: The repair of non-conforming steel pipe materials should be completed by re rolling or pressure, rather than by hammering. If the buyer deems it necessary, the repaired pipeline material should undergo a hydrostatic pressure test again at the required pressure
