ANSI/AWWA C200-23 standard spiral welded pipe delivery requirements: Section 1: Marking: Serial numbers or other identification marks should be applied in prominent positions on each section of the pipeline and each special section of the pipeline. If the pipeline has a coating or lining, such markings should be transferred to the coating or lining. Manufacturers may need to provide the buyer with a circuit diagram or laying schedule showing the location of each numbered pipe or special section within the pipe. The numbers on such charts or schedules should correspond to the numbers on pipelines and special sections. Section 2: Handling and Loading: 1. The transportation and handling of coated or lined pipelines shall comply with the requirements of the buyer's documents. If there are no buyer's documents, they shall comply with the recommendations of the pipeline manufacturer. Appropriate equipment should be used to handle pipelines and prevent deformation or damage. Hooks or clamps that may cause twisting or bending of the ends are not allowed. The loading method should prevent any protrusions on the length of the pipeline, such as the end with overlapping joints or the end of the bell and faucet with rubber gasket joints, from rubbing against each other or against another section of the pipeline. 2. Non roundness. The loading of pipelines should ensure that the roundness does not exceed the limit specified by the buyer. Section 3: Compliance Oath: The buyer may request the manufacturer to provide an affidavit stating that the pipes, special parts, and other products or materials provided under the buyer's documents comply with all applicable provisions of this standard.
