Haohe lists MPP ducts for communication and power-cable routes; request the selected size, joint arrangement and project specification.
Provide the intended fluid or service, required material, dimensions and joining arrangement. Ask for the actual pipe specification and supporting material and installation documents, rather than assuming one polymer or pressure class from the general company scope. Request the current catalogue or drawing for this item, and confirm the offered configuration and supporting documents with the company before specifying an order.
