Before placing an order, verify the exact thread compatibility with your pipe inventory, as IF/NC50 protectors must match the thread profile precisely to avoid damage. Confirm the material grade and surface treatment to ensure it meets your environmental and operational requirements, especially for offshore or high-corrosion applications.
Logistics details such as lead time, packaging options, and Incoterms should be clarified with Shaanxi Senwell Drilling Equipment Co., Ltd. Bulk shipments are typically palletized or crated, but confirm whether the supplier can accommodate your preferred packaging for international transport. Request FOB or CIF terms based on your preferred port of discharge in China.
For quality assurance, inspect a sample batch for dimensional accuracy, material composition, and surface treatment integrity. Check that the protectors meet API standards and request a mill test certificate or third-party inspection report if required. Documentation such as packing lists, commercial invoices, and API compliance certificates should accompany the shipment.
