Packaging, transportation and delivery
Packaging, transportation and delivery
At Hebei Huayang Steel Pipe Co., Ltd., we apply standardized and reliable packaging solutions for all our steel pipe products. Our pipes can be securely packed by hexagonal bundling or circular bundling according to product diameter, wall thickness and customer requirements. Each pipe end is protected with high‑strength plastic pipe caps to avoid collision damage, dust and moisture during transportation and storage. The whole bundle is firmly wrapped with durable woven bags to enhance stability and prevent scratches or deformation.
We support a complete range of transportation methods to satisfy global customers, including road transportation, railway transportation, sea freight and container shipping. Based on our strategic location in Cangzhou, Hebei Province, we enjoy convenient access to major ports such as Tianjin Port, which greatly improves logistics efficiency and reduces transportation costs.
For standard specifications and normal order quantities, the general delivery time is about 30 days after order confirmation and deposit receipt. For large‑scale orders, special sizes or customized processing requirements, our production and sales team will formulate a detailed production plan and provide an accurate delivery schedule accordingly to ensure on‑time supply and stable performance for projects and clients worldwide.
Strict quality control
1. During and after the production, experienced quality inspectors randomly check the products to ensure that each steel pipe is qualified for production and application.
2. A nationally recognized laboratory with CNAS certification and certification by French Classification Society.
3. Have CNOOC access certificate, KOC oil company access network, ADNOC Abu Dhabi oil company access network, Petrobras access network, etc.
4. Accept the inspection by the third party designated/paid by the buyer, such as SGS and BV.
