Zhongtong operates a 24-hour in-house testing laboratory equipped with tensile testing machines, hydrostatic pressure testing equipment, and instruments for dimensional and physical performance testing.

Testing is arranged according to the product and project requirements and may cover outside diameter, wall thickness, length, dimensional accuracy, surface appearance, pipe ends, tensile properties, hydrostatic pressure performance, product markings, batch information, and other specified items.

The factory has a large outdoor storage area with a capacity of over 10,000 tons. Pipes are organized by product type, diameter, and specification, making inventory management and product identification more efficient.

During storage, quality personnel conduct regular spot checks to review product appearance, markings, and storage condition.

Zhongtong uses CAD software to plan container loading based on pipe diameter, length, quantity, and container dimensions.

By optimizing product arrangement and loading configuration, we improve container space utilization while reducing unnecessary movement, compression, deformation, and surface damage during transportation. The loading plan also helps control international shipping costs and improves the efficiency of quantity and specification verification before shipment.
