Production Capacity: 100,000 tons per year

Production Cycle, Packaging, Delivery
Production cycle of our API 5L seamless steel pipes is about 2 weeks. This ensures in-time delivery. If there are no special requirements, we will deliver the seamless line pipes by simple bundling without other package. If required, we can also offer export packaging to match your needs.

Raw Materials
The seamless steel tubes are all made from superior steels supplied by Tianjin Iron and Steel Co., Ltd. This is only for the reliable steel pipe quality.
