Aogang Machinery Co., Ltd.
The customer is a Mexican oil industry enterprise serving the oil and gas sector. To supply its pipe manufacturing facility with high-quality slit strip steel, they procured a customized high-speed slitting line from Aogang. The equipment was designed to meet three core requirements:
High production capacity: Continuous strip supply for two pipe production lines
High precision: Ensure consistent quality and dimensional accuracy of pipes for oil and gas transmission
High reliability: Minimize downtime, maintain uninterrupted production, and ensure supply chain stability
Continuous high-speed operation since commissioning
Near-zero unplanned downtime, significantly reducing maintenance frequency and operational costs
Fully meets the oil & gas industry’s strict requirements for equipment reliability and delivery consistency
Dual slitter head system enables back-to-back changeovers with two independent slitting units
Reduces tooling change time by approximately 66%, greatly improving equipment utilization and flexibility
Allows fast adaptation to multiple pipe size production needs
Designed for high-speed mass production
Slitting width accuracy: ±0.1 mm, burr height ≤ 0.03 mm
Consistent precision ensures welding quality and dimensional stability in downstream pipe forming
Max raw material width: 1850 mm, compatible with various oil & gas pipe dimensions
Designed annual output (single shift): approx. 70,000 tons, fully covers internal supply
Surplus capacity enables commercial sales of slit coils, creating additional revenue streams
Parameters can be customized according to customer requirements.
