Description:
Minerza DTH pipes are engineered for precision, durability, and compatibility across all DTH systems. Manufactured from cold-drawn seamless N80-grade steel, each pipe undergoes strict dimensional and straightness control to ensure flawless alignment and maximum torque transfer. The advanced surface treatment provides superior resistance to fatigue, while optimized wall thickness guarantees consistent air flow and mechanical strength. Designed for both surface and underground operations, FlowLine pipes deliver smooth drilling performance, reduced vibration, and extended service life.
