Drilling 700 – Yuheng

TUBE:

Black, smooth, synthetic NR and NBR rubber.

REINFORCEMENT:

Six steel wire spirals.

COVER:

Corrosion- and weather-resistant synthetic rubber.

TEMPERATURE RANGE:

From -30°C to + 80°C (-22°F to +176°F).

KEY FEATURES:

• Excellent flexibility and pressure resistance, ensuring reliable performance under tough working conditions.
• High wear resistance and long service life, even when conveying abrasive slurries.
• Strong steel wire spiral reinforcement provides superior strength and kink resistance.
• Smooth inner tube minimizes flow resistance and improves delivery efficiency.
• Resistant to oil, weather, and aging for extended outdoor use.
• Suitable for transferring slurry, water, and various fluids at ambient temperature.

APPLICATION & FLUIDS:

Widely used in oil fields, well cementing, geological exploration, drilling operations, and coal mining for conveying slurry, water, and other fluids at ambient temperature.

WORKING PRESSURE:

Maximum working pressures are based on 2:1 safety factor (maximum working pressure to minimum burst pressure).
