Parts Classification for Load Guyline Regulator Z04220000001AA

1

Regulator of load guyline

Z04220000001AA

High-strength alloy steel (Q355B), surface galvanized

1. Fatigue from repeated tension adjustments; 2. Corrosion from outdoor humid/dusty environments; 3. Wear at internal adjustment mechanisms.

1. Lubricate internal components quarterly with extreme-pressure grease; 2. Inspect tension adjustment precision monthly; 3. Touch up galvanized coating annually to prevent corrosion.

2

Fixed pipe assembly

Z04220100001AA

Seamless carbon steel pipe (20# steel), anti-corrosion coated

1. Impact damage during installation/transport; 2. Corrosion from drilling fluid splashes; 3. Stress deformation from uneven tension.

1. Use protective sleeves during transport to avoid impact; 2. Clean drilling fluid residues weekly; 3. Inspect for bending deformation monthly, correct promptly.

Bolt, grommet

P1200178AA

High-strength alloy steel (10.9 grade), galvanized

1. Thread wear from repeated assembly/disassembly; 2. Loosening from long-term drilling vibration; 3. Corrosion at thread roots.

1. Tighten to rated torque (45-50N·m) with a calibrated wrench; 2. Apply anti-rust thread compound before installation; 3. Replace after 4-5 assembly cycles.

2

Locking nut

Z04220300001AA

Carbon steel (8 grade), galvanized with nylon insert

1. Nylon insert wear leading to loss of locking function; 2. Thread corrosion; 3. Deformation from over-tightening.

1. Inspect nylon insert elasticity quarterly, replace if worn; 2. Avoid over-tightening to prevent thread deformation; 3. Store in dry environment to avoid corrosion.

3

Wheel shape nut

P2000110AA

Carbon structural steel (Q235A), galvanized

1. Wear at wrench contact points; 2. Thread damage from improper installation; 3. Corrosion from outdoor exposure.

1. Use matching wrenches to avoid slipping and wear; 2. Install evenly to prevent thread misalignment; 3. Apply anti-corrosion grease to threads monthly.

1

Safety pin

P6400243AA

Spring steel (65Mn), surface chrome-plated

1. Fatigue from repeated insertion/extraction; 2. Corrosion leading to reduced elasticity; 3. Bending deformation from improper force application.

1. Insert/extract gently to avoid bending; 2. Apply anti-rust oil quarterly; 3. Inspect for fatigue cracks monthly, replace if present.

2

Stopper 15X25

P6400244AA

Rubber (NBR), reinforced with steel core

1. Aging from outdoor temperature changes; 2. Abrasion from repeated contact with components; 3. Damage from impact.

1. Inspect for cracks/aging quarterly, replace if needed; 2. Avoid direct impact during operation; 3. Store away from high-temperature environments to slow aging.

3

Stopper 90X20

P6400244AA

Rubber (NBR), reinforced with steel core

1. Compression fatigue from long-term contact; 2. Abrasion from component movement; 3. Corrosion of internal steel core in humid environments.

1. Rotate stoppers periodically to reduce localized compression; 2. Clean surface debris weekly to reduce abrasion; 3. Replace if rubber hardening or steel core corrosion is detected.

1

What standards apply to the Z04220000001AA load guyline regulator, and how to verify part quality?

Comply with API Spec 4F and GB/T 5972-2016. Verify material certificates for alloy steel components, check galvanization thickness, and confirm fasteners meet GB/T 3098.1-2010 strength requirements.

2

How often should safety pins (P6400243AA) and stoppers be replaced under normal drilling conditions?

Replace safety pins every 1200 working hours or if fatigue cracks are found. Replace rubber stoppers every 800 working hours, or immediately if aging, cracking, or steel core corrosion is detected.

3

How to prevent fastener loosening in the load guyline regulator system?

Use nylon-insert locking nuts, apply anti-rust thread compound, tighten to rated torque with a calibrated wrench. Inspect fastener tightness weekly, retighten if loose, and replace worn bolts/nuts promptly.
