Applications
Our automatic pipe handling systems are deployed across:
| Application | Key Components | Benefit |
|---|---|---|
| Land drilling rigs (5,000‑9,000m) | Full system (catwalk + roughneck + racking) | Reduce crew size, increase ROP |
| Workover rigs (well servicing) | Catwalk + iron roughneck | Fast tubing trips, less manual handling |
| Offshore jack‑up / platform | Corrosion‑protected system, compact design | Limited floor space, remote operation |
| Shale gas multi‑well pads | Truck‑portable catwalk, quick‑disconnect | Fast rig‑up between wells |
| Deep well HPHT drilling | High‑torque roughneck (160k ft‑lbs) | Reliable makeup on large tool joints |
| Abandonment / P&A campaigns | Full system | Long tripping sequences, reduce crew fatigue |
Product Types – Automation Level
We offer three automation tiers to match your operational needs and budget:
| Tier | Components Included | Automation Level | Typical Crew Reduction |
|---|---|---|---|
| Semi‑Auto (Basic) | Hydraulic catwalk + iron roughneck | Remote control (wired or wireless). Operator initiates each step. | 1‑2 people |
| Full‑Auto (Advanced) | Catwalk + roughneck + racking system + unified console | Pre‑programmed sequences. One operator runs entire trip from console. | 2‑3 people |
| Hands‑Free (Premium) | Full system + AI sequence optimization + remote cabin | One‑button trip cycle. No personnel on rig floor during tripping. | 3‑4 people |
All systems can be retrofitted to existing rigs (skid‑mounted, no major structural changes). We provide on‑site installation and operator training.
Why Choose SJ Petro for Your Automatic Pipe Handling System?
1. Proven Field Results – Operators report 25–30% faster tripping speeds and 50‑70% reduction in rig floor personnel after installing our systems.
2. API 7K Certified – All components designed and tested to API 7K with minimum 2.25:1 safety factor. Third‑party witness available.
3. Custom Designed for Your Rig – We do not sell "standard” systems. Our engineering team measures your rig floor, derrick layout, and pipe sizes – then builds a system that fits perfectly.
4. Fast Installation – Skid‑mounted modules bolt onto existing rig floor with minimal welding. Typical installation: 5–10 days for a full system.
5. Single‑Source Integration – Catwalk, roughneck, racking, and controls – all from one supplier. No finger‑pointing when something needs support.
6. Remote Diagnostics – Our control system allows us to log into your PLC (with your permission) and troubleshoot faults without a site visit.
7. Global Spares Network – Critical parts (jaws, hydraulic valves, sensors) stocked in Houston, Dubai, and Singapore. 48‑hour emergency air freight.
8. Sinopec Engineering Backing – Decades of drilling experience behind every design. We know what breaks – and have fixed it.
Frequently Asked Questions (FAQ)
Q1: What is the difference between an automatic pipe handling system and a manual system?
Manual systems require crew members to push, pull, and roll pipe across the rig floor – high injury risk and slow. Automatic systems use hydraulic catwalks, iron roughnecks, and racking to move pipe without hands‑on handling.
Q2: Can this system be retrofitted to my existing rig?
Yes. We supply bolt‑on modules (catwalk, iron roughneck, racking) that fit most land and platform rigs. A site survey is required to confirm dimensions.
Q3: How fast can the system trip pipe?
Full‑auto systems achieve 25–30 stands per hour (depending on depth and crew experience). Manual systems typically achieve 15–18 stands per hour.
Q4: How many people are needed to operate the system?
Semi‑auto: 3‑4 total (operator + assistant + floor hand). Full‑auto: 2‑3 total (operator + one helper). Hands‑free: 1 operator in remote cabin.
Q5: What is the maximum pipe size the system can handle?
Catwalk handles up to 20″ casing. Iron roughneck handles up to 11″ OD tool joints. Racking system handles stands of 2‑3 joints of 5‑1/2″ DP (or equivalent).
Q6: How accurate is the iron roughneck torque control?
±2% of setpoint. Digital torque display and data logging allow you to verify every connection and comply with torque turn requirements.
Q7: Do you provide training for the system?
Yes – 3‑5 days on‑site training covering operation, maintenance, safety procedures, and emergency handling. Simulator training available at our facility.
Q8: What is the typical lead time for a custom automatic pipe handling system?
Semi‑auto systems: 4‑6 months. Full‑auto systems: 6‑8 months. Hands‑free premium systems: 8‑10 months. Retrofit kits ship faster (3‑4 months).
Q9: Does the system work in extreme temperatures?
Yes – arctic package down to -40°C (heated hydraulic oil, low‑temp seals). Desert package up to 55°C (oversized coolers, dust filters).
Q10: What certifications do your systems carry?
API 7K (components). SY/T 7421‑2018 compliance for automatic pipe string processing systems. CE and ATEX available on request.
Q11: How do you ensure safety if the system loses power?
All hydraulic cylinders have integral holding valves – the load stays in place if pressure drops. Manual override pumps and backup accumulators allow safe recovery.
Q12: How do I get a quote for an automatic pipe handling system?
Provide: rig type (drilling/workover), pipe size range, desired automation level (semi‑auto / full‑auto / hands‑free), current tripping speed (optional). We will respond with a system proposal and fixed price within 10 business days.
