Application Fields – Where Our Solutions Operate

🛢️ Land Drilling (Conventional & Unconventional)

From vertical wells in West Texas to multi‑well pads in the Sichuan Basin, our drilling mud manifolds and choke & kill systems are standard equipment on many rigs. The only Class A manufacturer of choke and kill manifolds for CNPC, we supply systems for wells up to 9,000 meters depth.

💥 Hydraulic Fracturing (Shale, Tight Gas, CBM)

Our fracturing manifold skids are designed for high‑rate, high‑pressure stimulation. Dual‑channel and triple‑channel configurations handle pump rates up to 100 bbl/min (16 m³/min) at 15,000 psi. We have supplied fracturing manifolds for shale operations in the Permian Basin, Vaca Muerta, and Xinjiang.

🌊 Offshore Platforms & Jack‑Up Rigs

SJ Petro has supplied complete fluid control solutions to offshore platforms operated by Phillips, Kerr‑McGee, Nanbao, and Weizhou, as well as the Luda 6000m modular rig and offshore rigs exported to Cuba. Our subsea choke and kill systems meet API 16C for deepwater BOP stacks.

🧊 Arctic & Permafrost Drilling (Siberia, Northern Canada)

With 11 low‑temperature drilling rigs delivered to Rosneft and three ZJ40 cold‑weather rigs to Orienburg Drilling Company, we have extensive experience in -45°C operations. Our Arctic‑rated fluid control solutions use low‑temperature steel, cold‑hardened elastomers, and heated valve actuators — all tested in our national‑level low‑temperature impact laboratory.

⚡ High‑Temperature & Thermal Recovery

For steam injection wells and geothermal drilling, our Y‑class manifolds withstand temperatures up to +345°C (650°F). We use special alloys (Inconel, Monel) and high‑temperature seals for long‑term reliability.

🔧 Well Intervention & Workover

Coiled tubing and workover operations need compact, portable fluid control systems. Our lightweight cementing and stimulation manifolds are skid‑mounted for easy truck transport.

Why Choose SJ Petro for Fluid Control Solutions?

🏭 Class A Manufacturer – The CNPC Distinction

SJ Petro is the only Class A manufacturer of choke and kill manifolds for CNPC — a rating based on rigorous quality audits, field performance, and manufacturing capability. This distinction is not awarded lightly. It reflects decades of reliable service to China’s largest oil and gas operator.

✅ API 6A & 16C Certified – Full Traceability

We hold API 6A (wellhead/tree), API 16C (choke/kill), API Q1, and multiple other certifications. Every material is traceable. Every weld is inspected. Every pressure test is recorded. Our documentation meets international requirements for export to any market.

🔧 One‑Stop Engineering – From Valves to Skids

You can buy a plug valve from any supplier. But a complete, integrated fluid control solution requires engineering coordination. We provide:

• System design – Flow analysis, pressure drop calculation, stress simulation

• Component selection – Valves, connections, chokes, gauges, actuators

• Skid fabrication – Structural steel, lifting points, labeling, painting

• Pre‑commissioning – Hydrostatic testing, function testing, documentation

• On‑site support – Installation supervision, training, and spare parts

🌍 Global Compatibility – Interchangeable with Major Brands

Our fluid control solutions are designed to be dimensionally and functionally interchangeable with world‑leading American manifolds (SPM, FMC, NOV). Whether you are replacing components in an existing field or integrating with international equipment, our systems fit without re‑engineering.

📋 Proven Export Track Record – 30+ Countries

We have supplied fluid control solutions to oilfields in Russia, Kazakhstan, the Middle East, the United States, Canada, Cuba, and across China. Our export documentation team handles customs clearance, third‑party inspections (DNV, BV, ABS), and GOST certifications for Russian/Eurasian markets.

🧪 National‑Level Low‑Temperature Testing

Our national‑level low‑temperature impact testing laboratory qualifies materials down to -60°C. For Arctic solutions, we do not guess — we test. This capability is unique among Chinese fluid control manufacturers.

Frequently Asked Questions (FAQ)

Q1: What is the difference between a fluid control "component” and a "solution”?

A: A component is a single part — a plug valve, a check valve, a union. A solution is an engineered assembly of components designed for a specific application. For example, a fracturing manifold skid includes plug valves, check valves, swivel joints, pressure gauges, bleed valves, and interconnecting piping — all mounted on a steel skid with lifting points. The solution arrives at your wellsite ready to connect to pumps and wellhead. You do not have to design the layout or source individual parts.

Q2: Do your fluid control solutions meet API 6A and API 16C?

A: Yes. All our high‑pressure fluid control products are manufactured to API 6A (wellhead and tree equipment) and API 16C (choke and kill systems). We hold current API certifications and are subject to regular audits. We can supply API monogrammed products upon request.

Q3: Can you design a manifold for my specific pump configuration?

A: Absolutely. We regularly design manifolds for 2‑pump, 4‑pump, 6‑pump, and larger fleets. Provide us with the number of pumps, their discharge flange sizes and pressure ratings, and the wellhead connection specification. We will design a manifold that balances flow evenly across all pumps and minimizes pressure drop.

Q4: What pressure ratings are available for fracturing manifolds?

A: Our standard fracturing manifold skids are rated for 10,000 psi, 15,000 psi, and 20,000 psi (70, 105, and 140 MPa) . For operations with pump pressure consistently below 13,500 psi (93 MPa), the 15,000 psi rating is typical. For deeper wells or higher treating pressures, we supply 20,000 psi systems.

Q5: Are your fluid control solutions compatible with equipment from other manufacturers?

A: Yes. Our high‑pressure connections (Fig 1502, Fig 2002, Fig 206, API 6A flanges) are dimensionally identical to industry standards. We can connect directly to pumps, wellheads, and BOPs from American, European, and other Chinese manufacturers. For sour service and HP/HT compatibility, we match or exceed OEM specifications.

Q6: What is the lead time for a custom manifold skid?

A: For a standard design (e.g., dual‑channel fracturing skid, 15,000 psi, 4″ bore), lead time is 12–14 weeks from order confirmation. For complex custom designs with special alloys or subsea ratings, allow 16–20 weeks. We maintain limited inventory of standard manifolds for emergency replacement — contact us for current availability.

Q7: Do you provide on‑site commissioning for fluid control solutions?

A: Yes. For custom and skid‑mounted solutions, we include on‑site commissioning by one of our manifold engineers (travel expenses extra). The engineer verifies connections, performs pressure testing (if not already done at factory), trains your crew on operation and maintenance, and provides a commissioning report. Typically 3–5 days on site.

Q8: How do I request a quote for a fluid control solution?

A: Please provide the following information to our sales team:

1. Application (drilling, fracturing, well testing, etc.)

2. Maximum working pressure (psi or MPa)

3. Bore size(s) needed

4. Number of pump connections (if manifold)

5. Connection types (Fig 1502, API flange, etc.)

6. Wellhead/equipment interface details

7. Environmental conditions (temperature range, H₂S/CO₂ content)

8. Any specific material or certification requirements

We will respond within 3–5 business days with a technical proposal and quotation.

Q9: Do you supply spare parts kits for your fluid control solutions?

A: Yes. We recommend a first‑line spare parts kit containing:

• Replacement seal kits for all plug valves and chokes

• Extra choke beans (if fixed choke)

• Pressure gauge (liquid‑filled, 4″)

• Bleed valve and plug

• Union gaskets (Fig 1502 / 2002)

The kit is customized based on your manifold configuration. We can also provide a recommended inventory for remote field locations.

Q10: What is your warranty policy?

A: Standard warranty is 12 months from shipment against defects in material and workmanship. Warranty covers repair or replacement of defective components; it does not cover normal wear (seals, choke beans), erosion from abrasive fluids exceeding specified limits, or damage from misapplication.
