Applications – Where Precise Fracturing Specifications Matter Most

Having accurate, verifiable specifications is critical in these scenarios:

• Deep shale gas (3,500m – 5,000m) – Requires 140+ MPa treating pressure. Standard 105 MPa iron won’t survive. You need SCF8000 specifications with 175 MPa rating.

• HPHT conventional wells – High pressure, high temperature demand fluid end materials rated for thermal cycling and H₂S exposure.

• High‑sand‑volume fracturing – Predicting fluid end life under abrasive conditions requires realistic wear data, not optimistic marketing claims.

• International tenders – Many NOCs and majors demand API 7K/6A certification with full material traceability. Our specification packages meet these requirements.

• Custom equipment design – When standard pumps don’t fit your well profile (non‑standard casing, unusual pressure/rate trade‑off), we develop custom specifications from the ground up.

• Fleet standardization – Large operators need consistent specifications across multiple units to simplify maintenance and spare parts inventory.

Product Types – Fracturing Specifications Packages We Offer

We provide specifications at three levels: standard, engineered, and custom.

1. Standard API 7K Data Sheet (Free with Every Pump)

For our QPA2500, SQP5000, and SCF8000 series, we provide a complete API 7K data sheet including:

• Horsepower vs. pressure curves for all plunger sizes

• Dimensional drawings (mounting, fluid end ports, drive shaft)

• Material certifications (EN 10204 3.1)

• Hydrostatic test certificate

• NDT reports (MT, PT, UT)

• Recommended fluid end service intervals

This is standard documentation – no extra charge.

2. Engineered Specification Package (For Custom Configurations)

When you need a non‑standard plunger size, an upgraded fluid end material, or a specific engine/transmission combination, our engineering team will produce a complete engineered specification package including:

• FEA analysis of pressure‑containing components

• Custom horsepower vs. pressure curves

• Fatigue life prediction (based on your expected cycle profile)

• Certified material test reports for custom alloys

• Third‑party witnessed testing (optional)

Lead time: 4–6 weeks for engineering and documentation.

3. Turnkey Specification Development (For OEM / Private Label)

If you are an equipment distributor or service company wanting to brand our pumps as your own, we can develop complete OEM specification packages under your brand name. Includes:

• Custom part numbers and branding

• Proprietary data sheets (your logo, your formatting)

• Confidentiality agreements

• Dedicated engineering support for your customers

Minimum order quantities apply. Contact our OEM sales team.

4. Digital SOFElink Specification Monitoring

For operators who want to verify specifications in real time, our SOFElink platform continuously compares actual pump performance against rated specifications. Alerts are generated when:

• Packing leakage exceeds specified rate

• Valve impact energy exceeds normal range

• Fluid end temperature exceeds design limit

• Power end vibration suggests bearing wear

This turns a static spec sheet into a dynamic quality control tool.

Frequently Asked Questions (FAQ) – Fracturing Specifications

Q1: What is the difference between "maximum working pressure” and "test pressure” in your specifications?

A: Maximum working pressure (MWP) is the highest continuous pressure at which the equipment is designed to operate under normal conditions. Test pressure is the pressure applied during factory hydrostatic testing – typically 1.5× MWP. For example, our SCF8000 has an MWP of 175 MPa, and each unit is hydrostatically tested to 262.5 MPa before shipment. This 50% safety margin ensures reliable operation at rated pressure.

Q2: How do your horsepower ratings compare to other manufacturers? Are they continuous or peak?

A: We publish continuous horsepower ratings – the power the pump can deliver 24/7 without derating or damage. Many competitors publish peak or intermittent ratings that are 20–30% higher than their continuous capability. If you see a "3,000 HP” pump from another manufacturer, ask for the continuous rating. Our QPA2500 is 2,500 HP continuous; our SCF8000 is 8,000 HP continuous.

Q3: What does "175 MPa” mean in practical terms? Can your equipment actually pump that high?

A: 175 MPa (25,400 PSI) is the maximum continuous working pressure. In field operations, we have pumped the SCF8000 at 140 MPa for hours at a time in Sichuan Basin deep shale wells. The equipment has margin above current field requirements – it is rated for 175 MPa, so you are not operating at the limit. We have also delivered 20,000 PSI (138 MPa) fracturing specifications for HPHT wells in other basins.

Q4: How accurate are your flow rate specifications?

A: Our flow rate specifications are verified on our in‑house test stands using calibrated Coriolis meters and are typically within ±2% of published values. However, actual field flow rate depends on fluid density, suction pressure, fluid end condition, and system backpressure. We provide correction factors in our detailed data sheets.

Q5: What is the expected fluid end life for your heavy duty pumps in abrasive sand fracturing?

A: For the SCF8000 with our second‑generation stainless steel pump head, field data from high‑sand shale operations shows 2,000+ hours between major rebuilds. For the QPA2500 in similar service, typical life is 800–1,200 hours. These numbers are based on actual field records from Sichuan Basin and other shale plays. We provide a fluid end life prediction worksheet with each pump – you input your expected sand concentration, pressure, and rate, and we output an estimated service life.

Q6: Do your specifications include NACE MR0175 compliance for sour gas service?

A: Yes. For H₂S environments, we offer fluid end trims and elastomers that meet NACE MR0175/ISO 15156. The specification package includes material certifications confirming compliance with sour service requirements. Additional H₂S testing (SSC, HIC) is available upon request.

Q7: Can you provide third‑party witnessed testing to verify your specifications?

A: Yes. For an additional fee, we can arrange for third‑party inspection (SGS, BV, DNV, or your nominated agency) to witness pressure testing, dimensional inspection, and performance verification. The witness signs off on our test reports, and the documentation is included in your specification package. This is common for international tenders where independent verification is required.

Q8: What is the pressure rating of your standard 105 MPa equipment vs. your 175 MPa heavy duty line?

A: Our standard QPA2500 is rated to 105 MPa (15,312 PSI) – suitable for most conventional fracturing and shallow shale. Our SCF8000 heavy duty line is rated to 175 MPa (25,400 PSI) – necessary for deep shale (below 3,500m) and HPHT wells. We also offer an intermediate 140 MPa option for certain applications. Choose based on your maximum treating pressure plus a 10–20% safety margin.

Q9: Do you provide custom fracturing specifications for non‑standard plunger sizes?

A: Yes. We have engineered plunger diameters outside our standard 4.0″, 4.5″, 5.0″, 5.5″ range for customers with specific rate/pressure trade‑offs. Custom sizes typically require 8–10 weeks for engineering validation (FEA, test coupon verification, and prototype testing). Minimum order quantities may apply.

Q10: Can I get a specification sheet for a pump I already own (serial number lookup)?

A: Yes. For any SJ Petro fracturing pump manufactured in the last 15 years, we retain as‑built records including material test reports, test certificates, and dimensional reports. Provide the serial number, and we can retrieve the original specification package. For older units, we may have limited records – but we can also perform field verification testing to generate current specifications.
