Product Types – Specification Packages We Provide

We offer specification documentation at four levels, depending on your needs.

1. Standard Data Sheet (Free with Every Unit Set)

For our standard FUS‑1000, 2000, and 4000 models, we provide a complete data sheet including:

• General arrangement drawing

• Pump performance curves (all plunger sizes)

• Blender sand and liquid rate specifications

• Manifold pressure and temperature ratings

• Control system functional description

• Basic test certificates

2. Engineered Specification Package (For Custom Configurations)

When you need non‑standard components – different plunger sizes, upgraded materials, special coatings – our engineering team produces a custom specification package including:

• FEA analysis of pressure‑containing parts

• 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. Tender Specification Package (For International Bids)

For operators responding to NOC or major oil company tenders, we provide a complete tender documentation package:

• API 7K and 6A data sheets (formatted to tender requirements)

• Full material traceability (EN 10204 3.1)

• NDT reports with inspector certifications

• Third‑party witness test reports (if ordered)

• Compliance matrix (mapping our specifications to tender clauses)

• Letter of conformance

We have supplied tender packages for projects in the Middle East, Russia, Africa, and Southeast Asia.

4. Digital SOFElink Specification (Live Performance Data)

For operators who want to verify specifications in real time, our SOFElink platform continuously compares actual pump performance against rated specifications. The digital spec sheet includes:

• Live horsepower vs. pressure overlay

• Real‑time fluid end wear estimation

• Alerts when actual performance deviates from spec

• Historical trend analysis

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

Applications – Where Precise Fracturing Unit Set Specifications Matter

Accurate, verifiable specifications are critical in these scenarios:

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

• HPHT conventional wells – High pressure demands fluid end materials rated for thermal cycling and H₂S exposure.

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

• International tenders – NOCs and majors demand API 7K/6A certification with full material traceability.

• Pad layout and logistics planning – Dimensional drawings are essential for crane lifts, transport, and safety clearances.

• Fleet standardization – Large operators need consistent specifications across multiple unit sets to simplify maintenance and spares.

Why Choose SJ Petro for Fracturing Unit Set Specifications?

Because our specifications are not marketing. They are engineering data, verified by test stands and field records.

Your Specification Need	SJ Petro’s Answer

Frequently Asked Questions (FAQ) – Fracturing Unit Set 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: 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.

Q4: What is the expected fluid end life for your unit sets in abrasive sand fracturing?

A: For the SCF8000 with second‑generation stainless steel pump head: 2,000+ hours between major rebuilds. For the QPA2500 in similar service: 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 specification package – you input your expected sand concentration, pressure, and rate, and we output an estimated service life.

Q5: 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.

Q6: 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.

Q7: What is the dimensional envelope for a standard FUS‑2000 unit set?

A: For a diesel FUS‑2000 (4 × QPA2500 skids, 1 blender, 1 manifold skid, 1 data van, loose iron):

Component	Length	Width	Height	Weight
Each pump skid	5.5m	2.5m	2.8m	18 t
Blender skid	7.5m	2.5m	3.5m	15 t
Manifold skid	6.0m	2.2m	1.2m	8 t
Data van	6.0m	2.5m	2.8m	6 t

Rigged up footprint (all components positioned): approximately 25m × 15m. Complete dimensional drawings are available upon request.

Q8: Do you provide custom 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.

Q9: Can I get a specification sheet for a unit set I already own (serial number lookup)?

A: Yes. For any SJ Petro fracturing unit set manufactured in the last 15 years, we retain as‑built records including material test reports, test certificates, and dimensional reports. Provide the serial number of the main pump or unit set ID, 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.
