2-Inch 15,000 psi Acid Fracturing Hose: Acid-Resistant, High-Pressure, Long-Life
1. Why This Hose is Needed?
Acid fracturing often uses strong acids like 28% hydrochloric acid. Ordinary rubber inner tubes swell and fail within minutes. Meanwhile, a 2-inch bore must withstand 15,000 psi ultra-high pressure and highly abrasive fluids containing proppants. This places extreme demands on the hose material. The 2-inch 15,000 psi acid fracturing hose solves three challenges at once: acid resistance, high pressure resistance, and wear resistance.
2. Key Parameters
| Parameter | Value |
|---|---|
| Inner Diameter | 2 inches (approx. 51 mm) |
| Working Pressure | 15,000 psi (≈1,034 bar) |
| Burst Pressure | ≥ 4 × working pressure (≥60,000 psi) |
| Safety Factor | 4:1 |
| Temperature Range | -29°C to +100°C |
| Min. Bend Radius | ≤1,000 mm |
| Standards | API 7K FSL0, ABS certified |
2 inches is the mainstream size for acid fracturing, balancing flow rate and layout flexibility.
3. Simple Structure Analysis
-
Inner Tube: Imported UPE (Ultra-High Molecular Weight Polyethylene) + synthetic rubber.
-
Resists 28% hydrochloric acid, hydrofluoric acid, etc. – no swelling.
-
Abrasion resistance is 5 times that of ordinary rubber, abrasion resistance increased by 300%, withstands quartz sand erosion for 800 hours.
-
-
Reinforcement Layer: 4–6 layers of high-strength, super-flexible steel wire spiral wound.
-
Withstands 15,000 psi ultra-high pressure, 4:1 safety factor, anti-burst and anti-impulse.
-
-
Outer Cover: Abrasion- and weather-resistant synthetic rubber.
-
Resists scratching, ozone, and UV, protecting the internal steel wires.
-
4. Core Advantages
-
Superior Acid Resistance – UPE inner tube safely conveys 28% hydrochloric acid and other strong acids, eliminating swelling failure of conventional hoses.
-
Excellent Wear Resistance – UPE has more than 5 times the abrasion resistance of ordinary rubber; service life in sand fracturing is extended 3–5 times.
-
High Safety Margin – 4:1 safety factor, integrated crimped couplings – no leakage or pull‑out.
-
Multi‑fluid Compatibility – One hose handles water‑based, oil‑based, foam, and acid‑based fracturing fluids.
-
70% Weight Reduction – Compared to steel pipes, installation efficiency increases by 80%, and the hose absorbs vibration to protect equipment.
5. Typical Applications & Selection Guide
| Application | Advantage |
|---|---|
| Acid fracturing (28% HCl) | UPE inner tube resists strong acids |
| Sand fracturing (silica sand/ceramic proppants) | UPE ultra‑wear‑resistant, life extended by 300% |
| Water fracturing | Multi‑layer steel wires ensure stable pressure |
| Shale gas horizontal well stage fracturing | Small bend radius, flexible installation |
Selection tips:
-
Ensure the inner tube is UPE material and verify its compatibility with the specific acid type and concentration.
-
Recommend using API 16C quick‑connect couplings or integral union assemblies, factory crimped and pressure‑tested.
-
Keep operating temperature within -29°C to +100°C.
6. Conclusion
The 2-inch 15,000 psi acid fracturing hose, with its UPE ultra‑wear‑resistant inner tube, 4–6 layers of steel wire reinforcement, and 4:1 safety factor, solves the triple challenge of high pressure, strong acid, and severe abrasion in one integrated design. Choosing a hose certified to API 7K and ABS with a UPE inner tube is a smart decision for safe, efficient, and low‑cost acid fracturing operations.
