1. Industry Trend: β-PPH Grows as Core Track in Plastic Pipe Industry
1.1 Industry Shift: From Volume Competition to Technical R&D
Most plastic pipe sectors now face overcapacity and cutthroat low-price competition. Meanwhile, new energy, chemical and pharmaceutical industries impose stricter stability standards for process piping. Manufacturers must compete on raw material control, precision production and finished-product testing, creating sustained market demand for premium β-PPH piping.

1.2 Critical Defects of Conventional α-PPH
Three obvious drawbacks limit α-PPH for harsh industrial conditions:
Low heat resistance: Long-term service temperature capped at 80°C; thermal creep easily occurs under temperature fluctuation, destabilizing pipeline systems.
Poor low-temperature toughness: Impact strength drops sharply below 5°C, prone to cracking under collision or thermal stress with major safety risks in cold weather construction.
Weak long-term pressure resistance: Long-term transport of high-pressure corrosive fluids causes stress cracking and joint leakage, only fit for mild-corrosion, room-temperature simple projects.
Modified with beta crystal structure, β-PPH outperforms α-PPH comprehensively in heat resistance, impact resistance and anti-corrosion, and is widely adopted in industrial projects year by year.
2. Technical Comparison: α-PPH vs β-PPH
2.1 Crystal Structure Difference
α-PPH: Brittle molecular structure, easy to deform and crack under temperature variation or long pressure load.
β-PPH: Optimized beta crystal arrangement with outstanding stress buffer capacity, stable performance across high & low temperature cycles.
2.2 Key Performance & Application Comparison
Comparison Item α-PPH β-PPH
Continuous Operating Temp ≤80℃，
prone to creep with temperature swings ≤95℃，
stable under heat cycles
Heat Deflection Temp ≈95℃ ≈108℃
Tensile Yield Strength ≥23MPa ≥28MPa
Notched Izod Impact (0°C) 3.2kJ/㎡ 7.1kJ/㎡
Oxidation Induction Time（210℃） ≥10min ≥20min
Applicable Standard GB/T18742 (building water supply) QB/T 5099.1-2017
Acid & Alkali Resistance Short-term delivery of low-concentration mild corrosives Long-term transport of high-concentration acids & alkalis
Typical Applications Civil water supply, small-scale simple wastewater treatment Lithium battery, pharmaceutical, large chemical complete anti-corrosion pipeline projects
As can be seen from the data,α-PPH fits basic low-standard scenarios, while balanced high-performance β-PPH dominates high-spec industrial engineering.
3. Five Unique Competitive Advantages of Jiangsu Jiqing Pipe Group
3.1 Raw Material & Testing Technology Barrier
We exclusively adopt 100% virgin homopolymer polypropylene with proprietary beta modification formula, without any recycled additives.
Every batch undergoes in-house lab inspection plus third-party authoritative re-testing to guarantee consistent product performance.

3.2 Intelligent Precision Production Process Barrier
β-PPH production demands tight control over heating, cooling and traction speed. Jiqing deploys clustered automated production lines managed by central control system to eliminate batch quality deviation and stabilize mass output quality.
3.3 Closed-Loop Full-Range Quality Control Barrier
An independent professional testing lab implements full-process inspection:
Raw material entry: Purity & melt flow rate testing
In-line production: Real-time outer diameter & wall thickness monitoring
Finished goods: Hydrostatic, impact and corrosion resistance tests
All test records are archived completely, fully meeting acceptance standards for large industrial projects.

3.4 Complete Full-Spec Piping Matching Barrier
Many small manufacturers only supply bare pipes; mismatched fittings from separate suppliers cause connection leakage risks.
Jiqing achieves annual output of 15,000 tons, self-producing DN15–DN1200 pipes, fittings, valves and custom non-standard components. Identical raw materials and manufacturing processes ensure perfect welding compatibility for one-stop pipeline procurement.

3.5 Full-Cycle Custom Engineering Service Barrier
With abundant delivered projects in chemical, new energy and wastewater sectors, our technical team provides end-to-end support:
Pre-project: β-PPH material selection & pipeline layout design support
Construction: On-site professional welding guidance
Post-operation: Regular pipeline inspection & follow-up visits
Extreme working conditions: Custom thickened pipes & special fittings for tailored anti-corrosion solutions
4. Industry Value: Jiqing Drives High-Quality β-PPH Development
4.1 Standardized Quality Benchmark
Many manufacturers cut corners on raw materials and production procedures, leading to frequent pipeline failures. Jiqing maintains three core standards: virgin raw material, intelligent standardized production and dual-layer inspection, setting reliable industry benchmarks and promoting standardized development.

4.2 Professional Technical Support for Material Selection
Most design institutes and construction teams cannot accurately distinguish α-PPH and β-PPH applicable scenarios, causing improper material selection. Our technical team offers free customized selection solutions based on medium, temperature and pressure, minimizing long-term operational risks with full construction & after-sales tracking.
4.3 Stable Mass Delivery Capacity
Large industrial projects require bulk supplies under tight schedules. Jiqing operates 18 synchronized production lines with dedicated raw material warehouses and sufficient off-the-shelf inventory, fulfilling large batch orders and guaranteeing on-time project progress.
Frequently Asked Questions for Engineering Material Selection
Q1: Should I choose α-PPH or β-PPH for industrial projects?
A1: Judge by three factors: temperature, medium and service life
α-PPH: Long-term temp ≤80°C, mild corrosion, temporary projects
β-PPH: Operating temp 70–95°C, strong acid/alkali medium, designed service life ≥10 years
Q2: How to identify genuine qualified β-PPH pipes?
A2: 3-step verification
Raw material confirmation: Require virgin material batch certificates without recycled blends
Performance test: Request third-party reports covering oxidation induction time, low-temperature impact strength, heat deflection temperature and tensile strength
Standard & marking check: Confirm compliance with QB/T 5099 and complete laser coding printed on each pipe body

Q3: What core edges does Jiqing have against competitors?
A3:
Annual capacity 15,000 tons, full DN15–DN1200 self-produced piping series with consistent welding compatibility
Triple inspection system passing strict acceptance of high-end industrial projects
Intelligent lines with sufficient spot inventory for steady delivery
Full lifecycle service: material selection, on-site welding instruction and post-operation maintenance
Custom thickened pipes & special fittings for harsh corrosive environments
Q4: Can β-PPH pipes and fittings from different manufacturers be welded together?
A4: Not recommended. Different suppliers use beta crystals of varying content and melt index, resulting in uneven molecular fusion during welding and hidden leakage risks. Unified procurement from one single manufacturer ensures full pipeline safety.
