Performance for Irrigation Systems
Designed for continuous working pressures from 0.6 MPa to 1.6 MPa, with suitable pressure classes available for different irrigation systems.
Resistant to many agricultural fertilizers and soil chemicals, helping reduce corrosion, scaling, and material degradation during long-term use.
Smooth internal walls help reduce friction loss and support efficient water flow, particularly in longer irrigation pipelines.
Carbon black additives at ≥2.5% provide UV protection for irrigation pipes exposed to outdoor sunlight.
High impact resistance and flexibility allow the pipe to accommodate moderate ground movement and installation conditions with reduced risk of cracking.
Irrigation Applications
Sprinkler Irrigation: Delivering high-pressure water reliably to center-pivot and overhead sprinkler networks.
Drip Irrigation: Providing robust main and sub-main distribution lines for precision micro-irrigation and fertigation farming.
Greenhouse Water Supply: Durable, chemical-resistant routing for climate-controlled agricultural and hydroponic environments.
Farm Water Distribution: Large-diameter trunk lines (DN315 to DN1200) optimized for bulk water transfer between reservoirs, rivers, and fields.
Selecting the Right Pipe
Flow Rate Requirements: Determining the optimal internal diameter based on peak water volume demands at the field discharge point.
Operating Pressure & SDR: Selecting the correct Standard Dimension Ratio (SDR) - such as SDR 11, SDR 13.6, SDR 17, or SDR 21 - to safely match your system pump output and working head.
Environmental Factors: Assessing trench soil conditions, burial depth, and ambient surface temperatures to specify the appropriate wall thickness and safety factors.
Manufacturing & Quality Control
Sourced exclusively from tier-1 petrochemical suppliers, incoming virgin PE100 resins undergo laboratory testing for density, melt flow index (MFI), and oxidative induction time (OIT).
Advanced automated extrusion lines help maintain uniform wall thickness and roundness during continuous production.
Real-time laser-guided measurement systems monitor outer diameter (OD) and ovality tolerances across production batches.
Random samples from production runs undergo routine testing, including hydrostatic pressure testing, tensile strength analysis, and longitudinal reversion checks, following standard industrial practices.
Field Installation & Fusion Guidelines
Butt Fusion Parameters (PE100)
Heating Temp: Maintained strictly at 200°C – 220°C.
Cooling Pressure: Kept at 0.15 – 0.20 MPa interface pressure until joints cool below 40°C.
Bead Formation: Requires a uniform, symmetric melt bead around the entire pipe circumference.
Electrofusion Support
Compatible with automated barcode-scanning fusion units for precise energy input in confined trenches.
Trenching & Bedding
Recommend fine granular bedding (particle size < 10mm) free of sharp rocks, with side-fill compacted to 90% Proctor density.
Supply & Matching Fittings
Complete System Integration: We supply a full suite of compatible butt fusion and electrofusion fittings to ensure uniform system integrity, including:
Fittings: Elbows, Tees, Reducers, Equal/Reducing Tees, and End Caps.
Flanged Adaptors & Stub Ends.
Customization: We support project-specific customization, including bespoke color-coding stripes (blue lines for water), custom length cutting, and laser-printed project IDs or company branding.
Scalable Logistics: Whether equipping a family-owned farm or fulfilling a regional government infrastructure contract, we provide efficient batch shipping, container optimization, and project-based delivery scheduling.
Frequently Asked Questions
Q: Can these pipes be used in sub-zero temperatures?
A: Yes, PE100 HDPE pipes maintain high ductility in low temperatures, making them ideal for diverse climates.
Q: How are connections made in the field?
A: We recommend butt fusion or electrofusion welding to create a monolithic, leak-proof joint.
Q: Do you support third-party pre-shipment inspections (e.g., SGS, BV)?
A: Yes. We fully cooperate with independent inspectors (SGS, BV, Intertek, TÜV) and provide MTC with every shipment.
Q: What standards do your pipes comply with?
A: Manufactured in strict compliance with international standards including ISO 4427, EN 12201, and ASTM D3035.
Q: What is the lead time for large bulk orders?
A: Lead time depends on volume and diameter. Please share your project specifications for an accurate delivery timeline.
Q: Do you provide on-site welding equipment or installation guidance?
A: Yes, we supply fusion machines upon request and provide digital manuals, video guides, and remote technical support.
Q: What is the minimum order quantity (MOQ)?
A: MOQ varies by diameter and customization. Please share your project volume for confirmation.
Q: What packaging and shipping methods are used?
A: Coils are strapped on pallets, while straight pipes (6m/12m) are nested in 20GP or 40HQ containers for optimal space efficiency.
