What is Jianlong's production capacity and R&D strength? Can you handle concentrated supply for large infrastructure projects?

2025-12-16
We operate a modern production base with an annual capacity exceeding 100,000 tons. Equipped with PE pipe production lines, PVC-U extrusion lines, and fully automatic injection molding machine clusters, we ensure the stability and consistency of supply for large-scale projects.

Our R&D center houses a material testing laboratory (capable of Melt Flow Index, Slow Crack Growth tests, etc.) and a pilot production line. We have supplied over 5,000 kilometers of HDPE pipes for multiple national-level municipal pipeline networks and transnational industrial parks. We establish dedicated project green channels and implement a "one-on-one" project manager responsibility system, tracking the entire process from production scheduling, quality inspection to logistics, ensuring on-time delivery.

Related questions
1
Can you provide OEM production for HDPE pipes and PVC fittings for municipal projects or building material distributors?
With over 30 years of experience in plastic pipe OEM/ODM services, we offer comprehensive white-label solutions for municipal contractors and building material chains. Specific services include: producing HDPE double-wall corrugated pipes to custom diameters based on your engineering standards; embossing your brand logo on PVC-U drainage pipe surfaces; adjusting the antibacterial formulation of PP-R pipes according to regional water quality; even developing exclusive colors of PE-RT heating pipes for your HVAC company.

All OEM plastic pipes use raw materials of the same grade as our "Jianlong" brand products, sharing the ISO9001 Quality Management System and annual SGS factory audit supervision. Please submit your technical parameter sheet for MPP power pipes or PE irrigation pipes, and we will provide a sampling plan within one week.
2
What packaging standards are used for exporting HDPE pipes and PVC fittings? Can eco-friendly packaging be customized?
Our plastic pipe export packaging strictly follows ISTA international transport standards. HDPE double-wall corrugated pipes are bundled with steel straps and UV-resistant stretch film, with high-strength plastic end caps. PVC-U drainage pipes and PP-R pipes are packed in custom cartons or on wooden pallets with inner waterproof PE liners. Small-diameter PE irrigation pipes can be coil-packed and covered with shrink film.

All packaging is marked with the product name (e.g., HDPE Water Pipe), ISO9001 certification logo, and international symbols like "Keep Dry." Responding to environmental needs, we offer biodegradable stretch film and FSC-certified recycled wood pallets for PE pipe transport. If you require your company logo printed directly on PVC fitting bags, we support customization and can provide packaging material tests certified by SGS.
3
What are the lead times for HDPE water pipes, PVC-U fittings, and PE-RT underfloor heating pipes?
As a one-stop plastic pipe supplier, lead times vary by product type and order size. Standard specifications of HDPE water pipes (DN20-DN500) are typically available from regular stock within 7-10 days, while batch production requires 25-35 days. The mold-based production cycle for PVC-U drainage pipes and fittings is 30-45 days.

PE-RT underfloor heating pipes (with oxygen barrier) require dedicated production lines, with a lead time of approximately 40-50 days. For initial orders of MPP power pipes or custom-sized HDPE double-wall corrugated pipes, involving raw material procurement and process setup, we recommend allowing 60 days. During peak seasons (e.g., concentrated municipal project procurement), lead times may extend by 10-15%.
4
If quality problems occur with purchased HDPE double-wall corrugated pipes or PVC-U drainage pipes, how are they handled?
For HDPE double-wall corrugated pipes used in municipal drainage projects or PVC-U drainage pipes used in construction, we implement a full lifecycle quality commitment. Once a defect is confirmed to originate from our production process (e.g., uneven wall thickness, incomplete fusion line), we activate an emergency protocol. This involves quarantining and tracing the problematic batch of PE pipes.

Simultaneously, based on your project schedule, we prioritize replacement production or allocate stock from nearby warehouses (for standard products like HDPE water pipes and PE-RT heating pipes). For already installed PVC fittings, we provide on-site technical repair guidance. We will compensate for direct losses caused by confirmed plastic pipe quality issues according to the purchase contract and third-party assessment. A root cause analysis report will be submitted to you to ensure similar issues do not recur in other product lines like PP-R pipes or MPP cable conduits.
5
How to obtain samples of HDPE pipes, PVC-U fittings, or PP-R pipes?
As a professional plastic pipe manufacturer, we encourage clients to verify product quality and suitability through samples. You can test the ring stiffness of our HDPE pipes, the corrosion resistance of our PVC-U pipes, and the heat fusion performance of our PP-R pipes. Samples are provided free of charge, offering a tangible evaluation opportunity for PE pipes, PVC fittings, or PE-RT heating pipes.

The client is responsible for international shipping costs from our factory to the destination. If you place a formal order after testing samples of MPP power pipes or PE irrigation pipes, we can deduct this freight cost from your first order. Please contact us via the official website email or WhatsApp, specifying the plastic pipe model, specifications (e.g., DN110 HDPE double-wall corrugated pipe), and intended use. We will then arrange shipment.
6
Besides traditional products, what innovations does your company have in new smart or eco-friendly pipes?
We continuously pursue product innovation:
1. Smart Pipes: Developing HDPE water supply pipes integrated with leakage monitoring optical fibers for real-time perception of pipeline network status.
2. Eco-friendly Products: Introducing high-impact resistant and quiet PVC-U drainage pipes (10 dB noise reduction compared to standard pipes) and PE protection pipes made from biodegradable materials (for temporary works).
3. System Solutions: Providing prefabricated pumping stations (with HDPE tanks) and sponge city infiltration drainage systems (using HDPE perforated drainage pipes). All innovative products are detailed in the "Product Center" on our official website. You can also directly contact our Innovation Division for the latest technical whitepapers.
