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.

Question 2

What packaging standards are used for exporting HDPE pipes and PVC fittings? Can eco-friendly packaging be customized?

Accepted Answer

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.

Question 3

What are the lead times for HDPE water pipes, PVC-U fittings, and PE-RT underfloor heating pipes?

Accepted Answer

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%.

Question 4

If quality problems occur with purchased HDPE double-wall corrugated pipes or PVC-U drainage pipes, how are they handled?

Accepted Answer

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.

Question 5

How to obtain samples of HDPE pipes, PVC-U fittings, or PP-R pipes?

Accepted Answer

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.

Question 6

Question 9

For exporting plastic pipes, what are the common packaging methods and container loading plans?

Accepted Answer

For plastic pipe exports, we employ professional packaging: HDPE double-wall corrugated pipes (max 6m length) are bundled with steel straps and entirely wrapped in waterproof film. A 40ft HQ container can hold approximately 26-28 cubic meters. PVC-U solid-wall pipes are packed in custom carton sets with internal shock-absorbing corner pads.

Small-diameter PP-R pipes (4m fixed length) are packed on pallets with shrink film. A 20ft container can hold about 1200 pieces. We provide detailed container loading calculation sheets and on-site loading photos to ensure maximum loading efficiency and transport safety.
Furthermore, we can print project information, barcodes on the packaging, or use recyclable eco-friendly materials per client request, and provide fumigation certificates and certificates of origin meeting destination port requirements.

Question 10

Can Jianlong provide custom processing services for non-standard plastic pipe fittings?

Accepted Answer

We possess strong capabilities for custom plastic fittings manufacturing. Clients can provide CAD drawings or samples, and we utilize CNC machining centers and large injection molding machines for production. Customization ranges include: HDPE flange elbows with special angles, reducing PVC-U drainage tees, MPP power pipe couplings with tracer wire channels, and PP-R pipe decorative sleeves printed with client logos.

For large-diameter HDPE profile wall pipes (DN1200 and above), we can prefabricate "U"-shaped sections at the factory, significantly reducing on-site welding. The customization process is: technical evaluation → mold design (cycle 15-30 days) → sample confirmation → mass production. All custom fittings enjoy the same quality guarantee as our standard products.

Question 11

What are the construction specifications for laying PE-RT underfloor heating pipes? How to prevent oxygen permeation and local overheating?

Accepted Answer

PE-RT underfloor heating pipe installation must follow strict specifications:

1. Design Phase: Use professional software for heat load calculation. Pipe spacing should be 150-300mm, single loop length ≤120m, and resistance imbalance <15%.

2. Material Selection: It is essential to choose five-layer co-extruded PE-RT pipes with an oxygen barrier layer to prevent oxygen diffusion from corroding metal components in the system.
3. Laying Process: The pipe bending radius must be ≥6 times the pipe diameter, secured with plastic clips. Kinks are strictly prohibited.

4. Pressure Testing: Conduct separate pressure holding tests at 0.8MPa (pressure drop ≤0.05MPa in 24 hours) after laying and before concrete pouring. 5. System Protection: Set temperature limits (supply water temperature ≤60°C). We provide complete technical briefings and on-site supervision services.

Question 12

When designing an agricultural irrigation system, how to choose suitable PE irrigation pipes and drip tape products?

Accepted Answer

When designing agricultural irrigation systems, selection is based on the following: For main water transmission lines from the source to the fields, we recommend using PN1.0MPa rated HDPE water supply pipes (DN90-DN250), which are weather and UV resistant, suitable for burial or above-ground laying. Field laterals can use LDPE layflat hose or PVC-U agricultural pipes.

The core of the drip irrigation system is the inline drip tape. We offer various thicknesses from 0.2mm to 0.6mm, with emitter flow rates from 1.0 to 3.0 L/h, featuring a labyrinth channel design for clog resistance. Jianlong can provide complete system design and installation guidance, from water source filtration and fertilizer tanks to the PE pipe network and drip tape, helping achieve integrated water and fertilizer management with water-saving efficiency of 40%-60%.
