AI-Powered supplier vetting

SummaryZhejiang Fengfeng Pipe Industry Co., Ltd. is a China-based limited company established in 2002, with 77 employees and products focused on HDPE, electrofusion, and buttfusion pipe fittings. It reports customization from samples, annual HDPE pipe fitting output of 1,000,000 pieces, and peak- and off-season lead times within 15 workdays. The supplier exports to Southeast Asia and the Middle East, with exports representing 31%–40% of total sales, and has participated in WORLDBEX. Its documented management evidence includes ISO 9001:2015 certification, an environmental impact assessment report, and recent fire drills. However, it reports no SDK, overseas warehouse, showroom, agent or branch capability. Service procedures, complaint handling, corrective actions, and finished-product inspection procedures exist but lack written records. The provided audit record identifies SGS, but the evaluation result is recorded as 0 and the report has expired.

Supplier typeThe supplier is a China-based limited company with 77 employees, established in 2002, and no stated affiliation with a larger company group. Its product scope is specialized in HDPE pipe fittings, electrofusion fittings, and buttfusion fittings.

CertificationsThe supplier reports an ISO 9001:2015 certificate, an environmental impact assessment report, and regular fire drills during the past year. However, the SGS report shown in the information expired on 2025-04-26, and its evaluation result is recorded as 0, so current external audit standing is not clearly favorable.

R&D capabilityThe supplier explicitly reports no available SDK, which is a stated deficiency for SDK-based development capability. It does report customization from samples, but this supports adaptation capability rather than broader innovation or R&D strength.

Production capacityThe supplier reports annual HDPE pipe fitting output of 1,000,000 pieces and lead times within 15 workdays in both peak and off-season. Its products, export markets, port access, and export methods are specified, but the stated inspection method has instructions without written records, indicating a documentation weakness rather than a proven production failure.

Customization capabilityThe supplier explicitly offers customization from samples, demonstrating a stated ability to develop customized products based on customer-provided samples. No additional evidence is provided regarding engineering resources, tooling scope, or design documentation.

Product Q&A

Q:Why choose us?

Factory Direct Pricing, Large Stock, Quality. Manufacturer offers fittings from 20mm to 1400mm, rated for PN10 to PN25. Custom branding and products are backed by three plants. We maintain large inventory, offer competitive pricing with strict in-house quality control, and rapidly source and consolidate all related piping products.

Q:What is common Uses of HDPE/PE/PPR/PERT II pipe & fittings?

Commonly used in construction materials, household products, and agricultural applications. Applications include urban and rural drinking water projects, sewage and wastewater systems, drainage and storm-water management, underground firewater pipelines, infrastructure projects, airports, ports, railways, highway drainage, sports venues, landscape irrigation, geothermal heating/cooling, solar/wind farm water piping, municipal water distribution, agricultural irrigation, gas distribution networks

Q:What is the key Benefits of Electrofusion Fitting?

Achieves a zero-leakage, permanent joint through a molecular bond between fitting and pipe. The process involves thermal fusion where polymer chains interdiffuse and recrystallize into a single mass. Smart technology uses barcodes to store welding parameters, ensuring automatic process control, real-time monitoring, and data logging for traceability. Unlike mechanical fittings, it has no seal aging or vibration sensitivity, offering lifetime performance equal to the pipe (50+ years).

Q:What is the Step of Process Purpose & Anti-Leak Mechanism?

Step 1: Surface Preparation to remove oxidized layers. Step 2: Clamping & Alignment to eliminate stress. Step 3: Initiation & Heating to create a uniform melt zone. Step 4: Melting & Interfusion where molten materials merge and fusion beads fill gaps. Step 5: Controlled Cooling to prevent stress cracks. This ensures a stress-free joint that maintains integrity under cyclic pressure and temperature changes.

Q:What is HDPE?

High-Density Polyethylene is a thermoplastic polymer known for high strength-to-density ratio, durability, and impact resistance. We use brand-new, virgin HDPE raw materials from traceable sources (e.g., SHANGHAI JINFEI, ZHEJIANG PETROLEUM). This guarantees Core Performance (PE100/PE100RC classification), Environmental Stress Crack Resistance (ESCR), Consistent Electrofusion Quality, and Dimensional Stability. It ensures a 50+ year service life, passes international certifications (CE, ISO), and
