Service Process

Hengshui Guanlin Fluoroplastic Piping Co., Ltd. Service Process Description

Customer-oriented approach, creating a worry-free full-cycle cooperation experience

I. Demand Consultation and Initial Engagement

1. Quick Response

◦ Customers submit requests via phone, official website, offline exhibitions, and other channels; customer service team actively contacts within 24 hours;

◦ Key records: medium type (e.g., acid-base, solvent), application scenario (chemical/pharmaceutical/environmental protection, etc.), specifications (pipe pressure/tank volume), special requirements (custom-shaped parts, sanitary standards, etc.).

2. Technical Pre-assessment

◦ The technical team intervenes, combines working conditions such as medium corrosiveness, temperature, and pressure, preliminarily assesses the applicability of steel-lined fluoroplastics (PTFE/FEP/ETFE), and provides free anti-corrosion solution suggestions.

II. Solution Design and Contract Signing

1. Customized Solution Output

◦ For conventional requirements: Provide standardized design drawings (including coating thickness, connection methods, etc.);

◦ For custom-shaped parts/complex working conditions: The technical team will issue a personalized solution within 48 hours (e.g., non-standard pipe bending angle design, anti-peeling process for tank linings), accompanied by 3D models or CAD drawings for confirmation.

2. Business Negotiation and Signing

◦ Clarify lead time (7-15 days for standard orders, customized orders negotiated based on complexity), price, acceptance standards, and after-sales terms;

◦ Sign a formal contract, support deposit + final payment upon acceptance model, and provide a 13% special VAT invoice.

III. Production Manufacturing and Process Control

1. Large-scale Production Execution

◦ 10,000 square meter workshop standardized operations:
• Steel pretreatment: Sandblasting and derusting to Sa2.5 grade to ensure coating adhesion;
• Dual process construction: Select spraying (suitable for complex structures) or roller coating (suitable for large flat surfaces) according to product type, with uniform coating thickness controlled at 1.5-3mm;
• Weld joint treatment: Adopting integral sintering process to avoid weld seam leakage risk.

2. Full Process Quality Tracking

◦ Quality inspection points set for each process: Coating thickness detection (magnetic thickness gauge), spark leak detection (no leakage point standard), pressure test (pipes ≥1.5 times working pressure);

◦ Provide process photos/videos; customers can request on-site supervision.

IV. Acceptance Delivery and Installation Guidance

1. Product Acceptance

◦ Acceptance according to contract standards, providing third-party test reports (e.g., corrosion resistance test, high-temperature aging test);

◦ Support customer on-site acceptance or entrust third-party inspection; unqualified products will be reworked unconditionally.

2. Flexible Delivery Solutions

◦ Logistics distribution: Cooperate with nationwide logistics, covering major industrial zones such as Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta, and dispatch within 72 hours;

◦ Installation support: Provide installation drawings and remote guidance from technical personnel; for complex projects, engineers can be dispatched for on-site assistance.

V. After-sales Service and Long-term Cooperation

1. After-sales Guarantee System

◦ Warranty period: 1 year for standard products, extended for customized products as per agreement;

◦ 2-hour response: Immediate phone/online reply for after-sales issues, solution provided within 48 hours;

◦ Regular follow-up: Quarterly tracking of equipment operation status, providing maintenance suggestions.

2. Value-added Technical Services

◦ Free provision of maintenance training for steel-lined fluoroplastic equipment;

◦ Regular customers enjoy priority scheduling and annual anti-corrosion inspection discounts.
