Service Process
Hengshui Guanlin Fluoroplastic Pipe Co., Ltd. is customer-centric, delivering a seamless, worry-free collaboration experience throughout the entire lifecycle.
Requirement Consultation and Initial Coordination
1. Rapid Response
◦ Customers submit their requests via telephone, the official website, offline trade shows, and other channels; the customer service team will proactively reach out for communication within 24 hours.
◦ Key recording items: medium type (e.g., acids, bases, solvents), application scenario (chemical, pharmaceutical, environmental protection, etc.), specification parameters (pipeline pressure, storage tank volume), and special requirements (non-standard components, hygienic-grade standards, etc.).
2. Technical Pre-assessment
◦ The technical team will conduct an assessment, taking into account factors such as media corrosivity, temperature, and pressure, to make a preliminary evaluation of the suitability of steel-lined PTFE (PTFE/FEP/ETFE) and provide free corrosion-protection solution recommendations.
Scheme Design and Contract Signing
1. Customized Solution Delivery
◦ For standard requirements: provide standardized design drawings (including coating thickness, connection methods, etc.);
◦ For non-standard or complex components and operating conditions: the technical team will deliver a customized solution within 48 hours (e.g., design of non-standard pipe bending angles, anti-delamination lining technology for storage tanks), accompanied by 3D models or CAD drawings for approval.
2. Business Negotiations and Contract Signing
◦ Clearly define the project timeline (7–15 days for standard orders; custom orders subject to negotiation based on complexity), pricing, acceptance criteria, and after-sales terms.
◦ A formal contract will be signed, supporting a prepayment plus final payment upon acceptance model, and a 13% special VAT invoice will be provided.
Production Manufacturing and Process Control
1. Execution of Mass Production
◦ Standardized operations in a 10,000-square-meter workshop:
• Steel surface preparation: blast cleaning to achieve Sa2.5 rust removal grade, ensuring coating adhesion;
• Dual-application construction: Select spray coating (suitable for complex structures) or roll coating (suitable for large, flat surfaces) based on the product type, with coating thickness uniformly controlled at 1.5–3 mm.
• Weld joint treatment: An integral sintering process is employed to eliminate the risk of weld seam leakage.
2. End-to-End Quality Tracking
◦ Quality inspection points are established for each process step: coating thickness inspection (using a magnetic thickness gauge), spark leak detection (with a no-leak criterion), and pressure testing (for pipelines, at ≥1.5 times the working pressure).
◦ Process photos/videos will be provided, and the customer may request on-site supervision.
Acceptance, Delivery, and Installation Guidance
1. Finished Product Acceptance
◦ Acceptance shall be conducted in accordance with the contract specifications, and third-party test reports shall be provided (e.g., corrosion resistance tests, high-temperature aging tests);
◦ Supports on-site acceptance by the customer or third-party testing; non-conforming products shall be reworked unconditionally.
2. Flexible Delivery Solutions
◦ Logistics and Delivery: Partnering with nationwide logistics providers to cover major industrial regions such as the Beijing-Tianjin-Hebei area, the Yangtze River Delta, and the Pearl River Delta, with shipments dispatched within 72 hours.
◦ Installation Support: Provision of installation drawings and remote technical guidance; for complex projects, engineers can be dispatched on-site to provide assistance.
After-Sales Service and Long-Term Cooperation
1. After-sales service system
◦ Warranty Period: 1 year for standard products; extended for customized products as per the agreement.
◦ 2-hour response: immediate telephone or online reply to after-sales inquiries, with a solution provided within 48 hours;
◦ Regular follow-up visits: Conduct quarterly checks on equipment operating conditions and provide maintenance recommendations.
2. Technical Value-Added Services
◦ Free maintenance training for PTFE-lined steel equipment;
◦ Existing customers enjoy priority scheduling and annual anti-corrosion inspection discounts.
