The PCCP products manufactured by Hanjian Heshan implement strict quality control from the time the raw materials enter the factory. Products in the intermediate process can only enter the next production process after passing the "three inspections", and the final products can only be shipped after passing the type inspection and the factory inspection. , To meet the requirements of national standards, specifications and the major engineering contract standards involved.
Project:Prestressed concrete cylinder pipe
Declaring enterprise:Beijing Hanjian Heshan Pipeline Co., Ltd.
Reason of Recommendation
1. Development towards intelligence and cloud data on PCCP production equipment. Developed the robot welding for the butt joint of the socket and the steel ring, the intelligent equipment for the spiral welded steel cylinder to be ejected and transported out, the whole process of spraying and quality automatic control system of the cement paste for wire wrapping and spraying, and the application of the PCCP production quality management system (RFID technology).
2. In terms of process reform and innovation, it has successfully realized that the molding production line adopts the nested hoisting process of large and small gantry cranes. The processes are carried out synchronously without interfering with each other, which effectively improves the production efficiency.
3. In the fields of super-large diameter PCCP pipes design, structural safety, quality control, professional equipment and application, it has carried out extensively and in-depth technical exchanges and research. it successively solved a number of major technical problems of socket, socket sealing, concrete durability, cathodic protection, armored joints, and types Tests, external anti-corrosion materials and technology, research on steel wire anchoring and stress stability control, RFID technology, wire wrapping, full-process injection of cement paste for shotcreting and automatic quality control systems, etc. It has developed unpowered pipe turning machine, compensation balance wire winding machine, pre-winding wire stress stability control system, self-loading and unloading PCCP special pipe transporter, welding with a robot that connects with spreaders, sockets, and socket steel rings, Intelligent equipment for spiral welded steel cylinders to be pulled out, transported out and turned over, and formed 90 patented technologies.
