Empowering Carbon Industry Upgrades: Dezhou Huafeng Machinery Supports Jinan Wanrui Carbon in Advancing the New Construction and Dismantling Project of Nine 85 m³ Bitumen Storage Tanks
The Bitumen Storage Tank Construction and Dismantling Project undertaken by Dezhou Huafeng Machinery Equipment Manufacturing Co., Ltd. for Jinan Wanrui Carbon Co., Ltd. has reached a key stage of implementation.
As a professional manufacturer with extensive experience in bitumen melting, storage, and heat-exchange equipment, Huafeng Machinery is leveraging its strong technical expertise and customized manufacturing capabilities to provide Jinan Wanrui Carbon with an efficient, environmentally friendly, and intelligent bitumen storage and conveying system. The project is designed to provide solid technical support for the stable operation and green transformation of Jinan Wanrui Carbon’s carbon production line.
Advanced Engineering: High-Standard Horizontal Bitumen Storage Tank System
As part of this project, Huafeng Machinery designed and manufactured nine horizontal bitumen storage tanks, each with a capacity of 85 m³, for Jinan Wanrui Carbon.
The main tank body adopts a horizontal structure measuring approximately φ3,800 × 7,500 mm, providing an effective balance between space utilization and structural stability.
To maintain the proper flowability of bitumen and achieve precise temperature control during storage and conveying, Huafeng Machinery integrated an efficient internal heating tube system into each storage tank.
Heat Transfer Area and High-Performance Tubes
Each storage tank is equipped with a heating tube bundle with a total heat-transfer area of approximately 45 m². The heating tubes are manufactured using φ51 × 3 mm boiler-grade tubes, ensuring efficient and uniform heat transfer while providing durability and reliable long-term operation.
High-Performance Insulation and Protection
Each tank is equipped with a 100 mm-thick fiber blanket insulation layer and an external 0.5 mm-thick color-coated steel sheet. This structure effectively reduces heat loss, improves thermal efficiency, and helps maintain stable bitumen temperatures while reducing energy consumption.
Precise Monitoring System
Each storage tank is equipped with a pressure-type level gauge and dedicated bitumen temperature measurement points, enabling real-time monitoring of the material level and temperature inside the tank and providing operators with accurate operating data.
Process Optimization: Building an Efficient, Closed-Loop and Automated Conveying Network
In terms of overall process design, Huafeng Machinery integrated the newly constructed storage tank area with Jinan Wanrui Carbon’s existing production line to achieve seamless process connectivity.
Controlled Unloading and Settling
After the bitumen tanker trucks arrive at the facility, the bitumen is transferred through the existing unloading pumps and controllably distributed to the nine 85 m³ storage tanks. After an appropriate settling period, the bitumen is conveyed through the outlet piping system into the subsequent production process, providing a stable and continuous supply of raw material.
Integrated Piping and Heat-Tracing System
The bitumen piping and heat-transfer oil piping are connected at suitable locations and routed into the storage tank area. Branch pipelines then connect the main piping network to each individual storage tank. Dedicated heat-tracing systems are installed for the bitumen valves and pipelines, helping maintain the required operating temperature and significantly reducing the risk of bitumen solidification and pipeline blockage.
Environmentally Responsible Fume Treatment
To address bitumen fumes generated during storage, the project routes the bitumen vapors from the storage tanks through dedicated pipelines into the company’s existing centralized treatment system. Centralized collection and treatment approach helps reduce uncontrolled emissions and supports the high environmental standards increasingly required by modern carbon production enterprises.
Intelligent Electrical Control Integration
The supporting electrical control system enables centralized operation and monitoring of the motorized valves, including the inlet and outlet valves of the storage tanks. The system provides valve opening and closing control, status signal transmission and display, as well as centralized monitoring of tank liquid levels and bitumen temperatures. Through these functions, the project significantly improves operational safety, equipment management efficiency, and the level of digitalized process control.
Win-Win Cooperation: Putting “Quality First” into Practice
Dezhou Huafeng Machinery has long been committed to the research, development, design, and manufacturing of equipment for industries including carbon products such as prebaked anodes and graphite electrodes, modified road bitumen, and waterproofing materials.
The successful cooperation with Jinan Wanrui Carbon demonstrates Huafeng Machinery’s engineering capabilities in large-scale bitumen storage, heating, heat preservation, conveying, and supporting control systems. It also represents a practical example of equipment renewal and system upgrading in the carbon industry.
Looking ahead, Huafeng Machinery will continue to uphold its commitment to “Quality First, Service Above All”, providing customized technical solutions, reliable equipment, and professional engineering services. By continuously improving manufacturing quality and system integration capabilities, Huafeng Machinery aims to help industrial customers achieve cost reduction, efficiency improvement, energy conservation, and sustainable green development.
