New Process of Internal FBE

The technology of epoxy powder spraying in the pipeline, because of the high voltage electrostatic spraying, the current market is generally adopted by the Venturi pump spraying process, the powder rate has been hovering around 50%, especially the diameter of more than 500 millimeter steel pipe is lower. The powder recovery is large and the overflow powder is serious.

In order to change the current situation and meet the domestic and foreign customers' pursuit of increasing powder rate, Qingdao Dacang Anticorrosion Co., Ltd. has successfully developed a new generation of epoxy powder spraying technology in the pipeline for nearly two years, with a high powder rate of up to 95%.

Technological innovation and technological breakthroughs provide strong support for the new generation of epoxy powder spraying technology in pipelines.

A BRIEF INTRODUCTION TO THE AUTOMATIC ANTICORROSION PRODUCTION LINE

In order to comply with the development of science and technology, improve the production efficiency and quality of the steel pipe anticorrosion production line, reduce the production cost, reduce the number of operators and enhance the safety, our company has developed a full-automatic steel pipe anticorrosion production line.

The automatic steel pipe anticorrosion production line is a revolutionary upgrading, innovation and development of the widely used steel pipe anti-corrosion production line mode.

The automatic production line promotes, improves and consummates the mechanical properties of the traditional production line. On this basis, a new automatic control system (ACSOSAP) for steel pipe anticorrosion production is addedto realize the automatic production of the steel pipe anticorrosion production line.

The automatic control system for steel pipe anticorrosion production (ACSOSAP) consists of industrial control machine (PC), industrial programmable controller (PLC), touch screen (HIM), frequency converter, industrial Ethernet, SCADA configuration software, and modular production line automatic control software. The internal and external rust removal production line, 3PE process production line, internal and external FBE process production line, internal and external spray paint technology production line, bare pipe line, finished product pipe line, semi finished product transfer, pickling passivation, injection standard, on-line inspection are realized.

The automatic control system (ACSOSAP) for steel pipe anticorrosion production is mainly divided into two levels: workshop monitoring layer and field equipment layer.

Workshop monitoring layer realizes the monitoring of workshop level equipment, which includes on-line monitoring of production equipment status, equipment fault alarm and maintenance, production statistics, production scheduling, data analysis and early warning, production information storage and upload. This layer is mainly composed of industrial computer (PC), industrial programmable logic controller (PLC), SCADA configuration software and industrial Ethernet.

The field device layer implements devices that are mainly connected to the on-site production line, such as distributed I/ O, drives, actuators, sensors, intelligent meters, etc. Complete the process control and chain control of the production line, and the operation status of the production line and the collection and uploading of production information. The layer is mainly composed of industrial programmable logic controller (PLC), touch screen (HIM), frequency converter and modularized control software.

AUTO SWITCH CONVEYING EQUIPMENT AT PRODUCTION LINE

When switching pipe according to different diameter of steel pipe in traditional coating production line,it is done by manpower, which wastes time and is concerned with safety. This new patent technology can be automatic opening and closing according to pipe diameter, without manual work. It has the advantages as following:

1. High automatic performance, improving productivity. 

2. Reducing labor intensity, and improving, safety. 

3. The roller wears evenly in long term use, stable conveying, ensuring coating quality.

Intelligent Network

Since 2010, Qingdao Dacang anticorrosion Co., Ltd. has paid great attention to the application of Internet technology in the pipeline, especially in November 2014, which occurred in the Sinopec oil pipeline in Huangdao District of Qingdao City, which caused the heavy casualties and urban damage. We have accelerated the integration of the Internet of things technology with the pipeline protection technology, and gradually developed the intelligent pipeline products and intelligent pipeline and intelligent pipe network technology system of Qingdao Da Cang anticorrosion Co., Ltd., as well as China PetroChina and Sinopec.

Intelligent pipeline

pipeline data self-perception. First, combining intelligent sensor technology with pipeline anticorrosion and insulation technology, a large warehouse intelligent pipe product is developed. That is: the deposited flow sensor and pressure transmitter are planted in the pipeline, and the optical fiber is laid on the outer wall of the pipeline to form an intelligent anticorrosive and heat preservation pipeline. Applied to engineering, it can perceive the vibration and temperature of the body in real time, and the data of pressure and flow of the transmitted fluid.

Smart Pipeline

self-perception, data processing, transmission display and monitoring of the entire pipeline data. The intelligent pipeline is developed with the combination of Internet of logistics, mobile communication technology and computer data processing system.

Comprehensive monitoring and control system platform for pipe network 

The intelligent pipeline is further integrated with GIS geographic information technology and big data technology, and the platform of intelligent monitoring and control system for Qingdao Dacang is generated. The distributed optical fiber sensing technology, the attached flow sensor and the pressure transmitter are formed as the core, the Internet data transmission, the GIS network geographic information digital graphics database, the GPS position technology as the data layer, the integrated server as the data processing center, can be immediately and accurately Whether the pipe network pipeline work is normal or not, the leakage of pipeline pipeline and its location alarm display, the deformation and settlement of pipeline, corrosion protection layer of pipe network, tube corrosion and external damage, plough and excavation damage are early warning.

The function and purpose of intelligent pipe network

The intelligent monitoring and control system for smart pipes and intelligent pipelines is suitable for transporting various fluids. Such as urban water supply network, heating network, gas pipeline network, various kinds of oil and gas pipelines, chemical process network, etc.

With the development of Dacang, we will pay more in pipeline engineering and research better construction techniques, construction equipment and new pipeline connection schemes. It is believed that "Dacang for Pipeline engineering" will soon become a familiar voice.
