What s the deal with pipeline inspection? 50

Pipeline inspection company to find leak point technologyThe main service objects are: large and small properties, factories, hotels, families, etc.

A professional water pipeline inspection company, the first organization to eliminate potential dangers. Leakage Point Technology Pipeline Testing Company, good technology, strong professionalism and trustworthy.

Pipeline detection is through traditional means to detect or use Jiaxing Dagong's pipeline robot intelligent detection of pipelines, the traditional detection means are relatively single, the detection effect is not as good as Jiaxing Dagong pipeline robot, mainly used for pipeline internal precision detection, can achieve trenchless cutting operations, with sonar equipment, only a simple operation can achieve intelligent pipeline detection.

Pipeline detection has traditional pipeline detection methods and Ningbo Guangqiang's intelligent pipeline robot detection methods, our country has been using traditional pipeline detection before, the detection method is limited can not meet the detection needs of modern pipeline development, the results of the detection are not detailed and clear of Ningbo Guangqiang pipeline robot, pipeline detection is mainly through closed-circuit television detection and sonar equipment intelligent detection does not require soil covering excavation operations, simple operation process can easily detect pipelines.

The main purpose of the inspection of buried pipelines in use is to evaluate the structural integrity of the pipeline body, and the detection content includes four aspects: position direction survey, corrosion evaluation, leakage detection and defect detection technology. According to its characteristics, the detection technology can be divided into two categories: internal detection and external detection. The internal detection technology mainly uses pipeline robots to carry out testing devices.

According to whether it is necessary to be in direct contact with the pipe body, the external detection technology is divided into excavation detection and trenchless detection technology.

Installation needs to be welded, welding needs to do flaw detection, there is no air leakage, or the materials and construction plans used are not qualified according to the standards of the drawings before they can be accepted.

Pipeline CCTV (Closed Circuit Television) detection is the use of advanced CCTV pipeline endoscopic television detection system, which automatically crawls in the pipeline to detect and camera the rust layer, scaling, corrosion, perforation, cracks and other conditions in the pipeline, and then evaluates it according to the detection technical regulations, providing an important basis for formulating repair plans. Zhongyi IOT Technology Co., Ltd. independently developed a new type of pipeline testing equipment, which can detect pipelines with different diameters and different situations.

Find me!! I'll send you a tutorial.

China Petroleum Pipeline Testing Technology Co., Ltd.

It was registered and established in Langfang Administration for Industry and Commerce on February 20, 2006. Cao Chongzhen, the legal representative, the company's business scope includes pipeline intelligent detection, pipeline anti-corrosion layer detection, storage tank detection, underground pipe network cable direction and buried depth detection, etc.

Pipeline inspection technology

The main purpose of testing buried pipelines in use is to evaluate the structural integrity of the pipe body, and the detection content includes four aspects: location and trend investigation, corrosion evaluation, leakage detection and defect detection technology.

According to its characteristics, the detection technology can be divided into two categories: internal inspection and external inspection. The internal detection technology mainly uses assembly line robots to carry detection devices for testing.

According to whether direct contact with the pipe body is required, external detection technology is divided into excavation detection and trenchless detection technology.

Hello dear. There are many pipeline inspection companies in China, and the following are the profiles of some representative companies:1

CNPC Pipeline Testing Co., Ltd.: The company is a professional pipeline inspection company under China National Petroleum Corporation, and its business scope includes oil, natural gas, petrochemical, chemical and other industries. 2.

Sinopec Pipeline Technology Co., Ltd.: The company is a high-tech company under Sinopec, whose business covers pipeline inspection, construction, maintenance and other aspects. 3.

China Petroleum Pipeline Project: The company is a state-owned enterprise under China National Petroleum Corporation, and its business scope includes oil and gas pipelines, city gas pipelines, etc. 4.

Shandong Gonghe (Group)****: The company is one of the earliest enterprises to carry out pipeline testing in China, with a number of patented technologies, mainly serving the oil, gas and other industries. 5.

Nanjing Ruilin Instrument Technology Co., Ltd.: The company is a high-tech enterprise focusing on the research and development, production and sales of flowmeters and other instrument products, and also provides pipeline testing services.

Summary. Except for pipelines that transport non-toxic, non-flammable and non-corrosive gases with a nominal diameter of less than 150mm and whose maximum working pressure is less than the gauge pressure, and the pipelines to which the equipment body belongs.

Dear, the pressure pipeline needs to be supervised.

Supervised inspection is required for the process of replacing pipes with a total length of more than 100 meters for the same medium at one time. Note: Major repair of pressure pipelines, rotten burial refers to the use of welding methods to replace pipe sections, valves, pipe orthopedics, welding repair of missing parts of the chain under pressure, sealing under pressure and plugging under pressure.

Shed Calendar Debate. The nominal diameter is less than 150mm, and the highest working pressure is less than the gauge pressure) except for the pipeline that transports non-toxic, non-flammable and non-corrosive gases and the pipeline to which the equipment body belongs.

The pipeline is used to transport, divide the chain distribution, mixing, separation, discharge, measurement, control and stop the flow of fluids, and is composed of pipes, pipe fittings, flanges, bolt connections, gaskets, valves, other components or pressure parts and supporting parts.

Thank you. You're welcome, dear.

How much do you know about pipeline inspection methods?

Dear, [old and clever] glad to answer for you! Pipeline inspection method: 1:

Electromagnetic induction method: It is an efficient method for detecting metal pipelines and pipelines with metal skeletons, and can also be used to detect non-metallic pipes with entrances and exits. 2：

Electromagnetic wave method: It is mainly used to detect the non-metallic potato cleaning pipeline and the pipeline and difficult points in the more complex sections. 3：

Mechanical method: It is mainly used to verify the precision and accuracy of other methods. The detection of underground pipelines should follow the standards of first known and then unknown, from simple to more complex, and give priority to efficient, fast and lightweight detection methods, and comprehensive methods should be adopted under complex conditions.

Before the detection, according to the characteristics of the geoelectric situation, road section environment, pipeline distribution and other characteristics of the survey area, the known pipelines of representative road sections were selected for testing. Hope mine can help you! <>
