pipeline crawler information
With the development of the national economy, long-distance fluid transported and gas pipeline play an stronger role in production various fields because of the security and continuity of economic.
The quality of the pipeline will have effect on the life-span and safety of pipelines directly, so the quality of the weld pipe test is particularly important.
In the pipeline weld inspection field, the traditional method is to use X-ray radiation directed with double walls penetrated ,but it needs many times to penetrate the pipeline and get the films, costs too much time and being in heavy workload ,so give bad effect for the progress of the progress. The quality of the penetration and sensitivity is not very good, because of the limited tether of the pipeline.
X-PCD2000 pipe-crawling is the successful invented and the world's advanced level of long-distance pipeline weld quality testing equipment in our company.
It chooses the import-Siemens S7-200 PLC (PLC) as control center, with a strong anti-interference capability, high degree of integration, high-capacity memory and simple programmer, Creeper can be under the full range of Protection. There is a wide range of protective measures, failure is viewed very easily using the screen, the high-precision controller of voltage regulator allows users to set the parameters ,being no change because of the non-energy batteries .
The simple crawler can not control the tube electric current, so reduce the quality of the film due to the decline power of the battery. The design the crawler can control the constant current is the outstanding feature of our crawler which make the device maximize the effectiveness of the efficacy.
Using the Siemens TD200 screen to display and set parameters, the simple operation is the biggest merit of the crawler; the security operation can protect the person safety, because the crawler position system adopts the more popular method of the magnetic orientation to reduce the radiation hazards to people.
The tow models designed is fit for the all kinds of diameter of the pipeline, what is more, there is a good service team in our company in order to supply the comprehensive technology.
