1.Development and Use Horizontal directional drilling technology first appeared in the 1970s as a combination of traditional road perforation and oilfield directional drilling technology, which has become a popular construction method for transporting oil, natural gas, petrochemical products, water, sewage and other materials and for construction of various types of pipelines for electric power and...Read More

With the rapid development of China’s urbanization level, many cities have formed a large scale and intricate underground pipe network tracer line system, frequent changes of underground pipe network, a large amount of information needs to be managed and processed, the traditional inefficient manual management method is difficult to adapt to the needs of this...Read More

Detection background Detection address: a gas pipeline inspection company in HaikouDetection instrument: vLP3 (vLoc3-Pro) pipeline detector, DM3 (vLoc3-DM) anti-corrosion layer detector Detection process The first test point City gas pipeline, according to the requirements need to detect the gas pipeline direction and corrosion-resistant layer breakage point to find. Transmitter red line connected to the target...Read More

1. Undergrounding wire structure: Undergrounding wire attached to plastic. Since the microwave physical ground penetrating radar cannot detect plastic pipes. Tracer wire will cause obstacles to future repairs and other constructions. Therefore, when laying, attach a metal wire to the plastic pipe. It can provide response signs for subsequent maintenance and construction. 2. Tracer wire...Read More

Urban underground plastic pipes play an important role in every modern city. It is the infrastructure on which the city depends for its survival and development. plastic pipes low temperature resistanceGood toughness, rigid and flexibleConvenient constructionlower cost than copper pipesCorrosion resistance, andSmall pollution to the transported material However, although plastic pipes have many of the...Read More

Abstract: The copper conductor tracer wire has limitations in terms of tensile strength and is prone to breakage during construction. We need to find a tracer wire with a good combination of signal and strength.The following paper evaluates the resistance, tensile strength and signal properties of copper-clad steel tracer wire. We can find that copper-clad...Read More

Underground pipeline detector has two categories according to the principle of detection. One is pipeline detector. It can use electromagnetic induction principle to detect metal pipelines. Including electric / fiber optic cable, and some non-metallic pipelines with metal marker lines. The other is pipeline radar. It can use electromagnetic waves to detect all materials of...Read More

There are many different types of tracer wire that are often used in the current market. For example, copper-clad steel and copper-core polyethylene insulated cables, etc., these tracer wires in the actual application process, have their own benefits, but which tracer wire can meet the underground laying of gas pipeline tracer wire selection. Should also...Read More

Underground pipeline detection The classification and contents of underground pipelines are Power pipelines: including transmission and distribution cables, power cables, lighting cables and other pipelines.Telecommunications pipeline: including fiber optic cable pipeline, television pipeline, city telephone pipeline, long-distance pipeline, military communication pipeline and other pipelines.Water supply pipeline: including industrial and wine water, water transmission and distribution...Read More

Underground pipelines are an important part of urban infrastructure and a lifeline for the survival and development of cities.With the development of science and technology, the material of urban underground pipelines is also changing. In the past, a large number of metal pipelines were used, but now the application of plastic (polyethylene PE pipe, PVC...Read More
