The warning zone, also known as the marking tape, is made of PE material and is widely used in various gas pipelines, oil pipelines, urban water supply and drainage, gas-liquid pipeline transportation systems, power cables, telecommunication optical cables, etc. The transport system and confidence transmission system for national economy and people's livelihood Warning protection. Especially for complex urban pipe network construction sites, road construction sites, traffic accidents in county towns protection, construction and construction sites, direct buried pipelines in the field has a clear protective warning, warning tape with PE material, good corrosion resistance Sex, service life 30-50 years.
The construction of warning strips is convenient. The construction and embedding are carried out at the same time. It is buried between the ground and the pipeline. It is placed 30-50cm above the pipeline and serves as a warning sign to avoid unnecessary damage to the pipeline during future excavation construction. It is an economical and effective and easy-to-follow supply of various direct-buried pipelines and cables for accidents and avoiding huge losses of property and economic losses due to accidental damage.
The finished product has the characteristics of low cost, light weight, high flexibility, no corrosion, long service life, convenient construction, etc. It can accurately detect the laying of various types of buried underground pipelines without excavation of the target embankment before construction. Location and arrangement. Widely used in a variety of underground pipelines such as gas, electricity, telecommunications cables, water pipes and so on. It can effectively prevent the damage caused by the excavation of the pipelines that have been laid and blindly and undisturbed when new pipelines are laid and cause unnecessary casualties or economic losses, which has good use value.
The warning band is divided into ordinary warning band and detectable warning band. The middle sandwich layer of the detectable warning band has an aluminum foil with a width of about 5-8cm. After laying, the metal detector can detect the warning at a height of about 10cm from the ground. With the direction of the belt, you can know the direction of the pipeline.
The detectable buried warning tape is a metal-detectable warning tape , also called tracer tape . (Centimeter contains metal wire, which can play a detection effect), and the product uses high-strength, anti-aging polymer materials, with PE, PP, OPP as the main raw material, processed by anti-corrosion treatment, corrosion resistance, bright color, eye-catching, long-term laying in the ground for 50 years without corrosion, do not fade. Generally, the number of years laid in the underground is about 50 years, which meets the constant requirements for long-term buried quality. With the continuous development of the social economy, more and more plastic pipes such as PE, PPR, and PVC are used in the construction of underground pipe networks. The detection equipment cannot detect the direction of the pipeline at all, and the metal warning band can solve the problem that the pipeline cannot be detected. It is convenient for construction to detect the location of underground pipelines, water pipelines, etc. in order to avoid unnecessary trouble during construction, which brings great convenience to construction workers.
The machine applies tension, compression, bending, and shear forces to test the strength, elasticity, and durability of various materials such as metals, plastics, textiles, rubber, ceramics, and composites. It can measure parameters such as tensile strength, yield strength, elongation, modulus of elasticity, and fracture toughness.
A typical UTM consists of a load frame, grips or fixtures to hold the specimen, a load cell or force transducer to measure the applied force, and a displacement transducer to measure the deformation or displacement of the specimen. The machine is controlled by a computer or a control unit that allows the user to set the testing parameters and record the test data.
