What are the pre-use maintenance and precautions for plastic-lined pipe fittings?
Everyone knows the importance of pipelines in our lives. Many jobs can only be carried out through pipelines, such as underground pipelines and liquid transportation. Our lives are inseparable from the use of pipelines. With the rapid development of science and technology, many new types of pipes have appeared on the market one after another. […]
The processing method of plastic-lined steel pipe determines its performance
The forming principle of plastic-lined pipes used in water circulation transportation: The steel-lined plastic pipe adopts the original steel body, electric furnace heating, plastic material inner filling centrifugal molding and external hot compress centrifugal processing, and the sealing surface of the connecting flange needs manual hot compress molding. All pipelines and water contact surfaces are […]
What are the advantages of UHMWPE tunnel escape pipes?
Ultra-high molecular weight polyethylene tunnel escape pipeline has excellent comprehensive performance, and has unparalleled impact resistance, compression resistance, abrasion resistance, aging resistance, light weight, chemical resistance, sanitation and non-toxicity. It is not easy to adhere and is called “magic plastic” in the world. Therefore, it has broad prospects for citation in the fields of machinery, […]
What are the uses of ultra-high polymer pipes?
Ultra-high polymer pipes are called non-metallic pipes, which should belong to plastic products. The raw material of ultra-high polymer pipes is PE, but the molecular weight is much higher than ordinary molecular weight, and the performance is better than ordinary PE materials, such as: wear resistance and resistance Corrosion, impact resistance, yield strength and breaking […]
What are the commonly used pipeline anticorrosive coatings?
Classification of pipeline anticorrosion Pipeline anti-corrosion is divided into pipeline main body anti-corrosion and patch weld anti-corrosion How to choose pipe repair materials? It depends on the material of the main pipeline anti-corrosion layer. Commonly used mending methods include petroleum asphalt mending, epoxy coal tar mending, adhesive tape mending, powder epoxy mending, and PE heat […]
what is cathodic protection？the methods to realize cathodic protection of underground pipelines and its technical requirement
Due to the long pipeline construction period, it is generally required if the soil resistivity is less than 20Q. m, it is necessary to install a magnesium anode for temporary protection and connect it to the pipeline through a test pile. When the impressed current cathodic protection is put into use, the temporary protection is […]
what is Pipeline Anticorrosion? Pipe Anti Corrosion Type and Process Flow
Description of pipeline anti corrosion Pipeline anti corrosion is a measurement to slow down or prevent corrosion and deterioration of the pipeline under the influence of chemical or electrochemical action or the metabolic activities of microorganisms What is pipeline corrosion phenomenon? Corrosion can be understood as a chemical reaction of materials in the environment in which […]

what is YK30 tool steel ? Applications and heat treatment of YK30 steel
YK30 steel is an oil-quenched carbon tool steel, often used in stamping dies, fixtures, gauges, paper knives, auxiliary tools, etc. Characteristic Vacuum degassing refined steel with stable quality; Good hardenability, oil-cooled hardening (less quenching and deformation); Good toughness and wear resistance, durable tools; YK30 adds Mn and Cr on the basis of SK105 to improve […]
How are seamless steel pipes produced?
How are seamless steel pipes produced? The production process of seamless steel pipes is mainly divided into two types: cold-drawn and hot-rolled. The production process of cold-rolled seamless steel pipes is more complicated than that of hot-rolled steel pipes. The pipe billet must firstly be under three-roll continuous rolling, and then sizing test after extrusion. If […]
Two important factors that affect welding of steel and aluminum
Steel and aluminum have different chemical and physical properties, such as melting point, thermal expansion coefficient, elastic modulus, etc. When welding steel and aluminum by hot working welding process, they will face many problems, that is, aluminum and steel are prone to form very hard and brittle IMP phases (Intermetallic phase), the greater the welding […]
