    Anti-aging

    29 Dec 2018

    Anti-aging, long service life: Polyethylene pipes containing 2-2.5% of uniformly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation. Good wear resistance: The comparison of wear resistance of HDPE pipe and steel pipe shows that the wear resistance of HDPE pipe is 4 times that of steel pipe. In the field of mud transport, HDPE pipes have better wear resistance than steel pipes, which means HDPE pipes have a longer service life and better economy. Good flexibility: The flexibility of the HDPE pipe makes it easy to bend. In engineering, the obstacle can be bypassed by changing the direction of the pipe. In many cases, the flexibility of the pipe can reduce the amount of pipe and reduce the installation cost. Small water flow resistance: The HDPE pipe has a smooth inner surface with a Manning coefficient of 0.009. The smooth performance and non-adhesive properties ensure that the HDPE pipe has a higher conveying capacity than...

    Performance

    22 Dec 2018

    Performance A good pipe should not only have good economy, but also have a series of advantages such as stable and reliable interface, material impact resistance, crack resistance, aging resistance and corrosion resistance. Compared with traditional pipe, HDPE pipe system has the following one. Series advantages: (1) Reliable connection: The polyethylene pipe system is connected by electric hot melt method, and the strength of the joint is higher than the strength of the pipe body. (2) Good low temperature impact resistance: The low temperature embrittlement temperature of polyethylene is extremely low, and it can be safely used in the temperature range of -60-60 °C. In winter construction, due to the good impact resistance of the material, the tube will not be brittle. (3) Good resistance to stress cracking: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and environmental stress cracking resistance is also outstanding. (4) Good chemical resistanc...

    Connection steps

    14 Dec 2018

    Such as: rotating cutter to cut the pipe; rotary scraper - scrape the scale on the surface of the pipe; climb the wall scraper - scrape the skin on the surface of the large diameter pipe; gas shut-off tool - to achieve the off-site operation. Connection steps: 1. Clamp and clean the port 2. Adjust and smooth the port 3. Port alignment 4. Pressure welding 5. Pressure relief cooling Application areas: ■ Urban water pipe network system. ■ Urban and rural drinking water pipelines. ■ Liquid transportation pipelines for chemical, chemical fiber, food, forestry, printing and dyeing, pharmaceutical, light industry, paper, metallurgical and other industries. ■ Agricultural irrigation pipelines. ■ Post and telecommunications lines, power line protection sleeves. ■ Mine mortar conveying pipeline. ■ Post and telecommunications lines, power line protection sleeves. Technical Regulations: CJJ101-2004 (Technical Regulations for Buried Polyethylene Water Supply Pipeline Engineering)

    Characteristics

    08 Dec 2018

    Characteristics ■ Good hygienic performance: PE pipe processing does not add heavy metal salt stabilizer, the material is non-toxic, no fouling layer, no bacteria, and it solves the secondary pollution of urban drinking water. ■ Excellent corrosion resistance: It can resist the erosion of many chemical media except a few strong oxidants; there is no electrochemical corrosion. ■ Long service life: PE pipes can be safely used for more than 50 years under rated temperature and pressure conditions. ■ Better impact resistance: PE pipe has good toughness and high impact strength. Heavy objects directly press through the pipe and will not cause pipe rupture. ■ Reliable connection performance: The strength of the PE tube hot melt or electrofusion interface is higher than that of the pipe body, and the joint will not be broken due to soil movement or live load. ■ Good construction performance: the pipeline is light in weight, the welding process is simple, the construction is convenient, and th...

    Introduction

    30 Nov 2018

    Introduction Polyethylene pipe (PE pipe) English name: Polyethylene PE pipes are used in a wide range of fields. Among them, water supply pipes and gas pipes are the two largest application markets. PE resin is polymerized from monomeric ethylene. Due to different polymerization conditions such as pressure and temperature during polymerization, resins of different densities can be obtained, and thus high density polyethylene, medium density polyethylene and low density poly are obtained. The fraction of ethylene. When processing different types of PE pipes, depending on the application conditions, the resin grades are selected differently, and the requirements for extruders and molds are also different. Internationally, the material of polyethylene pipe is divided into five grades of PE32, PE40, PE63, PE80 and PE100, and the materials used for gas pipes and water supply pipes are mainly PE80 and PE100. China does not classify special materials for polyethylene pipes, which makes it dif...

  • Operation points of steel butt welding machine

    Operation points of steel butt welding machine

    24 Nov 2018

    Operation points of steel butt welding machine The welder operator must be professionally trained, familiar with the welder construction, performance, operating procedures, and master the knowledge of process parameters selection, quality inspection specifications. Before operation, check whether the welding machine mechanism is sensitive and reliable, whether the electrical system is safe, whether the cooling water pump system has water leakage, and whether the lubrication parts are well filled. It is strictly forbidden to weld steel bars exceeding the specified diameter. The main ribs must be welded and then cold drawn. In order to ensure the quality of the welding, it is necessary to carry out cleaning, rust removal and correction in the range of about 150 mm. When working with the operator, you must bring colored protective glasses and hats to prevent the eyes from irritating the eyes and molten metal from burning the skin. The butt welder should be parked in a clean, dry and venti...
