Pre-insulated Pipe Fabrication
Pre-insulated, pre-fabricated jacketed piping system is used for industrial and commercial applications. Pre-Insulated, pre-jacketed thermal pipe has a definite advantage over field installed insulation and jacketing. All straight sections of the factory preinsulated piping system shall be jacketed with a High Density Polyethylene (HDPE) jacket conforming to ASTM D1248,PVC jackets shall not be allowed.
All field butt joints shall be made in straight sections of pipe.here for welding polyethylene, it can use field hdpe pipe Butt Fusion Machines according to pipe range. For PE Pre-insulated pipe fabrication, It will use workshop fitting machines for bend fabrication of plastics. How it works? Firstly you need to prepare pe pipe Angle Cutting Saw and fix thin pipe on sepcial clamp, and then cut hdpe pre-insulated pipe in required angle. Then move this pipe and fix them on elbow clamps of pre-insulated fitting welding equipment. Special half heating plates positioned on top of the welding zone are used to ensure the required welding temperature, The appication of uniform welding pressure which is controlled hydraulically, ensures the quality of the weld between the sleeve and the pipe casing. The welding phases of pipe fabrication are below: 1. Approaching and preheating 2: Heating 3.Removing the heating element 4. Reaching the welding pressure 5.Welding 6. Cooling

The downstream sapphire industry is still dominated by LED substrate demand. From the perspective of LED application demand, due to policy promotion and LED price decline, global LED lighting has entered an accelerated penetration period, driving the growth of the entire LED market. According to the market capacity of LED substrate demand, according to the statistics and forecast of high-tech LED, in 2017, China MOCVD has a sapphire market structure: LED substrate application accounts for 80% of the market share. Sapphire is a collection of excellent optical properties, physical properties and The unique crystal of chemical properties is an important basic material for modern industry. Its unique lattice structure, excellent mechanical properties, and good thermal properties make sapphire crystals an ideal substrate material for practical applications such as semiconductor lighting (LED), large-scale integrated circuits SOI and SOS, and superconducting nanostructured films. At the same time, sapphire has high strength, hardness and erosion resistance. It is widely used as a screen material in smart equipment, infrared military equipment, satellite space technology, high-intensity laser window and other fields. According to the Prospective Industry Research Institute's "2018-2023 China Sapphire Industry Development Prospects and Investment Strategic Planning Analysis Report", LED substrate materials accounted for more than 80% of sapphire demand in the past three years, instead of LED applications. Accounting for 20% of sapphire demand, non-LED applications are mainly reflected in consumer electronics demand, such as: smart phone camera lens protection glass, Home button, sapphire crystal. Until now, LED substrate materials are still an important application for sapphire. Sapphire market demand 1 - LED substrate: Diamond wire market capacity is close to 500 million meters. The downstream sapphire industry is still dominated by LED substrate demand. From the perspective of LED application demand, global LED lighting has accelerated due to policy promotion and LED price decline. The penetration period will drive the growth of the entire LED market. According to the market capacity of LED substrate, according to the statistics and forecast of high-tech LED, in 2017, the number of MOCVD in China reached 1,534. The global LED industry will achieve an annual growth rate of 25%-30% driven by lighting, while the upstream sapphire industry will maintain a corresponding growth of around 30%. Considering that China's chip companies' operating rate and capacity utilization rate continue to increase, according to 2014-2017 80%, 90%, 90%, 90% of the equipment operating rate, 350 days of operation per year, 2-3 rounds per day The efficiency of the calculation is conservative. The global demand for sapphire substrates (in 2 inches) in 2014-2017 is 117,785,400 pieces/year, 148,361,200 pieces/year, 16269.72 million pieces/year, and 16,617,100 pieces/year. The wire diameter of the diamond wire is about 0.25mm. Cutting a 2-inch substrate consumes about 3 meters of diamond wire. According to this calculation, the diamond wire required for the global LED sapphire underlay in 2014-2017 is about 354 million meters and 445 million. Rice, 445 million meters and 4.9 million meters. Sapphire market demand 2 - Consumer electronics: Consumer electronics products have a market capacity of more than 100 million meters for diamond wire. According to French YOLE statistics, 2014-2017 LED substrate materials account for more than 80% of sapphire demand, not LED applications. About 20% of sapphire demand, non-LED applications are mainly reflected in consumer electronics demand. The market capacity of diamond wire for consumer electronics products in 2013-2017 is calculated as follows: In summary, with the rapid development of the LED industry, the acceleration of consumer electronic sapphire applications and the further increase in demand for defense industry materials and civil forms, the market The demand for sapphire materials will continue to grow rapidly. As a consumable for processing sapphire materials, the products have broad market prospects.
