Application of induction heating in steel pipe processing
Steel-plastic composite pipe, because of its excellent corrosion resistance, good circulation capacity, not easy to scale, long service life, etc., replaced galvanized steel pipe, widely used in construction water supply projects in recent years. Moreover, the state expressly stipulates that zinc pipes should not be used for water supply pipes, so the steel-plastic composite pipe market has broad prospects.
In the process of lining plastic pipe processing, the PE pipe inside the galvanized steel pipe is uniformly and stably welded to the inner wall of the galvanized steel pipe, which is a decisive factor determining the quality of the steel-plastic composite pipe. The heat welding is currently used more.
The practice of most enterprises is to install PE pipe and pass the high-pressure air steel-plastic composite pipe semi-finished products, and send them in batches, such as large-scale heating furnaces (heating furnaces are preheated through the burners in advance), after a period of baking, After the entire batch of products reaches the set temperature, the steel-plastic composite pipe is taken out for subsequent processing.
This heating method is first of all a large area of ​​equipment and a high input cost. Only the floor space of the oven is nearly 100 square meters, and there are a lot of production space including auxiliary equipment such as ventilation equipment, combustion equipment, and work bench. More importantly, when the equipment is turned on, it must be preheated in advance, and the temperature of a near-hundred cubic meter space is heated to the required temperature in advance, which requires a lot of energy, and when the work is finished, the heat energy will be wasted. . In an era of high oil prices, this is undoubtedly a waste.
Due to the large furnace cavity, when a large number of steel-plastic composite pipes are placed therein, the uneven heating of the outer wall of the pipe will inevitably lead to foaming and wrinkling of the inner layer of the composite pipe, which affects the quality.
Guangzhou Weishida Electronic Technology Co., Ltd. is a professional enterprise engaged in the research and development of induction heating technology products. The company's existing high-frequency, super-audio, medium-frequency induction heating equipment, high-frequency welded pipe and plastic-lined (steel-plastic) pipe equipment, etc. more than 50 types of products, widely used in fasteners, tools, hardware tools, stainless steel products, die-casting , aluminum profile manufacturing, automotive and motorcycle parts, pipe processing and other industries.
The new lining plastic (steel-plastic) pipe equipment with the high-power induction heating machine produced by our company has the advantages of energy saving, environmental protection, convenient operation and small floor space. It is a furnace that successfully replaces fuel and gas as heat source. Lining plastic (steel-plastic) pipe equipment is the best choice for you to reduce costs, improve product quality, improve economic efficiency and competitiveness.
Furnace-type lining plastic (steel-plastic) pipe equipment with fuel and gas as heat source has the following advantages.
1. Energy saving cost: This equipment mainly uses induction heating device as heat source. It has start-stop instant completion, no need to preheat, electro-thermal conversion efficiency is over 95%, no heating and no energy consumption, small batch orders can also be accepted.
2, the operation is convenient and flexible: only need to adjust the travel speed of the heating power, you can process different pipe products, the consistency of product quality is high. PLC control, high degree of automation, convenient control, can store different heating parameters of products, easy to process and produce.
3, the product quality is good: because induction heating only has a role in the metal, no effect on the plastic material lining the inner wall, so the inner wall of the lining plastic pipe has no protrusions, bubbles or other phenomena that impair the appearance quality, and the plating of the galvanized pipe The zinc layer has no effect.
4. Low equipment investment: about 1/20 of the furnace-type plastic (steel-plastic) pipe equipment with only fuel and gas as heat source. The whole equipment covers a small area / only 1.6X8.5 meters, the main heating power supply occupies less than 1 square meter, saving production space, wide adaptability can meet the pipe lining plastic processing of 15-500MM, easy maintenance.
5. Customers can choose different main heating power sources according to their own scale, output, power supply and other factors. The output power of the induction heating machine produced by our company is from 15KW to 600KW, with stable performance and reliable quality. It is the most performance in the same industry in China. One of the good products.
Supporting SSF-80A super-audio induction heating machine (maximum output 80KW) lining plastic pipe processing equipment, processing the following steel-plastic composite pipe heating time:
Φ300×6.00×6000, 4 minutes and 20 seconds, power consumption 5.7 degrees
Φ250×5.00×6000 3 minutes 10 seconds Power consumption 3.8 degrees
Φ 80×4.00×6000 40 seconds Power consumption 0.9 degrees
Stainless steel square nut have good chemical resistance and may be mildly magnetic. Large flat sides make them easy to grip with a wrench and keep them from rotating in channels and square holes.They`re easily gripped with a wrench due to their flat, broad sides, which also prevent them from rotating in channels and square holes. Compared to hex nuts, a greater area is in contact with the fastened surface. And compared to steel nuts, they`re slightly less strong.
Square nuts are a type of fastener that have a square shape. They are typically used with bolts or threaded rods to secure objects together. Square nuts have four flat sides and are designed to be tightened or loosened with a wrench or pliers. They are commonly used in applications where a regular hex nut may not fit or provide enough grip. Square nuts are often used in woodworking, construction, and machinery industries.
Stainless steel fasteners are hardware components made from a corrosion-resistant alloy of steel and chromium. They are commonly used in various industries and applications due to their durability and resistance to rust and staining.
