Q:Natural gas aluminum pipe, what fittings are best used?
Special pipe fittings for copper plastic aluminium tube.The aluminum plastic pipe is a composite pipe which is welded longitudinally by an intermediate aluminum pipe and is lined with polyethylene plastic inside and outside, and is bonded with hot melt adhesive between the layer and the layer. According to the use of classification, there are ordinary drinking water pipes, high temperature pipes, gas pipes. Gas aluminum composite pipe has yellow Q mark, mainly used to transport natural gas, liquefied petroleum gas and gas pipeline system. Because the middle layer of aluminum plastic pipe is made of aluminum, the permeation of gas on plastic can be avoided, so the utility model is more suitable for gas pipelines.
Q:Can aluminum plastic pipe be connected by hot melt?
The inner and outer layers of aluminum plastic pipe are special polyethylene materials, clean, non-toxic and smooth. More than fifty years can be used. The intermediate aluminum layer is 100% permeable to gas and allows the tube to have both the advantages of metal and plastic tubing in addition to its respective disadvantages.
Q:Who knows how the double IGBT of the electromagnetic oven forms a composite tube?
IGBT is a composite tube consisting of a SHM (bipolar power high speed switching tube) and a MOS (insulated gate type FET), and the connection is similar to that of Darlington transistors. Among them, SHM is a current controlled transistor, and MOS is a voltage controlled transistor, so it is called full control.
Q:What is the thermal fuse sleeve of the wire mesh plastic composite pipe?
Hot melt connection quota of plastic pipe.
Q:What's the difference between a steel skeleton pipe and a steel mesh frame?
The steel skeleton plastic composite pipe has some disadvantages compared with the steel wire frame plastic composite pipe:1, connection mode. The steel skeleton plastic composite pipe needs a sleeve directly on the butt welding capacity of the two pipe, and the cost is higher2, the external interface of the steel plate exposed, easy to rust.
Q:What is a steel plastic composite pipe?
Steel plastic composite pipe, referred to as PSP; in the seamless steel pipe or welded steel pipe inner wall coating, high adhesion, corrosion, polyethylene powder coated or health food type epoxy resin coating is the upgrading of traditional galvanized pipe.
Q:What is the difference between stainless steel pipe and stainless steel composite pipe?
Stainless steel composite pipe in 2002 GB/T18704-2002 national standard formally promulgated, choose from the quality of materials, inspection and other aspects have a set of strict management, due to the advantages of beautiful appearance, low price, which has been widely used in bridge guardrail, decoration, vehicle accessories, conveying roller, the field of textile machinery accessories etc..
Q:What is a PE composite pipe?
Small diameter steel plastic composite pipe pipe prices more expensive than PE, and the General PE pipe hot melt connection is good, want to buy PE plastic composite pipe fittings connection.
Q:Do floor heating with aluminum pipe, why is it best?
My personal feeling is that the aluminum pipe is much better than PPR and many other things..Our home is made of Meifeng, we are with them the land of the total Meifeng contact, we believe that government. So why our local HVAC company aluminum pipe sales are particularly good?. Special day abundant this brand. Secondly, Meifeng, really very fire.
Q:How can the stainless steel composite pipe be welded?
The backing layer adopts melt-through bead welding process, the welding position is generally fixed, difficult to weld, welding layer is composite pipe to meet the highest quality requirements of the process, the technical level of the welder must have a strong and high sense of responsibility. Must be on the inside of the pipe before welding, argon weld filling 99.99% time tester oxygen content from the source of deep groove gap gas extraction measurement of internal oxygen tube, when the oxygen content is less than 50ppm at the start of the bottom in order to ensure the welding quality by tungsten arc welding by self to symmetry, before welding sealing; welding welding layer was burnished.
The company products are strictly produced as the standard of international, country and industry etc. And has already passed the test of national, provincial, municipal and other authority departments testing. Since the products put on the market, we own a good name in china and abroad.The products range has been changed from single into series. Now the company has become a high-tech modern enterprise of scientific research, development, production, marketing, trade and services.
