3 PVCDrain pipe

PVCTube(full namePolyvinylchlorid),The main ingredient is polyvinyl chloride,Also add other ingredients to enhance their heat resistance、toughness、Damage。The uppermost layer of such a surface film is a paint,The main component of the middle is polyvinyl chloride,The lowermost layer is back binder。

(3mm id brass tube)According to the material characteristics:UPVCTube、PPTube、PETube、ABSTube。

UPVCTube

3mm id brass tube(3mm id brass tube)

1、Is a plastic tube,Adhesive adhesive at the interface,UPVCThe antifreeze and heat resistance of the tube are not good.,So it is difficult to use it as a hot water pipe,Since its strength cannot be applied to the pressure of the water pipe,So the cold water pipe is also very useful.。In most cases,PVCSuitable for wire pipelines and sewage pipes。

2、Characteristic:

  • Corrosion resistance(Not more fouling,Can inhibit bacterial growth)、Flexible、Light weight、Advantage of transportation,Special applicable to water supply pipe network。
  • It does not conduct electricity,Therefore, it is not easy to be with acid、Base、Electrochemical reaction in salt,acid、Base、Salt is difficult to corrode it,So there is no need for external anti-corrosion coating and lining。
  • Flexible,Can produce yield without rupture under load。I have made this test:Put oneDN50mmofUPVCPipe on the ground,Crown3.0The car is over.,Tube is just flat,But no broken。Then we let the Dongfeng cars full of carriers from the pipe,The same tube is only deformed without fragmentation.。
  • UPVCThe tube has a smaller elastic modulus to reduce the amplitude of the pressure impact to alleviate the impact of the water hammer.。

3、use:

  • ①、Water-saving irrigation pipeline,UPVCThe use of spray drops irrigation systems compared to ordinary irrigation,Water-saving50%-70%,At the same time, save fertilizer and pesticide,Crop production can be improved30%-80%。
  • ②、Construction pipe project。
  • ③、UPVCPlastic tube has excellent insulation capabilities,Also widely used as a post and telecommunications cable catheter。
  • ④、UPVCPlastic pipe-resistant、preservative,Many chemical plants used as infusion piping。Other use in chiseling works、Medical pipe project、Mineral saline transport pipeline、Electrical pipeline, etc.。

■ Copper pipe

3mm id brass tube

Plastic copper tube with pure copper(Copper)Tube,OverstockPEplastic,Plastic copper tube is slightly better than aluminum-plastic composite tube。For example, strength is better,Longer life,Heat resistance is also better。But the thermal insulation performance is slightly poor。 Pure copper has extremely high corrosion resistance,After using a period of time,A layer of green oxide occurs in the inner surface。But the life of the pipe、flow、And resistance to fluid,Basically, there is no impact。Copper green is healthy to human body health,And there is a certain killing ability to bacteria。 The installation method of the plastic copper tube has two types of card sets and welding.,Welding is more reliable。Copper can inhibit bacteria growth,99%Bacteria in the copper pipe5Disappeared after an hour,Ensure cleaning and hygiene of drinking water。

■ Dimen plastic galvanized cast iron pipe

3mm id brass tube

Wide plastic in a normal galvanized pipe inner wall,Make it with corrosion resistance,Small resistance、Insulation,At the same time, there is a characteristic of high strength of galvanized tube itself.。Most of this pipe uses ribbed connections。
