PPglobe valve，PPManual ball valve，PPFlange ball valve，Polypropylene ball valve。Quality valve supplier，Pure material productionPPglobe valve，national standardPPglobe valve，The factory can only be delivered after passing the strict inspection by professional personnel，Reliable quality！ The ball valve is not only simple in structure、Good sealing performance，And in a certain range of nominal diameter, the volume is small、Light weight、Less material consumption、Small installation size，And the driving torque is small，It is easy to operate、Easy to realize quick opening and closing，It's near One of the fastest growing valve varieties in the past ten years。Ball valve is evolved from plug valve，Its hoist is a sphere，Use the ball to rotate around the axis of the stem90°Achieve the purpose of opening and closing。The ball valve is mainly used for cutting off in the pipeline、Distributing and changing the direction of medium flow，Designed asVThe ball valve with U-shaped opening also has good flow regulation function。

PPThe pipe fittings are produced according to the standard。Tube products by injection、Compression molding、Welding forming，smooth surface ，Color uniformity 、Reasonable structure。The main types of pipe fittings are：flange、Connector、Elbow、tee、reducing pipe、Welding rod, etc。Complete varieties and specifications，Production of pipe fittings with the same material as pipes，The working pressure meets the requirements of pipe network pressure。

PPraw material，Chemical name：polypropylene，characteristic：Low density，The strength is rigid，The hardness and heat resistance can be obtained in100It is used at about 90 degrees。

Performance characteristics

1 Jingran environmental protectionPPPipe fittings

physical property

：

Polypropylene is odorless、Tasteless milky white high crystalline polymer，At present, it is one of the light plastics。It is stable to water，The water absorption in water is0. 01%。Good formability

2Jingran environmental protectionPPPipe fittingsmechanical property ：

Higher parts，It is difficult to meet the requirements，The surface of the product is glossy，Easy to color。Polypropylene has high crystallinity，Regular structure，So it has excellent mechanical properties。strength，But with the increase of isotactic index，Material

impact strength

There has been a decline，But it doesn't change when it drops to a certain value。Temperature and loading rate have great influence on the toughness of polypropylene。

3Jingran environmental protectionPPPipe fittingsThermal performance：

Polypropylene has good heat resistance，Products can be sold in100℃The above temperature should be disinfected，

chemical stability：

Polypropylene has good chemical stability，In addition to concentrated sulfuric acid、Erosion of outer wall by concentrated nitric acid，For other kinds of

Chemical Reagents

All of them are relatively stable；So polypropylene is suitable for making all kinds of chemical pipes and fittings，Good anti-corrosion effect。

Electrical properties：

It has a high dielectric coefficient，And with the increase of temperature，It can be used to make heated electrical insulation products。Its breakdown voltage is also very high，Suitable for electrical accessories, etc。Withstand voltage、Good arc resistance，But the static electricity is high，Contact with copper is easy to aging
