性能简介
    一、 聚四氯乙烯,简称ITFE、F4:使用温度-200-+260℃。
聚四氯乙烯具有非常优良的耐蚀和耐热性能,除熔金属锂、钾、钠、三氟化氯、高温下的三氟化氧、高流速的液氟外,它几乎可以抵抗所有化学介质(包括浓硝酸和王水)它可以长期在230~260℃下操作,耐热性超过大多数塑料。它有优良的电性能、抗粘性和低摩擦系数。
二、 聚丙烯简称PP:使用温度-14-+120℃。
    聚丙烯是热塑性塑料,耐蚀性和聚乙烯相似,且较优。比重小,强度高于聚乙烯。常温下耐冲击性能良好,0℃以下变差 ,耐温性高、在低应力下可长期使用于110~120℃。因此广泛用于聚乙烯和聚氯乙烯不适用的较高温度的环境。其耐腐蚀性能,除浓硝酸、发烟硫酸、氯磺酸等强氧化性酸外,能耐大多数的有机和无机酸、碱和盐,也适于在室外大气中暴露(加入2﹪碳黑的品种)。对应力腐蚀破裂的抗蚀性良好,但能被某些强有机溶剂破坏。
三、 聚乙烯简称PE,PO:使用温度(低密度)-70-+60℃。
    聚乙烯具有良好的耐蚀性。对非氧化性酸(如盐酸、稀硫酸、氢氟酸)稀硝酸、碱和盐溶液都有良好的耐蚀性,但不耐浓硝酸,浓硫酸和其它强氧化剂的腐蚀。对有机熔剂常温下一般耐腐蚀性良好,但有些熔剂能使其溶胀,在外或内应力存在下。有些挥发性液体或蒸汽可使它产生应力腐蚀破坏。
四、 钢塑管附件
    钢塑管附件包括标准三通、四通、弯头、异经管等,它采用与钢塑复合管相应的材质、尺寸和复合管配套供应,并有相同的抗腐能力。互换性、通用性能都很强。
    One. Forgathers four vinyl chlorides,For short ITFE,F4;Uses temperature200-+will be 260℃ .
Forgather four fluorine ethylenes possess very fit erosion resisting and heatproof performance,Except melts metal lithium.Potassium,Sodium,Three fluorines melt chlorine’s three fluorines melt oxygen under high temperature,Outside high streamflow’s liquid fluorine,It almost can resist all chemistry carrier(lnclude thick nitric acid and aqua regia)It will can  long-term 260℃urder operation at 230,Heat-resistance exceeds most plastics.It has fit electicity performance,Resist viscosity and low coefficient of friction.
Two,Polypropylene fors short PP .Uses temperature-14-+will be 120℃.Polypropylene is thermoplastic plastic.Erosion resisting sex and polyethylene similar.And compare excellence.Proportion small, lntension highers than polyethylene.Endures impact performance good under normal temperature,0℃will change poor.Endures wen xing highness,Can long-term use in 100 120℃at will be low stress under.So extensive be used for polyethylene and PVC inapplicable compare high temperature’s environment.It endures corrosion behavior.Except thick nitric acid,Sends smoke sulphuric acid,Chlorine sulfonic acid strong oxidizes sex sour outside.Ability most organic and mineral acid,Alkali and salt,Also appropriates to debunk in outdoor atmosphere(Joins 2%charcoals blak breed).Parallels stength corrode disruptive resist corrasion sex excellently,But canned was some strong organic solvent breakage.
Three,Polyethylene Jane PE,PO.Uses temperature(Low density)-70-+will be 60℃.
Polyethylene possesses fit erosion resisting sex.To not oxidizes sex sour(Is like hydrochloric acid,Rare sulphuric acid,Hydrofluoric acid)Rare nitric acid,Alkali and brine solution all have good erosion resisting sex,But not does endure thick nitric acid.Concentrated acid and other strong oxidant’s cauterization.To ordinary endures causiticity good under organic solvent normal temperature.But some solvent can make it dissolve bloated.Out or body stress exists under.Some valatile liquid or steam can make it bring forth stress cauterization breakage.
Four,Gang su guan accessory
    Gang su guan accessory include standard san tong,Sitong,Elbow,Difference path tube,It adopts with steel model compound administer corresponding material quality,Size and compound tube form a complete set supply,And has same resist rotten ability.Exchange sex,Generality all very strong.
