鋼絲網(wǎng)骨架塑料復(fù)合管是一款改良過的新型的鋼骨架塑料復(fù)合管。這種管材又稱為srtp管。這種新型管道是用高強(qiáng)度過塑鋼絲網(wǎng)骨架和熱塑性塑料聚乙烯為原材料，鋼絲纏繞網(wǎng)作為聚乙烯塑料管的骨架增強(qiáng)體，以高密度聚乙烯（HDPE）為基體，采用高性能的HDPE改性粘結(jié)樹脂將鋼絲骨架與內(nèi)、外層高密度聚乙烯緊密地連接在一起，使之具有優(yōu)良的復(fù)合效果。因為有了高強(qiáng)度鋼絲增強(qiáng)體被包覆在連續(xù)熱塑性塑料之中，因此這種復(fù)合管克服了鋼管和塑料管各自的缺點(diǎn)，而又保持了鋼管和塑料管各自的優(yōu)點(diǎn)。
鋼絲網(wǎng)骨架塑料復(fù)合管，采用了優(yōu)質(zhì)的材質(zhì)和先進(jìn)的生產(chǎn)工藝，使之具有更高的耐壓性能。同時，該復(fù)合管具有優(yōu)良的柔性，適用于長距離埋地用供水、輸氣管道系統(tǒng)。鋼絲網(wǎng)骨架聚乙烯復(fù)合管采用的管件是聚乙烯電熔管件。連接時，利用管件內(nèi)部發(fā)熱體將管材外層塑料與管件內(nèi)層塑料熔融，把管材與管件可靠地連接在一起。
外觀：管材內(nèi)外表面應(yīng)平整光滑，色澤均勻，不得有鋼絲裸露及明顯的劃痕、氣泡等缺陷。
