自來水用tpep防腐鋼管直縫鋼管、螺旋鋼管等各種管道都可以加工。而美國的相關專利USB公開了一種鋼管防腐內部冷卻方法，該方法在鋼管內部放入水泵，在鋼管轉動過程中向鋼管內壁噴水，鋼管和防腐層的冷卻順序為:鋼管、FBE層、膠粘劑層和PE層。如薄點低于規定厚度,則為不合格,再抽查根，其中根仍末合格時,全部為不合格。鑒于水泥砂漿具有上述優點，其防腐的功能和經濟性，被越來越多的國內外的工程技術部門認可，國內大中城市都使用水泥砂漿作為給水金屬管道內防腐的主要受點。
    自來水用tpep防腐鋼管環氧樹脂粉末涂層首要缺陷是膜較薄，易受外傷，呈現砂眼，制造技術要求高，設備也較雜亂，野外施工辦理難度大。不盡相同研發設計廠家，乃至不相同批次的產品功能差異較大，挑選時應著眼于其機械功能和密合性等。除了耐熱性外，無論是作為防腐資料仍是防腐體系都劣于聚乙烯。就此導致涂得太厚的當地涂層厚度超過規范，構成現象；而涂得太薄或沒有涂到的當地會構成鋼管防腐才能下降，致使終究發作銹蝕的現象。（2）防腐劑掛滴。防腐劑像水滴相同凝結在鋼管外表則變成是防腐劑掛滴現象，這種現象的發作時時沒有直接關聯到防腐性，也一樣要確保鋼管必定要求的防腐蝕力；可是從美觀的角度來看，有防腐劑掛滴的鋼管看上去不光澤，不均勻，直接影響了鋼管的外觀。
