目前濟南市面上正規的防水套管廠家其實并不多，我們永旺作為一家生產了十幾年的防水套管廠家，質量可靠價格便宜，所謂防水套管就是在套管外壁增加不少于1圈的防水翼，這樣套管澆筑在墻體內時就成為一個整體，不會因脹縮因數而出現裂紋而滲漏。

　　At present, there are not many legitimate waterproof sleeve manufacturers on the market in Jinan. As a waterproof sleeve manufacturer that has been producing for more than ten years, Yongwang is reliable in quality and cheap in price. The so-called waterproof sleeve is to add at least one circle of waterproof wings on the outer wall of the sleeve, so that when the sleeve is poured into the wall, it becomes a whole and will not crack and leak due to the expansion and contraction factor.

　　一般在做水池的時候要用到套管，它是管道通向水池的通道。但是普通的套管很難密封，以致套管與管道之間會有漏水、套管與墻壁之間也易漏水。只用防水套管，可以解決套管與墻壁之間的漏水，但不能解決套管與管道之間的密封，柔性防水套管正好可以解決兩種問題。

　　Usually, when making a pool, a sleeve is used, which is the passage from the pipeline to the pool. However, ordinary casing is difficult to seal, resulting in water leakage between the casing and the pipeline, as well as water leakage between the casing and the wall. Using only waterproof sleeves can solve the leakage between the sleeve and the wall, but it cannot solve the sealing between the sleeve and the pipeline. Flexible waterproof sleeves can precisely solve two problems.

　　非標則是在外形和大概結構符合標準圖集的情況下，選材時對法蘭厚度、翼環厚度、管徑與厚度認為放寬要求，嚴格來說，這些是不合格的產品，當然，一定程度內的放寬標準不至于影響使用，但過分的放寬標準則回影響到使用性能。

　　Non standard products are considered to have relaxed requirements for flange thickness, wing ring thickness, pipe diameter and thickness when selecting materials, provided that their appearance and approximate structure comply with the standard atlas. Strictly speaking, these are unqualified products. Of course, a certain degree of relaxation of standards will not affect use, but excessive relaxation of standards will affect performance.

　　總的來說，想要采購防水套管，一定要選擇好的廠家，這樣才能放心，質量和售后服務上才能可靠，歡迎大家前來咨詢了解。
