<div class="time">作者：零遠環保???時間：2021-08-17 15:31:23</div> <div class="new_conts" id="new_conts"> <p>　　pp管是現在使用較為頻繁的一種管材，具有很強的抗腐蝕和老化性，但是有時在使用過程中，由于管材長度不夠或是其他原因，都需要對管材進行熱熔連接，然而為了保證連接安全，具體的注意事項如下：</p><p>　　1.熱熔工具接通電源，達到工作溫度，指示燈亮后方能開始操作。</p><p>　　2.切割管材，須使端面垂直于管軸線。管材切割一般使用專用剪刀或管道切割機，需要時使用鋒利的鋼鋸，但切割后管材斷面應去除毛刺。</p><p>　　3.pp管材和管件連接端面須清潔、干燥、無油污。</p><p>　　4.熔接彎頭或三通時，按設計圖紙要求，應注意其方向，在管件和管材的直線方向上，用輔助記號標出其位置。</p><p>　　5.連接時，無旋轉地把管端導入加熱套內，插人到標準的深度，同時，無旋轉地把管件推到加熱頭上，達到規定標志處。</p><p>　　6.到加熱時間后，立即把管材與管件從加熱套與加熱頭上同時取下，迅速無旋轉地直插到所標深度，使接頭處形成均勻凸緣，此時接頭可以校正，但嚴禁旋轉。</p><p>　　7.待達到規定冷卻時間后，將管件蓋扣在管件上。</p><p>　　當我們在進行PP管的熱熔連接時，一定要控制好管材的加熱溫度、冷卻時間、管材切割等方面，從而保證管材的連接質量，確保使用無誤。</p><p><br/></p></div>
