Bisakah pipa PE panas diputar?

2025-08-19

Dalam pemasangan dan konstruksi pipa PE, sambungan lelehan panas adalah proses kunci untuk memastikan pengoperasian sistem perpipaan yang aman dan stabil. Banyak personel konstruksi akan menghadapi masalah umum: dapatkah pipa PE diputar ketika sambungan lelehan panas dibuat? Sebagai pipa AD dengan pengalaman yang kaya di bidang pipa plastik, berikut adalah analisis terperinci dari poin-poin utama operasi ini untuk Anda.

Pertama-tama, perlu untuk memperjelas bahwa pipa PE memiliki persyaratan yang berbeda untuk "rotasi" pada berbagai tahap sambungan lelehan panas.

Sebelum sambungan lelehan panas dimulai, yaitu tahap persiapan pipa dan alat kelengkapan pipa, perlu untuk menyelaraskan dan meluruskan permukaan ujung pipa PE untuk dihubungkan untuk memastikan bahwa kapak tumpang tindih. Pada saat ini, untuk mencapai efek penyelarasan terbaik, perlu, penyesuaian atau rotasi sudut kecil dapat dilakukan. Tujuannya adalah untuk membuat pipa dan permukaan pipa yang dilas pas sepenuhnya dan menghindari ketidakselarasan. Rotasi kecil pada tahap ini adalah untuk mempersiapkan kualitas pengelasan berikutnya dan diperbolehkan, tetapi rotasi skala besar yang tidak perlu harus diminimalkan.

Saat memasuki tahap pemanasan formal, yaitu, ketika ujung pipa PE terhubung ke cetakan lelehan panas untuk pemanasan, sangat dilarang untuk memutar pipa atau pemasangan pipa. Pipa PE dari pipa AD memiliki indeks peleburan dan stabilitas termal tertentu. Saat memanaskan, perlu memastikan bahwa permukaan yang dilas dipanaskan secara merata untuk membentuk cincin cair yang seragam. Jika berputar pada saat ini, itu akan menyebabkan pemanasan yang tidak merata, menghancurkan integritas dan keseragaman lapisan cair, dan kemudian mempengaruhi kekuatan pengelasan, yang dapat menyebabkan bahaya keselamatan seperti kebocoran pada antarmuka.

Setelah pemanasan selesai, lepaskan pipa PE dari kepala mati dan lakukan docking dengan cepat. Selama proses "beralih" ini, stabilitas pipa harus dipertahankan untuk menghindari rotasi yang disebabkan oleh gaya eksternal atau beratnya sendiri. Saat berlabuh, tekanan harus diterapkan dengan lancar dan merata di sepanjang arah sumbu, sehingga kedua wajah ujung cair dipasang erat. Proses ini juga tidak diperbolehkan untuk berputar. Setiap rotasi dapat menyebabkan lapisan cair yang terbentuk dipelintir dan dipindahkan, mengakibatkan cacat pengelasan.

Setelah docking selesai, masuk ke tahap penahan tekanan pendinginan. Selama seluruh proses pendinginan, struktur rantai molekul yang stabil sedang dibentuk pada antarmuka pipa PE. Pada saat ini, perlu untuk memastikan bahwa alat kelengkapan pipa dan pipa benar-benar tetap, dan segala bentuk rotasi atau gerakan dilarang keras. Bahkan sedikit rotasi dapat merusak sambungan las yang sedang didinginkan dan dipadatkan, mengakibatkan penurunan kekuatan antarmuka dan mempengaruhi daya dukung tekanan dan masa pakai seluruh sistem pipa.

AD Pipa mengingatkan Anda bahwa kualitas sambungan panas-meleleh dari pipa PE berhubungan langsung dengan kualitas seluruh proyek pipa. Beroperasi secara ketat sesuai dengan spesifikasi dan menggenggam simpul kunci "apakah dapat diputar" adalah dasar untuk memastikan bahwa pengelasan kokoh dan sistem aman dan tahan lama. Jika Anda memiliki pertanyaan tentang spesifikasi operasi, disarankan untuk merujuk pada pedoman konstruksi resmi yang disediakan oleh AD Pipeline atau berkonsultasi dengan teknisi profesional untuk memastikan bahwa setiap sambungan yang dilas memenuhi standar dan memungkinkan sistem perpipaan berkinerja terbaik dalam penggunaan jangka panjang.
