Bolehkah tiub PE membeku dan retak?

2025-08-19

Semasa musim sejuk, keretakan saluran paip adalah kebimbangan ramai, terutamanya untuk paip yang digunakan di luar rumah atau dalam persekitaran yang tidak dipanaskan. Sebagai paip plastik yang biasa digunakan, paip PE sering digunakan dalam bidang bekalan air, saliran dan lain-lain, jadi adakah ia akan membeku pada musim sejuk? Sebagai pengeluar paip profesional, paip AD akan menghuraikan masalah ini untuk anda. Paip

PE, iaitu paip polietilena, mempunyai fleksibiliti yang baik dan rintangan hentaman suhu rendah. Ini kerana bahan PE itu sendiri masih boleh mengekalkan tahap keanjalan tertentu pada suhu rendah, tidak seperti sesetengah bahan rapuh (seperti paip PVC atau logam) yang mudah rapuh dan pecah pada suhu rendah. Apabila air di dalam tiub PE membeku, isipadu aising air akan mengembang. Fleksibiliti tiub PE membolehkannya berubah bentuk secara elastik pada tahap tertentu, sekali gus menampan tekanan yang disebabkan oleh pengembangan ais. Jika paip dipasang mengikut spesifikasi, terdapat ruang yang mencukupi untuk pengembangan dan kualiti paip adalah layak, tiub PE tidak akan mudah pecah akibat pembekuan pada musim sejuk.

Walau bagaimanapun, ini tidak bermakna tiub PE tidak akan pernah membeku dalam apa jua keadaan. Jika air dalam tiub PE benar-benar membeku dan tidak ada ruang penimbal semasa proses pembekuan (contohnya, paip tetap mati dan tidak dapat membentuk apa-apa), pengembangan isipadu yang berterusan masih boleh melebihi kekuatan tegangan maksimum bahan tiub PE dan menyebabkan paip retak. Di samping itu, jika paip PE itu sendiri mempunyai kecacatan kualiti, seperti ketulenan bahan mentah yang tidak mencukupi, ketebalan dinding yang tidak sekata, proses pengeluaran yang rosak, dan lain-lain, rintangan hentaman suhu rendah dan fleksibiliti akan sangat berkurangan, dan ia juga lebih terdedah kepada kerosakan di bawah keadaan beku.

Untuk menghalang paip PE daripada membeku pada musim sejuk, pemasangan dan penyelenggaraan yang betul adalah penting. Pertama, apabila paip diletakkan, paip PE harus ditanam di bawah garis beku mengikut keadaan iklim tempatan dan kedalaman pembekuan tanah untuk mengelakkan pendedahan langsung paip kepada persekitaran suhu yang sangat rendah. Untuk bahagian paip yang terdedah kepada luar, seperti meter air, injap dan bahagian paip terbuka jarak dekat, langkah-langkah penebat haba perlu diambil, seperti pembalut kapas penebat haba, memasang lengan penebat, dsb., untuk mengurangkan kehilangan haba dan mengelakkan air daripada membeku di dalam paip. Sebelum musim sejuk tiba, untuk sistem paip yang tidak digunakan buat sementara waktu, air dalam paip harus dikosongkan untuk mengelakkan kerosakan pada saluran paip akibat pengembangan air beku.

Memilih produk paip PE berkualiti tinggi adalah jaminan asas. Sebagai pengeluar paip profesional, paip PE yang dihasilkannya menggunakan bahan mentah berkualiti tinggi dengan ketat, dan menggunakan proses dan peralatan pengeluaran termaju untuk memastikan produk mempunyai fleksibiliti yang sangat baik, rintangan hentaman suhu rendah dan kekuatan struktur keseluruhan. Paip PE telah lulus ujian kualiti yang ketat sebelum meninggalkan kilang dan boleh beroperasi dengan pasti dalam pelbagai persekitaran yang kompleks, termasuk menangani cabaran suhu rendah pada musim sejuk.

Secara ringkasnya, paip PE mempunyai risiko keretakan beku yang agak rendah dalam keadaan biasa, tetapi tidak mutlak. Kuasa pengembangan isipadu aising air adalah sangat besar, dan sukar bagi mana-mana paip untuk menahan sepenuhnya tekanan pengembangan tanpa had. Dengan memilih produk paip PE berkualiti tinggi seperti saluran paip AD dan mengambil langkah pemasangan, penebat dan penyelenggaraan yang saintifik dan munasabah, kemungkinan paip PE membeku pada musim sejuk dapat dikurangkan dengan ketara dan operasi sistem paip yang selamat dan stabil pada musim sejuk
