Sedikit kebocoran pada pipa PE tua, cara memperbaikinya secara efektif

2025-08-18

Di bidang pasokan dan drainase air bangunan, teknik kota dan irigasi pertanian, pipa PE telah banyak digunakan karena ketahanan korosi, fleksibilitas yang baik dan karakteristik lainnya. Namun, dengan meningkatnya masa pakai, pipa PE tua mungkin mengalami sedikit kebocoran karena penuaan material, tekanan eksternal atau kerusakan kecil. Jika tidak ditangani tepat waktu, tidak hanya akan menyebabkan pemborosan sumber daya air, tetapi juga dapat menyebabkan kerusakan pipa yang lebih serius. Berikut ini memperkenalkan metode perbaikan yang efektif untuk kebocoran kecil pipa PE lama untuk Anda.

Pertama-tama, sebelum pekerjaan perbaikan apa pun, perlu melakukan persiapan penuh. Tugas pertama adalah menutup katup hulu dari titik kebocoran, memastikan bahwa air dihentikan di pipa di area perbaikan, dan mengosongkan sisa air di pipa untuk menjaga lingkungan kerja yang kering. Selanjutnya, bersihkan permukaan pipa dengan hati-hati di sekitar titik kebocoran, dan gunakan lap atau amplas untuk menghilangkan minyak, karat, tanah, dan lapisan oksida yang lepas, sehingga permukaan pipa bersih dan kasar, yang dapat secara efektif meningkatkan gaya ikatan antara bahan perbaikan dan pipa. Pada saat yang sama, tandai lokasi kebocoran yang tepat, sehingga operasi perbaikan selanjutnya lebih akurat.

Untuk sedikit kebocoran pipa PE lama, metode perbaikan pita karet (atau kartu pipa karet) adalah pilihan yang mudah dan andal. Pilih pita perbaikan karet yang sesuai dengan diameter pipa, yang biasanya lengket di bagian dalam atau dapat diperbaiki dengan alat pengikat. Bungkus pita perbaikan dengan erat di sekitar titik kebocoran untuk memastikan bahwa itu benar-benar menutupi titik kebocoran dan area sekitarnya setidaknya 5 cm. Jika pita perbaikan dengan penjepit logam digunakan, baut pada penjepit perlu dikencangkan secara merata dengan kunci pas, sehingga pita karet terpasang erat ke permukaan pipa untuk membentuk segel yang efektif. Metode ini cocok untuk sistem perpipaan dengan tekanan rendah dan dapat dengan cepat menghentikan kebocoran air.

Metode lain yang umum digunakan adalah metode perbaikan pita tahan air berperekat sendiri. Pita umumnya terbuat dari karet butil atau bahan elastis berkinerja tinggi lainnya dan memiliki daya rekat dan ketahanan air yang sangat baik. Pada permukaan pipa yang bersih dan kering, mulai dari sisi titik kebocoran air, bungkus pita dengan erat dengan cara semi-tumpang tindih. Saat membungkus, gaya tarik tertentu perlu diterapkan untuk memastikan bahwa tidak ada gelembung atau lipatan antara pita dan pipa dan lapisan pita. Jumlah lapisan penggulungan dianjurkan tidak kurang dari 5-5 lapisan. Ujung lapisan terakhir dapat diperbaiki dengan pita perekat itu sendiri atau diikat dengan ikatan kabel untuk memastikan kekencangan perbaikan.

Setelah perbaikan selesai, jangan segera mengembalikan pasokan air. Periksa apakah bagian perbaikan terpasang dengan kuat dan segelnya rapat. Setelah memastikan bahwa itu benar, perlahan buka katup untuk mengamati apakah ada kebocoran di tempat perbaikan. Pada tahap awal setelah air dilewatkan, perlu untuk terus memperhatikan selama jangka waktu tertentu untuk memastikan efek perbaikan yang stabil. Pada saat yang sama, perhatian harus diberikan untuk menghindari benturan parah atau tekanan berat pada pipa yang diperbaiki untuk mencegah lapisan perbaikan jatuh atau pipa rusak lagi.

Perlu dicatat bahwa metode di atas terutama cocok untuk kebocoran pipa kecil dan lokal. Jika kebocoran pipa serius, seperti kerusakan skala besar, retakan panjang atau penipisan serius pada dinding pipa, disarankan untuk menghubungi personel pemeliharaan pipa profesional tepat waktu untuk evaluasi. Jika perlu, pipa harus diganti untuk memastikan operasi sistem pipa yang aman dalam jangka panjang. Perbaikan yang tepat waktu dan efektif tidak hanya dapat menghemat biaya perawatan, tetapi juga menghindari serangkaian bahaya keselamatan yang disebabkan oleh kebocoran air.
