Apakah ada perbedaan daya dukung tekanan air dari pipa PE dengan diameter yang berbeda?

2025-08-18

Dalam penerapan pipa PE, banyak orang akan khawatir tentang sebuah pertanyaan: Apakah ada perbedaan daya dukung tekanan air dari pipa PE dengan diameter yang berbeda? Jawabannya ya, tetapi perbedaan ini tidak hanya ditentukan oleh ukuran diameter, tetapi oleh kombinasi faktor.

Pertama-tama, kita perlu mengklarifikasi bahwa daya dukung tekanan air dari pipa PE terutama dinyatakan oleh tekanan nominalnya (PN), yang merupakan tekanan kerja maksimum yang dapat diangkut pipa dengan aman pada suhu kamar. Secara umum, tekanan nominal pipa PE memiliki beberapa tingkatan, seperti PN1.0, PN1.6, PN2.0, dll. Semakin besar nilainya, semakin kuat daya dukung tekanannya.

Jadi, apa hubungan antara diameter dan tekanan nominalnya? Dalam keadaan normal, di bawah kondisi grade material dan ketebalan dinding yang sama, tidak ada korelasi positif atau negatif langsung antara diameter pipa PE dan daya dukung tekanan air. Artinya, bukan karena semakin besar diameternya, semakin rendah daya dukung tekanan, atau semakin kecil diameternya, semakin tinggi daya dukung tekanannya. Misalnya, pipa PE yang sama dengan kelas PN1.6, pipa berdiameter kecil dn20 dan pipa berdiameter besar dn315, tekanan nominalnya sama, dan batas atas tekanan air yang dapat bertahan secara teori adalah sama.

Tetapi mengapa diameter pipa PE yang berbeda merasakan daya dukung tekanan yang berbeda dalam aplikasi praktis? Ini terutama karena dalam desain dan produksi, diameter pipa PE yang berbeda akan cocok dengan ketebalan dinding dan tekanan nominal yang sesuai sesuai dengan skenario aplikasi umum mereka. Misalnya, pipa PE berdiameter kecil sering digunakan dalam pipa cabang dengan persyaratan tekanan yang relatif tinggi seperti pasokan air rumah tangga dan irigasi kecil, dan dapat memilih spesifikasi tekanan nominal yang lebih tinggi; sedangkan pipa PE berdiameter besar lebih banyak digunakan dalam pipa batang pasokan air kota, limbah, dll. Tekanan desain akan ditentukan secara komprehensif sesuai dengan faktor-faktor seperti jarak pengangkutan dan laju aliran, tidak harus lebih rendah dari pipa berdiameter kecil, dan juga dapat memilih nilai PN yang berbeda karena kebutuhan yang berbeda.

Faktor kunci yang mempengaruhi toleransi tekanan air dari pipa PE sebenarnya adalah sifat dari bahan itu sendiri (seperti kekuatan tingkat bahan yang berbeda seperti PE80 dan PE100), ketebalan dinding pipa, dan proses produksi. Semakin tinggi kadar material, semakin tebal dinding pipa, semakin kuat kekuatan struktural dan ketahanan tekanan internal pipa, dan semakin besar tekanan air yang dapat ditahannya. Bahkan untuk pipa PE dengan diameter yang sama, jika ketebalan dinding berbeda, tekanan nominalnya akan berbeda secara signifikan.

Oleh karena itu, ketika memilih pipa PE, tidak mungkin menilai daya dukung tekanan airnya hanya berdasarkan diameter, tetapi harus fokus pada tekanan nominal (nilai PN), kadar material dan ketebalan dinding pipa. Produk pipa PE yang memenuhi persyaratan desain harus dipilih sesuai dengan tekanan kerja aktual, karakteristik sedang dan lingkungan peletakan dan faktor lainnya untuk memastikan pengoperasian sistem pipa yang aman dan stabil. Jika ada keraguan tentang pemilihan spesifik, disarankan untuk berkonsultasi dengan teknisi pipa profesional atau merujuk pada standar produk yang relevan dan spesifikasi desain.
