"Cara mengukur ketebalan dinding untuk paip beralun dua dinding HDPE

2025-08-19

Belos berdinding dua HDPE ialah paip plastik yang biasa digunakan. Ketebalan dindingnya adalah salah satu penunjuk utama untuk mengukur kualiti produk. Ia berkaitan secara langsung dengan kekakuan gelang, rintangan tekanan dan hayat perkhidmatan paip. Mengukur ketebalan dinding dengan tepat adalah penting untuk memastikan kualiti kejuruteraan dan operasi sistem paip yang selamat. Sebagai jenama terkenal dalam industri, saluran paip AD sentiasa mengutamakan kualiti produk. Berikut ialah pengenalan terperinci kaedah pengukuran untuk ketebalan dinding belos berdinding dua HDPE.

Apabila mengukur ketebalan dinding belos berdinding dua HDPE, alat yang biasa digunakan ialah mikrometer ketebalan dinding atau angkup vernikular. Alat ini mempunyai ketepatan yang tinggi dan boleh memenuhi keperluan pengukuran. Sebelum mengukur, anda perlu memastikan bahawa tapak paip yang diukur adalah bersih, tiada pencemaran minyak, kekotoran atau kerosakan yang jelas, supaya tidak menjejaskan ketepatan keputusan pengukuran. Pada masa yang sama, anda harus membaca manual produk paip dengan teliti untuk memahami keperluan ketebalan dinding standard untuk belos dua dinding HDPE spesifikasi ini untuk perbandingan seterusnya.

Untuk belos dua dinding HDPE, disebabkan ciri strukturnya, perhatian khusus perlu diberikan untuk membezakan antara dinding dalam dan luar apabila mengukur ketebalan dinding. Biasanya, ketebalan dinding merujuk kepada ketebalan dinding nominal paip, iaitu ketebalan purata dinding paip. Apabila menggunakan angkup untuk mengukur, cakar pengukur angkup hendaklah diletakkan dengan lancar pada keratan rentas paip, untuk memastikan bahawa cakar pengukur bersentuhan rapat dengan dinding dalam dan luar paip dan berserenjang dengan paksi paip. Untuk puncak dan bahagian palung belos belos, ukuran harus dibuat secara berasingan, kerana mungkin terdapat perbezaan dalam ketebalan dinding antara kedua-dua bahagian ini dan data perlu direkodkan secara berasingan.

Langkah pengukuran khusus adalah seperti berikut:

Langkah pertama, pilih lokasi pengukuran yang sesuai. Untuk memastikan keterwakilan keputusan pengukuran, beberapa ukuran hendaklah dibuat di lokasi tiub yang berbeza. Secara amnya, sekurang-kurangnya 3 keratan rentas berbeza harus dipilih secara sama rata dalam arah lilitan tiub, dan sekurang-kurangnya 3 titik teragih sama rata dipilih pada setiap keratan rentas untuk pengukuran. Ini boleh mengelakkan ralat pengukuran dengan berkesan disebabkan oleh ketebalan dinding yang tidak sekata yang mungkin berlaku semasa pengeluaran tiub. Langkah kedua, lakukan operasi pengukuran. Tekan kaki pengukur angkup pada bahagian ketebalan dinding tiub, berhati-hati agar tidak terlalu kuat, supaya tidak merosakkan tiub atau mengubah bentuk angkup, menjejaskan ketepatan bacaan. Selepas nombor angkup distabilkan, baca dan rekod data pengukuran. Untuk mikrometer, anda harus membaca skala tetap, kemudian separuh skala boleh alih, dan menganggar.

Langkah 3, pemprosesan data dan pertimbangan. Selepas merekod data semua titik pengukur, kira purata ketebalan dinding bagi setiap keratan rentas dan purata ketebalan dinding bagi keseluruhan paip. Bandingkan purata ketebalan dinding yang dikira dengan julat ketebalan dinding yang dinyatakan dalam piawaian produk untuk menentukan sama ada ketebalan dinding belos berdinding dua HDPE memenuhi keperluan. Jika keputusan pengukuran berada dalam julat piawai, ketebalan dinding tiub itu layak; jika ia melebihi julat piawai, ia perlu diperiksa atau diproses lagi.

Sebagai tambahan kepada pengukuran langsung menggunakan angkup, instrumen pengukur profesional seperti tolok ketebalan ultrasonik boleh digunakan untuk beberapa keadaan khas atau untuk aplikasi yang memerlukan ketepatan pengukuran yang lebih tinggi. Tolok ketebalan ultrasonik mengira ketebalan dinding mengikut masa perambatan gelombang bunyi dalam tiub dengan menghantar dan menerima gelombang ultrasonik. Ia mempunyai kelebihan tidak merosakkan, ketepatan tinggi dan julat ukuran yang luas. Apabila menggunakan tolok ketebalan ultrasonik, instrumen perlu ditentukur terlebih dahulu, kemudian gunakan agen gandingan pada permukaan tiub untuk menghubungi probe dengan permukaan tiub untuk membuat pengukuran.

Semasa proses pengukuran, perkara-perkara berikut juga perlu diberi perhatian: Pertama, persekitaran pengukuran harus kekal kering dan bersih, dan pengukuran dalam persekitaran suhu tinggi, lembap atau gas menghakis harus dielakkan, supaya tidak menjejaskan ketepatan dan hayat perkhidmatan instrumen; Kedua, pengendali harus biasa dengan kaedah penggunaan dan langkah berjaga-jaga alat pengukur, dan beroperasi mengikut prosedur operasi dengan ketat; Ketiga, data pengukuran harus direkodkan dengan teliti dan disimpan dengan betul untuk kebolehkesanan dan analisis kualiti seterusnya.

Secara ringkasnya, mengukur dengan tepat ketebalan dinding belos dua dinding HDPE adalah bahagian penting dalam memastikan kualiti produk. Dengan menggunakan kaedah dan alat pengukuran yang betul, mengikut langkah pengukuran dengan ketat, dan memproses dan menilai data pengukuran secara saintifik dan munasabah, adalah mungkin untuk memastikan ketebalan dinding paip memenuhi keperluan standard dengan berkesan. Paip AD sentiasa komited untuk menyediakan produk paip beralun dua dinding HDPE berkualiti tinggi kepada majoriti pengguna, mengawal ketat setiap pautan dalam proses pengeluaran untuk memastikan kualiti produk yang stabil dan boleh dipercayai. Diharapkan melalui kaedah pengukuran yang diperkenalkan di atas, ia dapat membantu semua orang memahami dan menguasai teknik pengukuran ketebalan dinding paip beralun dua dinding HDPE dengan lebih baik
