Deskripsi Produk
Instruksi teknis pipa baja pelapis 3 lapisan
Struktur pipa baja lapisan 3PE
Tiga lapisan PE PE PE Anti-korosif Pipa Baja Melakukan standar GB/T23257-2009 dan DIN30670.
Struktur: Pipa baja bagian dalam, lapisan bubuk epoksi, lapisan tengah perekat, lapisan luar polietilen kepadatan tinggi
Keuntungan dari pipa antiseptik
1. Resistensi dampak sempurna, resistensi gesekan, ketahanan guncangan
2. Resistensi Garam Alkali Asam Tinggi
3. Resistensi Kocok Listrik Tinggi
4. Tingkat air yang mengalir rendah
5. Waktu Penggunaan Lama
Proses pembuatan lapisan 3PE
Proses produksi
Inspeksi Pipa Baja → Pipa Baja Pra-pemanasan → Pipa baja-Blasting → Inspeksi Pola Jangkar/Inspeksi Kebersihan → Medium Pipa Baja → Pemanasan Frekuensi → Penyemprotan Bubuk Epoksi → Pelapisan Perekat → Pendingin Air Pembungkus Polyethylene hingga 60ºC Di Bawah → Percikan Listrik Online → Perawatan Akhir Pipa → Inspeksi Produk jadi → Penandaan Produk → Sticking Sertifikasi → Di Penyimpanan
