3 Lapisan PE Lapisan Teknikal Pipa Keluli
Struktur paip keluli salutan 3pe
Tiga lapisan PE salutan paip keluli anti-korosif menjalankan standard GB/T23257-2009 dan DIN30670.
Struktur: paip keluli dalaman, salutan serbuk epoksi, lapisan tengah pelekat, lapisan luar polietilena ketumpatan tinggi
Kelebihan paip antiseptik
1. Rintangan impak yang sempurna, rintangan geseran, rintangan kejutan
2. Rintangan garam alkali asid tinggi
3. Rintangan kejutan elektrik yang tinggi
4. Kadar air yang rendah
5. Masa Penggunaan Long
Proses pembuatan salutan 3pe
Proses pengeluaran
Pemeriksaan Paip Keluli → Pipa Keluli Pra-Pemanasan → Pipa Keluli Pukulan-letupan → Pemeriksaan Corak Corak/Pemeriksaan Kebersihan → Medium Pipa Keluli → Pemanasan Kekerapan → Serbuk Epoxy Spraying → Salutan Pelekat → Polyethylene Wrapping-Air Penyejukan hingga 60ºC Di Bawah → Rawatan Akhir Paip → Pemeriksaan Produk Selesai → Penandaan Produk → Persijilan Melekat → Dalam Penyimpanan
