A516Gr70+316L Plak asye rekouvèr aplikasyon
Endistri chimik:
Tank Depo Asid: Reziste 5-20% asid silfirik ak klori-chaje dlo ize.
Réacteurs: Manyen sentèz òganik anba presyon ak tanperati ki wo.
Lwil oliv ak gaz:
Inite Hydrocracking: A516Gr70 bay entegrite estriktirèl, pandan y ap 316L reziste H₂S ak korozyon klori.
Pipelines anba lanmè: reziste dlo lanmè ak gwo -likid idrokarbone presyon.
Jeni Marin:
Plant Desalin: Reziste dlo salm ak dezenfektan ki baze sou klò-.
Tank bato: Sere gaz oswa dlo lanmè ak korozyon minimòm.
Manje ak famasetik:
Ekipman pwosesis: Satisfè estanda FDA pou ijyèn (Ra mwens pase oswa egal a 1.6μm) ak reziste ajan netwayaj.

Inovasyon Teknolojik Anba Kondisyon Travay Espesyal
Soude nan anviwònman ki ba-tanperati
Lè tanperati anbyen se<0°C, additional preheating to 200–250°C is required, and the "multi-layer and multi-pass welding" method should be adopted, with the interpass temperature maintained at 150–200°C.
Post-chofaj (250-300 degre, kenbe pou 1 èdtan) ta dwe fèt imedyatman apre soude pou akselere difizyon idwojèn.
Pwoteksyon kont medya ki trè korozivite
Transition Layer Upgrade: In environments with Cl⁻ concentration >1000ppm, li rekòmande pou itilize ER NiCrMo-3 (Inconel 625) pou kouch tranzisyon an, ki gen 9-10% Mo epi ki gen yon Pitting Resistance Ekivalan Nimewo (PREN) ki pi gran pase oswa egal a 40.
Sifas Kouch: Apre soude, sifas kouch nan CLADDING se flite ak yon kouch epoksidik résine / alumina konpoze (epesè 150-200μm). Tan rezistans korozyon nan tès espre sèl la (ASTM B117) depase 5000 èdtan.
Pou veso presyon sanitè nan endistri pharmaceutique/manje (egzanp, tank depo dwòg esteril, ekipman pwosesis letye), nou bay Q345B+304L asye rekouvèr oswa Q235B+304 asye revèti ki satisfè estanda TSG 21 ak manje-. Si ou bezwen konnen kondisyon irrégularité sifas, soudabilite ak ekipman sanitè, oswa kalkile depans pwosesis pou kavite enteryè Customized, voye yon ankèt pou konsiltasyon pwofesyonèl ak dokiman sètifikasyon.
