Apa pancegahan kanggo nggunakake flanges stainless steel?

2023-07-06

1. Kanggo nyegah karat mripat kanggo mripat disebabake dadi panas saka tutup flange, saiki welding ngirim ora gedhe banget, kang kira-kira 20% kurang saka rod welding baja karbon. Arc ngirim ora dawa banget, lan cooling interlayer kudu cepet. Disaranake nggunakake pass welding sing sempit.

2. Nalika nggunakake welding rod, padha kudu tetep garing. Tipe kalsium titanium kudu dikeringake ing suhu 150 ℃ sajrone 1 jam, dene jinis hidrogen sing sithik A kudu dikeringake ing suhu 200-250 ℃ sajrone 1 jam (ora diidini pangatusan bola-bali, yen lapisan bisa retak lan copot) kanggo nyegah rod welding. nutupi saka tancep kanggo lenga lan rereget liyane, supaya dadi ora kanggo nambah isi karbon saka lapisan welding lan mengaruhi kualitas Piece welding.

3. Nalika weldingfitting flange stainless steel, Karbida diendhani amarga pemanasan bola-bali, sing nyuda resistensi korosi lan sifat mekanik.

4. Sawise welding, krom stainless steel flange fittings duwe hardenability luwih gedhe minangka saben flanges standar Amérika, kang rawan kanggo retak. Yen jinis rod welding stainless steel kromium sing padha (G202, G207) digunakake kanggo welding, preheating ndhuwur 300 ℃ lan perawatan cooling alon watara 700 ℃ sawise welding kudu digawa metu. Yen weldment ora bisa ngalami perawatan panas kirim weld, stainless steel flange pipe welding rod (A107, A207) kudu digunakake.

5. Flange baja tahan karat, Kanthi tambahan cocok saka unsur stabil kayata Ti, Nb, Mo, etc. kanggo nambah resistance karat lan weldability, duwe weldability luwih saka kromium stainless steel flanges. Nalika nggunakake jinis padha kromium stainless steel flange welding rod (G302, G307), preheating ndhuwur 200 ℃ lan tempering perawatan watara 800 ℃ sawise welding kudu digawa metu. Yen weldment ora bisa ngalami perawatan panas, rod welding pipe flange stainless steel (A107, A207) kudu digunakake.

6. Fitting flange stainless steellan welding rod kanggo welding flanges duwe resistance karat apik lan resistance oksidasi, lan digunakake digunakake ing kimia, pupuk, Petroleum, lan mesin medical Manufaktur.
