Quare elige 304 Collum Butt Welding Flange?

1. inferioris sumptus

Materia Unit pretium (Probatio) Service vita Comprehensiva sumptus (10 annis)

316 LABIUM 2.3x 15 annis + 1.2x

304 Collum Butt Welding Flange 1.6x 10 annis + 1.0x

Carbon steel LABIUM 1.0x 2 annis (Rust ultrices) 2.8x

2. structuris commoda design

Superficies accurationis obsignatio: RF superficies asperitas 304 labii intemeratae colli concreti LABIUM 125-250μin Ra est, firmitas obsignatio gasket.

Transitus colli attenuatis: Reducere accentus retrahitur factor per 40% et dilatatur vita lassitudine contracta.

3. Basic corrosio resistentia

Sal imbre test: Non rubigo pro D horis

Chromium-nickel iacuit tutela: Cr contentum ≥18% facit film passivam ad resistendum corrosioni ex aqua, vapore et acido debili (pH>4.5).

Limitatio descriptio: Non apta ambitibus quae chloridi iones 50ppm (ut marinis) continentur, et 316 hoc tempore upgraded oportet.

FAQ

Q1: Quid interest cum 316 LABIUM sumptus?

Responsio: Pretium 304 Colli Butt Welding Flange est 30~35% inferior sub eisdem specificationibus (ob differentiam contenti nickel et molybdeni). Si medium chloridum / acida non continet, magis frugi est 304 eligere.

Q2: Num 304 tibiae foris adhiberi possunt?

Responsio: Humiditas humilis (<60%) RH) diu in sal libero ambitu adhiberi potest; anti-corrosio membranae in locis maritimis/industrialibus requiritur, alioquin intra 2-3 annos contingere potest.
