Stainless Steel Floater Round Magnetic Floating Ball

Stainless Steel Floater Round Magnetic Floating Ball are ideal for use under higher pressure and at correspondingly high temperatures in water or corrosive liquids. The high strength of stainless steel provides an extremely versatile and durable round float balls. We offer many diameters and wall thicknesses to suit your needs.

All spherical or oblong floats are built by welding two shells together. The welding process is critical for the strength and durability of the float. xukang has developed a weld that provides a smoothly finished seam, hardly distinguishable from the rest of the float surface. The weld is uniformly strong and ductile.

Material, Temperature & Pressure Selection Guide for Magnetic Floats (Magnetic Buoys)

1. Common Float Materials & Parameter Range

(1) 304 Stainless Steel Float

Temperature: -20 ~ 200 ℃
Pressure: PN16 / PN25 / PN40
Medium: Clean water, light oil, low-corrosion neutral liquids
Feature: Low cost, standard general model

(2) 316L Stainless Steel Float

Temperature: -30 ~ 250 ℃
Pressure: PN16 ~ PN100
Medium: Weak acid, weak alkali, chemical solvent, sewage
Feature: Better corrosion resistance than 304

(3) Titanium Alloy Float

Temperature: -40 ~ 300 ℃
Pressure: PN25 ~ PN160 (ultra-high pressure)
Medium: Strong oxidizing acid, brine, chloride medium
Feature: Excellent anti-corrosion, for severe chemical working conditions

(4) PTFE Lined Float / All-PTFE Float

Temperature: -20 ~ 180 ℃
Pressure: PN10 ~ PN25
Medium: Strong acid, strong alkali, highly corrosive chemicals
Limitation: Cannot bear ultra-high pressure; easy deformation above 180℃

(5) High-Temp Alloy (Hastelloy/C276) Float

Temperature: -40 ~ 350 ℃
Pressure: PN40 ~ PN160
Medium: Strong corrosive high-temperature medium, hydrogenation reactor
Feature: Super high temp & corrosion resistance for petrochemical high-pressure reactors

2. Temperature Selection Rules

Medium temperature ≤200℃: Choose 304 / 316L standard float
200~300℃ high temp oil, steam: 316L or titanium float
300~350℃ ultra-high temp reactor: Hastelloy alloy float
Strong corrosive high temp medium: PTFE lined 316L float (≤180℃)

3. Pressure Selection Rules

Normal pressure tank (PN10/PN16): 304/316L thin-wall float
High-pressure boiler, hydrogenation equipment (PN40~PN100): Thick-wall 316L / titanium float
Ultra-high pressure synthesis vessel (PN160+): Solid thick-wall Hastelloy or titanium float
PTFE float only for low pressure ≤PN25, forbidden for high pressure

4. Quick Selection Logic

Confirm medium corrosivity → pick float material first
Confirm medium working temperature → filter temp-resistant grade
Confirm system nominal pressure → select wall thickness & pressure rating
Special working condition (cryogenic, easy crystallization, viscous) match customized density float

Short English Version

Magnetic Float Selection (Material, Temp & Pressure)

304 SS: -20~200℃, PN16-PN40, neutral clean oil/water
316L SS: -30~250℃, PN16-PN100, weak acid/alkali solvent
Titanium: -40~300℃, PN25-PN160, brine & oxidizing liquid
PTFE lined: -20~180℃, PN10-PN25, strong acid/alkali
Hastelloy C276: -40~350℃, PN40-PN160, high temp & strong corrosion

Selection order: Corrosion medium → working temperature → system pressure.
