I - M - T - P Random Packing For Mexico 50# SS316L Metal Saddle Rings
1. Metal Saddle Rings Introduction:
Metal saddle ring is composed of ring and saddle shape, with tongue shaped ribs inside.
Metal Saddle Ring is one popular type of column random packing. Compared with Raschig Ring with the same material, it has high flux, high efficiency and low pressure drop. Also Metal Saddle Rings has less resistance, higher flux, higher efficiency, better packing strength and rigidity than Pall Rings. Metal Saddle Ring, also known as Intalox Saddles, I ring, IMTP packing, is the most widely used random packing nowadays.
According to the standard from China Chemistry Industry, HG/T 21554.2-1995, we have got following data sheet.
2. Metal Saddle Rings Size Specification:
| Type | Inner Circle D1 | Outer Circle D2 | Width B1 | Height H1 | Thickness δ |

| 70# | 70±1.2 | 76.5±1.2 | 35.5±1.0 | 75.2±1.2 | 0.6±0.07 |
3. Metal Saddle Rings Geometric Parameters
| Type | Size (mm) | Packing No. n (pc/m3) | Packing density γp (kg/m3) | Specific Area a (m2/m3) | Voidage ε (m3/m3) | Dry Packing Factor a/ε3 (m-1) |
| 25# | 25*15*0.3 | 87720 | 188 | 171 | 0.976 | 184 |
| 38# | 38*16.5*0.4 | 38160 | 181 | 123 | 0.977 | 132 |

4. Metal Saddle Ring Packing Bed:
Metal saddle ring packed bed has a large void fraction, and most of the packing is circular liquid channel, which reduces the resistance of gas passing through the bed, also reduces the radial diffusion coefficient of liquid flowing downward.
Metal saddle ring is widely applied in drying tower, absorption tower, cooling tower, washing tower, wet scrubber tower, Regeneration tower, etc. Covering the industries like Chemical, Metallurgical, Gas and Environmental Protection.
5. Metal Saddle Ring More Options:
There are more types in some oversea factories, here we try to list some of the reference data, too.
| Packing Size (mm) | Void Fraction (%) | Bulk Weight (kg/m3) |
| 15 | 96 | 283 |
| 25 | 97 | 224 |
| 40 | 98 | 153 |
| 50 | 98 | 166 |
| 60 | 98 | 137 |
| 70 | 98 | 141 |
6. Metal Saddle Ring Side View:
We can see that the upper arc is an elliptic curve and the lower arc is a semicircle curve. Though it looks complex in the self-structure and shape, it is made of a single square piece of metal sheet. So it will be easy to calculate the specific area of this kind of packing, if we know the bulk packing number of a cubic meter.
With experiences and technologies of random packing in Hualai, we are expecting to be helpful in your project!
