A PP/PPH horizontal storage tank carries the same corrosion resistance as the vertical type in a low-profile, saddle-mounted form — for transport, dosing and height-limited installs. Custom volume and nozzles.
PP/PPH Horizontal Storage Tank
A PP/PPH horizontal storage tank uses the same welded polypropylene / PPH material as the vertical type, arranged as a horizontal cylinder on saddle or cradle supports. The low center of gravity and small footprint make it the right choice where headroom is limited, for mobile/transport duty, or for day-tanks and dosing stations. “PPH” is the polypropylene homopolymer grade with higher rigidity and service temperature than random-copolymer PP.
Construction
- Horizontal cylindrical shell on saddle/cradle supports; anti-roll and lifting lugs as required.
- Manways, level and agitation options; transport versions often baffled.
- Larger units use PP-FRP or PP-lined-steel for shell stiffness over long spans.
Chemical Resistance
Identical to the vertical PP/PPH family: non-oxidizing acids (dilute HCl, H2SO4 to moderate concentration, H3PO4), alkalis (NaOH, KOH), brines, demin water and many organics. Avoid strong oxidizers, exceedance of temperature limit, and verify compatibility for chlorinated/aromatic solvent service.
Vertical vs Horizontal
| Geometry | Use case |
|---|---|
| Vertical | Static bulk storage, space-efficient footprint, larger single volumes |
| Horizontal (this page) | Transport, low-clearance / underground-ish installs, dosing & day tanks |
Where It Fits (full range)
| Tank type | Best for |
|---|---|
| PP/PPH vertical | Static bulk storage of non-oxidizing acids & alkalis; small-to-mid volume |
| PP/PPH horizontal (this page / family) | Same media, but low-profile / transport / dosing / height-limited installs |
| FRP | Large-volume water, wastewater, mild chemicals; lightweight; solvent-capable (resin-dependent) |
| Stainless steel | Hygienic food/pharma/water service; high temp & pressure; NOT strong acids |
Typical Applications
- Road/rail transport of compatible chemicals
- Mobile and dosing tanks, day tanks
- Low-clearance or height-restricted installations
- Interim storage of non-oxidizing process liquids
Customization
Each tank is custom-engineered to your duty: volume, diameter/length, wall build-up, saddle design, nozzles and accessories are specified per your media and mounting. Share capacity, liquid, concentration and temperature and we size it.
