NEO MAKİNA ve MÜHENDİSLİK A.Ş. manufactures and installs underground and above-ground site tanks for on-site storage of fuels, chemicals, water and process liquids. Single or double-wall tanks from 5 m³ to 5,000 m³ for industrial plants, fuel stations, construction sites, generator and boiler rooms are designed to EN 12285, API 650 and API 620, leak-tested and commissioned turnkey.
Underground Site Tanks
- Use: Fuel stations, in-plant refuelling, generator fuel storage, waste-oil and chemical collection.
- Design: Horizontal cylindrical, single or double wall (EN 12285-1); interstitial leak monitoring (vacuum or liquid).
- Corrosion protection: Epoxy/polyurethane external coating after blasting (Sa 2½), cathodic protection where required; GRP outer-wall option.
- Capacity: 5 – 100 m³; compartmented (multi-product) design.
- Fittings: Manway, level gauging, overfill prevention valve, vent, fill and suction lines.
Above-Ground Site Tanks
- Use: Plant fuel storage, boiler-room fuel-oil tanks, water and fire-water tanks, chemical and oil stock tanks.
- Design: Horizontal cylindrical (on legs or saddles) or vertical cylindrical (API 650 / API 620 based); cone, dome or open roof.
- Double-wall above-ground tanks: Integral secondary containment without a bund; leak-sensor monitoring.
- Capacity: 5 – 5,000 m³; for larger tank farms see API 650 Storage Tanks.
- Options: Heating coil (fuel oil, bitumen), insulation and cladding, agitator, internal floating roof (for evaporation loss).
Materials and Fabrication
- Carbon steel (S235JR / P265GH), stainless steel (AISI 304/316L) or special alloys.
- Certified welders (EN ISO 9606), qualified WPS/PQR procedures; radiographic or ultrasonic inspection.
- Hydrostatic and vacuum leak tests; coating thickness and holiday tests.
- Complete shop fabrication or field erection for large diameters.
Typical Application Range
- Capacity: 5 – 5,000 m³ (underground 5–100 m³)
- Products: diesel, petrol, fuel oil, biodiesel, lubricants, AdBlue, chemicals, water, fire water
- Standards: EN 12285-1/2, API 650, API 620, EN 14015, ATEX (Ex equipment)
- Scope: tank, piping, pump and filling unit, level and leak monitoring, earthing, site installation
The NEO MAKİNA Difference
Tank selection is based on stored product, capacity, site conditions and regulatory requirements. Structural calculation, foundation/saddle design, piping and automation are engineered from a single source. Technical support for permitting, installation, testing and commissioning are included.
Frequently Asked Questions
Underground or above-ground tank?
Space constraints and fire-safety distances decide. Above-ground tanks are cheaper and easier to maintain; underground tanks save space and are unaffected by temperature swings.
Is a double wall mandatory?
At fuel stations and sites with groundwater risk, double wall and leak monitoring are required by regulation; above ground, a double wall removes the need for a concrete bund.
What is the delivery time?
3–6 weeks for standard horizontal tanks; 2–5 months for large vertical tanks depending on capacity.
