Industries and Applications We Supply
| Industry | Applications |
|---|---|
Oil Refining |
The Petron Corporation refinery at Limay, Bataan processes 180,000 bpd of crude oil through atmospheric and vacuum distillation, catalytic reforming, and hydroprocessing units, consuming thousands of carbon steel and alloy steel flanges across its extensive piping systems. Werner Flanges supplies ASTM A105 weld neck and blind flanges in Class 300# and 600# for refinery maintenance and project requirements, with delivery to Bataan via Manila Port or direct sea freight to Bataan provincial ports.
Petroleum product import terminals at Pandacan (Manila), Cavite, and Cebu City require carbon steel flanges for jetty piping, storage tank nozzles, and product transfer systems. These terminals handle gasoline, diesel, jet fuel, and LPG, with piping specifications typically following PNS (Philippine National Standards) or ASME B31.4 pipeline codes. |
Mining & Mineral Processing |
The Philippines holds significant deposits of nickel, copper, gold, and chromite, with major mining operations at Surigao del Norte (Nickel Asia), Palawan, and the Caraga region. Mineral processing plants consume industrial flanges in slurry handling systems, leaching circuits, and process water treatment. The acidic and abrasive nature of mining process fluids often requires duplex stainless steel or rubber-lined flanges for corrosion and erosion resistance.
Werner Flanges supplies duplex stainless steel (A182 F51) and carbon steel flanges with appropriate coatings or linings for Philippine mining and mineral processing applications, providing material selection guidance based on specific fluid chemistry and operating conditions. |
Water & Sanitation Infrastructure |
Metro Manila’s water utility sector — served by Maynilad Water Services (West Zone) and Manila Water Company (East Zone) — is undergoing major capacity expansion to address intermittent supply issues affecting millions of consumers. New water treatment plants, reservoir expansion, transmission main upgrades, and pressure management systems all incorporate industrial flanges in carbon steel and ductile iron for pump stations, valve chambers, and pipeline connections.
Provincial water districts across Luzon, Visayas, and Mindanao are implementing similar development programs under the National Water Resources Board and DILG oversight. Werner Flanges supplies Class 150# carbon steel slip-on and weld neck flanges for Philippine water infrastructure, with competitive pricing for government and utility procurement processes. |
Power Generation |
The Philippines operates over 25 GW of installed power generation capacity, with major coal-fired plants at Sual (Pangasinan), Calaca (Batangas), and Masinloc (Zambales), gas-fired facilities at Batangas, and growing renewable capacity. These plants consume carbon steel flanges throughout boiler feed systems, steam distribution, cooling water circuits, and fuel handling infrastructure.
New power plant construction — including additional coal capacity under energy security programs and the rapid expansion of solar and wind facilities requiring balance-of-plant piping — drives ongoing procurement demand. Werner Flanges supplies flanges for power plant construction and maintenance across the Philippine archipelago, with delivery logistics adapted to island locations via inter-island shipping connections. |

- q4: can you supply flanges meeting classification society requirements for philippine shipyards?
- yes. werner flanges manufactures carbon steel and stainless steel flanges with material certifications and manufacturing procedures compatible with major classification society requirements including dnv, lloyd’s register, bureau veritas, and abs. classification society witnessing of tests and inspection can be arranged at our manufacturing facility upon request. we regularly supply flanges for marine applications and understand shipyard specification requirements.
- q5: do you offer flanges to pns (philippine national standards)?
- werner flanges primarily manufactures to asme b16.5, asme b16.47, and mss sp-44 international standards, which are the most widely used flange standards in philippine industrial projects and are accepted across all philippine industrial sectors. we can also supply flanges to din, jis, bs, and other international standards. where pns specifications reference asme or international standards (which is common for pressure piping components), our products naturally satisfy these requirements. please provide your specific pns specification references for confirmation.
- q6: what is the minimum order quantity for supply to the philippines?
- werner flanges accepts orders of all sizes, from single critical flanges needed for emergency maintenance to full project procurement packages covering thousands of pieces. there are no minimum order quantities, though larger orders benefit from volume pricing and improved economics per unit on sea freight costs. for very small quantities, air freight may be the most practical delivery option despite higher per-unit freight cost.
