High-Strength HDPE Modular 16-Sided Two-Piece Manhole Well | Fuel Station and Industrial Fluid Pipeline Management
The RFMOW-1150 series is a two-piece 16-sided HDPE manhole well specifically designed for fuel stations and industrial fluid pipeline systems. Its two-piece design allows separate installation of the upper and lower sections, making it ideal for limited-space or complex piping environments. High-strength HDPE material provides excellent chemical resistance and sealing performance, ensuring long service life and stable performance even under repeated use or harsh conditions.
Globally, this manhole well is known by various names depending on industry conventions and regional terminology. In Brazil, it is called “Poço operacional modular HDPE de 16 faces”; in Argentina, “Pozo operativo HDPE de 16 lados modular”; and in Colombia, “Pozo de operación HDPE modular de 16 caras”. In other regions, it is commonly referred to as an HDPE manhole well, modular tank sump, or 16-sided modular access well.
The modular design not only optimizes transportation and on-site adjustments but also allows for partial maintenance and replacement without complete disassembly. The inward flange installation ensures that the well body is securely seated within the ground opening while maintaining a tight seal with the surrounding soil and upper cover components. This protects underground pipelines, valves, and vapor recovery components from rainwater, groundwater, and environmental corrosion.
Technical Specifications and Customization Options
The RFMOW-1150 is made of high-density polyethylene (HDPE) and uses an inward flange installation method. The flange bolt hole center-to-center distance is 1150 mm, adjustable as needed. Standard bolt holes include 32 holes of 13 mm diameter, customizable on request. The body outer diameter is 1420 mm and inner diameter 1400 mm. The neck outer diameter is 850 mm, inner diameter 830 mm. The pipe connection section height is 580 mm, with a total height of 1300 mm. The 16-sided regular polygon shape provides structural integrity, and the wall thickness is 10 mm, customizable based on project requirements. Color options include green, white, black, and grey, with custom colors and logo engraving available.
Core Advantages and Applications
This manhole well offers multiple advantages for fuel stations and industrial fluid systems. Its modular structure enables flexible installation in complex or space-constrained environments. HDPE provides exceptional durability and chemical resistance, maintaining stability even under long-term use and harsh conditions. The inward flange ensures tight sealing, preventing rainwater, groundwater, or contaminants from entering the well while protecting pipelines, valves, and vapor recovery systems. Modular design also facilitates partial maintenance and replacement, improving construction efficiency and minimizing downtime. It is suitable for underground fuel pipelines, chemical pipelines, industrial fluid systems, and temporary or mobile pipeline setups, meeting both international and local project standards.
The RFMOW-1150 series manhole well provides secure, reliable underground pipeline protection while offering modular design and customization options for flexible installation and long-term maintenance. Whether in Brazil, Argentina, Colombia, or other countries, this 16-sided two-piece HDPE manhole well adapts to various project requirements and provides an efficient solution for fuel and industrial fluid management.
