Crumpler Plastic Pipe Inc. (CPPP) products
CPP - Corrosion Resistant HDPE Gravity Drain Pipes
As urban, industrial, and agricultural development advances, there is an increased emergence of impervious surfaces like roads, parking lots, and airports, which contribute to more polluted outlet streams. These developments compromise nature's soil-plant filtering ability, necessitating effective stormwater and wastewater management solutions. CPP addresses these requirements with its corrosion resistant, gravity drain pipe systems made of high-density polyethylene (HDPE). These systems are designed to meet Best Management Practice (BMP) standards for both waste and stormwater treatment applications. CPP offers single wall and dual wall smooth core HDPE corrugated pipes, which are suitable for various applications like culvert storm sewers, wastewater treatment, commercial landscaping, and agricultural drainage. Their dual wall smooth core/n-10 pipes are ideal for high-flow capacity situations, minimizing maintenance costs due to their anti-adhesive properties. The HDPE material also provides excellent resistance to chemical reactions and abrasion, making CPP pipes a reliable choice for fluid transport in chemically active conditions. Engineers and contractors can now access the comprehensive Corrugated Plastic Pipe Handbook for detailed technical information and installation guidelines.CPP - Bell & Spigot Couplers with O Ring Gasket
CPP Inc. offers Bell and Spigot Couplers equipped with O Ring Gaskets that provide a water seal, compliant with ASTM-F-477 standards. These couplers are designed to meet the 13 psi pre-installation gravity flow requirements as specified by ASTM-D-3212. Although these lab tests do not directly translate to field performance, they are essential for evaluating the joint's capabilities under ideal conditions. For in-field performance tests, inspectors may refer to ASTM-F-2487 (06), a specification tailored for polyethylene corrugated pipe joint performance. CPP pipes sized from 12 to 24 inches meet the 13 psi requirement with one ASTM-F-477 O Ring Gasket, while sizes from 30 to 48 inches incorporate an additional stainless steel band for enhanced performance. Installers must ensure proper soil compaction around the pipes according to ASTM-D-2321 and the PPI-CPPA guide to prevent deflection stresses exceeding 5%. Additional care is required in areas prone to soil-moisture changes, necessitating gravel pack load-bearing envelopes within a filter wrap for stability. The flexibility of CPP pipes accommodates minor soil settling, reducing joint misalignment issues. In challenging soil conditions or fluctuating water tables, engineers should consider specifying a CPP mastic wrap coupler to prevent long-term leaks and sinkhole formations. Proper lubrication of the O Ring and bell coupler with a non-petroleum, biodegradable lubricant is crucial for secure joint assembly.
CPP - Corrugated Pipes and Hand Made Fittings
The lightweight nature of CPP’s corrugated pipes offers a significant reduction in installation expenses due to the reduced need for large crews and heavy excavation machinery. Additionally, CPP’s custom hand-made fitting products further reduce installation costs in drainage systems. CPP provides large and small catch basins, and can incorporate cut-off gate valves into pipe systems as necessary. Their engineered fittings are versatile and can be customized for specific project requirements including radon gas relief, electrical conduit, tubular concrete forms, relining corrosion-worn pipes, and low-pressure industrial vacuum hoses.
CPP - Retention/Detention Systems
CPP, Inc. provides underground stormwater storage products that are essential for developers and commercial property owners looking to save land space for additional building areas. These stormwater BMPs are strategically placed underneath parking lots, roadways, athletic fields, and open space areas to store volumes of stormwater runoff. This stored water can then be reused, discharged to public storm sewers, or infiltrated into the soil to recharge local aquifers. To protect these systems from trash and sediment accumulation, CPP, Inc. recommends the use of Trash Guard®, a durable plastic screen designed to remove unsightly trash and sediments laced with regulated metals, nitrogen, and phosphorus from the stormwater flow. This ensures that CPP underground detention systems maintain functionality and longevity. The system components, including CPP special fabricated manifold T’s and plastic culverts, perform under traffic-bearing pavement, facilitating faster and more efficient construction schedules. CPP offers a range of catch basin inlets to complement these detention-retention systems.
CPP - No-Rock Fabric Wrapped Septic Pipe
CPP's No-Rock Septic-Leachate drainpipe systems have been effectively employed since 1985 in soil conditions suitable for conventional 4-inch drainpipes with gravel. These systems offer a significant advantage by eliminating the need for rock, particularly in areas where quality rock is scarce or expensive, and in regions with challenging topography that complicate traditional septic system installation. The CPP No-Rock systems save trees and preserve soil profiles, which enhances septic sewage treatment. These systems are widely used in the clay areas of North Carolina, West Virginia, Georgia, Kentucky, Tennessee, and Alabama. CPP No-Rock systems streamline inspections, as the main points to check are the drain holes' positioning and pipe levels. Large diameter CPP Gravelless systems utilize a specialized filter wrap, facilitating gravel-free installations. This is beneficial in areas with restricted rock supplies or difficult lot shapes. ASTM-F-481 specifications should be consulted before installation, and compatibility with local regulations should be verified. While suitable for conventional trench systems, these pipes should not replace bed systems or be used in fill material. They are intended for domestic sewage applications and not for grease or oil-heavy environments. The 8-inch pipe is equivalent to a 2-foot wide trench, while the 10-inch pipe corresponds to a 2.5-foot wide trench. Proper installation standards and trench specifications must be followed, including trench width, depth, and line spacing.
CPP - Catch Basins, Manholes, & In-Line Inlet Drains
CPP Corporation highlights the importance of proper connection points in buried pipe systems, focusing on components like catch basins, manholes, drain basins, and inlet drains. Historical issues at these junctions, irrespective of materials, emphasize the necessity of precautions, especially where traffic or soil drag-down is expected, or watertight joints are required. For surface constructions, poured concrete around connection joints and fittings is recommended to ensure durability. Field-fabricated structures can utilize CPP-fabricated or machine-molded fittings, though attention must be given to the correct orientation and backfill procedures to maintain the integrity of the installation. The emphasis on precision in connection and joint handling encapsulates the core of CPP`s installation guidelines to mitigate corrosion and enhance the lifespan of drainage systems.
CPP - Smooth-Core/n-10 Collector Inlet Headwall
The CPP Smooth-Core/n-10 Collector Inlet Headwall is engineered for optimizing the flow of surface waters into gravity flow n-10 pipe systems. The product features a glass-smooth surface of HDPE (High-Density Polyethylene) plastic culvert pipe that offers stable and durable long-term flow rates. The design includes an arc to ease water flow into the outlet orifice, thereby preventing water recirculation back-flows that can slow down water entry into pipes. The headwall is particularly useful in trench or ditch water management, providing a seamless entryway into CPP Smooth-Core/n-10 pipe systems. Additionally, the use of an erosion-resistant sediment trap, made of stone at the discharge end, can mitigate sediment-related flow restrictions, ensuring optimal hydraulic performance.
CPP - Plastic Flared End Outlet for Soil Erosion Control
CPP Plastic Flared End Outlets are designed to mitigate soil erosion at the outlet ends of CPP pipe systems. Constructed from HDPE plastic, these flared ends offer durable and efficient erosion control. Available in sizes ranging from 12 inches to 36 inches, they provide flexibility for various applications. Additionally, metal flared ends are offered in sizes from 8 inches to 48 inches. These products are essential for enhancing the longevity and performance of CPP pipe installations by minimizing erosion and maintaining the integrity of the surrounding environment.
