With the riser-type manhole, the riser is usually aligned with the outside of the main pipe rather than centered over the pipe, so that any vertical loads transmitted can be resist-ed more effectively by the main pipe. This also allows steps to be added to the outermost wall with a smooth transition to the floor.

This document provides guidance on designing corrugated steel pipe (CSP) manhole risers. It describes two common types of manholes - riser-type and shaft-type. Riser-type manholes have the riser aligned with the outside of the main pipe, while shaft-type manholes are …

Manholes, risers, inlets, and outlets are made from CSP, CASP, or CAP in any available thickness. Corrugations may be 2-2/3 inch x ½ inch, 3 inch x 1 inch, or 5 inch x 1 inch. Available with solid cover or open grating, with or without welded bottom.

ContraFlame® combined cryogenic spill protection (CSP) and passive fire protection (PFP) has been tested for 60 minutes jet fire protection and two hour cryogenic spill protection. Incorporates phenolic fibreglass reinforced tiles and our ContraFlame® C50 thermal insulation material

Corrugated steel pipe makes an excellent, cost-effective manhole for use with CSP cul-verts, storm sewers and underground detention systems. The riser manhole and the shaft manhole are two common types that are used. These are shown below. The riser man-hole is used where the mainline is a larger diameter than the manhole. The riser is typi-

CSP pipe connection systems provide excellent resistance to shear and separation across the joint and thus compensate for settlement and shifting of surrounding soils. CSP pipe connections can be supplied in varying widths and with several different types of neoprene

csp fittings, tee, elbows, ect. Concentric Reducer (or Eccentric) Lateral Wye Chapter 2 . Figure 2.23 Shop fittings for corrugated steel pipe and pipe arch. Shop fabricated fittings are available for a wide variety of conditions. Moderate horizontal curvature in a culvert or sewer can be achieved with ordinary couplings.

Armtec’s CSP Pipe and Multi Plate Culverts are the benchmark standard within the industry. Armtec have strongly contributed toward the success of many of CME’s past projects and we will continue working together, improving infrastructure that benefits our local communities.

Corrugated steel pipe band connectors. CSP Field Joints For unusual conditions, such as high pressures, inside existing pipe, jacking or boring pipe, anc cial designs are available. New joints can be rg particular requirements.
