2017EDITION 2 PAM Cast Iron Drainage Solutions

• Cast iron has the proven strength and crush resistance to withstand the weight of the concrete and remain robust during the pouring process unlike the more volatile lighter-weight plastic materials which can require filling to weigh them down. • Cast iron is not affected by the high temperatures generated

Crushing-Strength Of Materials. Reduced To A Uniform ...

The Crushing-strength of any body is in proportion to the area of its section, and inversely as its height. In tapered columns the strength is determined by the least diameter. With cast-iron, a pressure beyond 26,680 pounds per square inch is of little, if any, use in practice.

Sewage pipes made of cast iron – recycling over centuries ...

Minimum tensile strength: 150 MPa for fittings, 200 MPa for pipes. Compressive strength. approx. 3 to 4 times the value of the minimum tensile strength. Shearing strength: 1.1 to 1.6 times the value of the minimum tensile strength. Crushing strength: 350 MPa (for DN < 250) 332 MPa (for DN = 250 or larger) Poisson‘s number: 0.3. Length expansion coefficient:Density: approx. 7.2 kg/​dm³ (71,5 KN/​m³)

Safe Or Working Stresses For Cast Iron, Wrought Iron, And ...

Thus, taking the ultimate strength of iron at 20 tons per inch, and the working stress allowed by the Board of Trade for bridges at 20/5 = 5 tons, they infer that the ultimate strength of steel may very safely be taken at 26 tons per inch, and the working stress applied to it at 26/4 = …

Lecture 4. Pipes Materials and Loads

Strength of pipes: The crushing strength of sewer pipes is determined by the three-edge bearing test. The pipe is stressed until failure occurs. Table (3) gives the minimum crushing strength for clay pipes. Strength requirements for reinforced concrete pipes are given in table 4, for this table the crushing force correspond to 0.25mm crack.
