Are cast iron standards?

This standard was first pubIished in 1950 and subsequently revised in 1962, 1970, 1978 and 1993. The Pig Iron and Cast Iron Sectional Committee decided to revise IS 210 by merging it with IS 6331 : 1987. The production of castings in the higher grades of grey cast iron often involves special techniques.

What is ASTM A74?

ASTM A74, 2021 Edition, March 1, 2021 – Standard Specification for Cast Iron Soil Pipe and Fittings. This specification covers cast iron soil pipe and fittings for use in gravity flow plumbing, drain, waste and vent sanitary, and storm water applications.

What is cast iron composition?

cast iron, an alloy of iron that contains 2 to 4 percent carbon, along with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus. It is made by reducing iron ore in a blast furnace.

What is the density of cast iron?

Known density of selected metals and alloys

Metal or alloy Density (g/cm3)
Iron (grey cast) 7.20
Tin 7.30
Steel (carbon) 7.86
Stainless steels 7.65–8.03

What is the product standard number for cast iron soil pipe and fittings?

ASTM A74 – 21
ASTM A74 – 21 Standard Specification for Cast Iron Soil Pipe and Fittings.

How is cast iron joined?

There are generally three methods used for joining cast iron soil pipe. Hub and spigot cast iron soil pipe may be joined by the compression gasket or a caulked joint. Hubless cast iron soil pipe are joined by using a hubless coupling. The gasket must be inserted into the hub completely.

Is code for DI pipe?

A separate standard IS -9523 covers the specification on such fittings. 1.5 Fittings conforming to IS 13382 may also be used with ductile iron pipes, when the pressure require- ments matches. The following Indian Standards contain provisions, which through reference in this text, constitute provisions of this standard.

What is class K9 ductile pipe?

Stockholder DI pipe Class k9 in india. Class K9 DI pipe specification is based on the Nominal Wall Thickness as well as the Nominal Diameter of the pipe. DI K9 Pipes are heavier than Ductile Iron Class K7 pipes. Ductile Class K9 pipes are resistant to corrosion and there is no need for cathodic protection for them.

How is cast iron made?

Cast iron is formed by smelting iron ore, or melting pig iron (an intermediate product of iron ore extraction), and mixing it with scrap metals and other alloys. The liquid mixture is then poured into molds and allowed to cool and solidify.

What is the unit weight of cast iron?

specific weight metal and alloy

metal or alloy weight (kg/dm3)

lead bronze 8.8 – 9.5
iron 7.85
cast iron 6.8 – 7.8

What are the ASTM standards for cast iron?

Cast Iron Standards. ASTM’s ferroalloy and casting standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of iron alloys and their castings. The iron castings can be of the ferritic, austenitic, gray, cupola, pearlitic, ductile, or malleable types.
