steel, wrought iron, malleable iron, fopper,-brass and bronze, as specified in the ASA B31.5-1962 Code for Pressure Piping.1
Copper and brass must not be used with ammonia.
Other materials are not barred by the code, provided they are of suitable strength and are chemically suitable for use
with the fluid conveyed. The code bare the use of.magnesium base alloys with any halogensted hydrocarbon refrigerant, as
well as the use of zinc, aluminum, die-castings, and magnesium, alloys with methyl chloride.
For temperatures below O' F, the code provides that ma terials shall have a Charpy impact value at the operating
temperature of not less than 15 ft lb using a keyhole notch, but permits-copper, brass and bronze without restrictions;
it permits-ferrous materials not meeting this requirement down to --100 F, provided the design pressure is increased
2 percent for each degree below 0 F. This permits the ordinaiy tines of cast iron refrigerant fittings down to -- 50 F, without
penalty, except for refrigeration applications where a volatile type of refrigerant is used. For-materials suitable for low
temperatures, the code states:
.. "There is a large and constantly growing list of alloy composi tions which meet -these requirements, and it has not been'deemed advisable to infer any limitation by,listing a few.materials suitable for this purpose. Depending on composition and heat treatment, some `carbon steels' meet the requirements for a considerable range of temperatures. In general, the 3 to 4 percent nickel steels are acceptable for quiteTow temperatures, ana the 18 percent chrome-8 percent nickel stainless steels meet requirements to very low temperatures. Various other classes of alloys are also accept able. Apparently minor variations in composition and beat*treat ment make large differences in toughness at low temperatures."
A summary of available data on low temperature materials
is contained in the publication Properties of Metals at Sob-
atmospheric Temperatures, issued in -1941 by the American Society for Testing Materials.
Specific minimum requirements for refrigerant pipe and tubing are set forth in the ASA B9.1-1964 Safety Code for Mechanical Refrigeration, asfollows:
9 Specific Minimum Requirementsfor Refrigerant Pipe and * Tubing
9.3.1 No less than Schedule 80 wall thickness carbon steel or wrought iron pipe shall be used for Group II and Group III r^ frigerant liquid tines for sizes 11 in. and smaller.
No less than Schedule 40 wall thickness carbon steel or wrought iron pipe shall be used for Group I refrigerant liquid lines sizes 6 in. ana smaller. Group 1 and Group 111 refrigerant liquid lines sixes 2 in. through 6 inl and Group I, Group Q, and Group 111 refrigerant vapor lines 6 in. and smaller/
Butt-welded carbon steel and butt-welded wrought iron pipe shall not be used for refrigerant liquid tines.
Cast iron pipe shall not be used for Group I, Group II, or Group III refrigerant tines.
9.3.2 Standard iron pipe size oopper and red brass (not less than 80 percent copper) pipe may be used and rK*11 oonform to ASTM Specification B-42 for copper pipe nH ASTM Specification B-43 for red brass pipe.

\ THREADING PRACTICE
In all threaded pipe for heating and ventilating installsUons the American Standard taper pipe thread, ASA B2.11960 is used., ,Thia thread is cut with a taper rof, .1 in 16 measured'on the diameter of the pipe so as to secure a tight joint. The number of threads per inch varies with the pipe size. Threads for fittings are the same, except that it is regular practice to furnish straight tapped couplings for Schedule.40,pipe 2 in. and;smaller. For steam-pressures in excess of 25 psi, it is recommended that taper-tapped couplings be used to obtain a tight joint. These may be secured by ordering line pipe1 which is used for-qil.,piping, the couplings of which are provided with taper-tapped threads and may be used with regular miltohreaded standard weight pipe. Thread lengths should be in accordance with
