Standards &

ASTM A 120-84 Standard for

Pipe, Steel, Black and Hot Dipped Zinc-

Coated (Galvanized) Welded and Seamless,

for Ordinary Uses

This covers black and hot-dipped galvanized welded and

seamless steel pipe in NPS 1/8" to NPS 16" inclusive. Formerly under

the jurisdiction of ASTM Committee A-1 on Steel, Stainless Steel, and

Related Alloys, this was discontinued in 1988 and

replaced by A 53, for Pipe, Steel, Black and Hot-

Dipped, Zinc-Coated Welded and Seamless.

AWWA Standard for Steel Pipe Six Inches

and Larger

By reference, the former AWWA C202 included API 5L and 5LX pipe

grades manufactured to the American Petroleum Institute (API)

standards for high pressure applications. With the advent of ASTM

A570 and A572 high strength steels being included in AWWA C200,

API high pressure pipe was omitted from AWWA C200 as being redun-

dant. However, API 5L and 5LX pipe grades fully meet all require-

ments of AWWA C200 and can be used for water works applications if

dictated by availability or other economic considerations.

Scope

Covers SEAMLESS carbon steel nominal wall pipe for high-

temperature service, suitable for bending, and similar

forming operations.

Manufacture

Sizes 1 1/2" and under may be either hot or cold drawn.

Sizes 2" and larger shall be hot unless otherwise

Hydrostatic and Nondestructive

Inspection test pressures produce a stress in the pipe wall equal to

60% of minimum Yield Point at room temperature. Maximum

Pressures are not to exceed 2500 psi for sizes 3" and under, and

2800 psi for the larger sizes. Pressure is maintained for not less than

5 seconds.

Tensile Requirements

Tensile Strength, min. 60,000 psi

Yield Point, min. 35,000 psi

End Finish

NPS 1 1/2" and Smaller: All walls shall be either plain-end square cut,

or plain-end beveled at the option of the manufacturer.

NPS 2" and Larger: Walls through extra strong weights, shall be

plain-end beveled.

NPS 2" and Larger: Walls over extra strong weights, shall be plain-

end square cut.

Plain-end beveled is as plain-end pipe having a bevel angle of

30˚, +5˚ - 0˚, as measured from a line drawn perpendicular to the axis

of the pipe with a root face of 1/16 in. ± 1/32 in.

Dimensions and Weights

The dimensions and weights furnished under this are in

agreement with the standardized dimensions and weights in

ASME B 36.10.

Lengths

Single Random: 16'-22'.

Double Random: Minimum length 22', Minimum average 35'.

Chemical Requirements

Carbon, max A 0.30

Manganese 0.29-1.06

Phosphorus, max 0.035

Sulfur, max 0.035

Silicon, min 0.10

Chrome, max B 0.40

Copper, max B 0.40

Molybdenum, max B 0.15

Nickel, max B 0.40

Vanadium, max B 0.08

A For each reduction of 0.01% below the carbon maximum, an

increase of 0.06% manganese above the maximum will be

permitted up to a maximum of 1.35%.B These elements combined shall not exceed 1%.

Permissible Variations in Outside Diameter

Outside Diameter at any point shall not vary from standard

more than— Over Under

Sizes 11/2" and smaller 1/64" 1/64"

2"–4" 1/32" 1/32"

5"–8" 1/16" 1/32"

10"–18" 3/32" 1/32"

20"–24" 1/8" 1/32"

Permissible Variations in Weights per Foot

Weight of any length shall not vary more than 10% over and 3.5%

under.

Note—Size 4" and smaller—weighed in lots. Larger sizes—by length.

Permissible Variations in Wall Thickness

The minimum wall thickness at any point shall not be more than 12.5%

under the nominal wall thickness
