ASTM A671 is a standard specification for Electric-Fusion-Welded (EFW) steel pipe for atmospheric and lower temperatures
CC60: “CC60” is the grade designation within the ASTM A671 specification. In this case, “CC60” represents a carbon steel grade with a minimum yield strength same as ASTM A516 grade 60.
EFW.EFW stands for Electric-Fusion-Welded, which refers to the manufacturing process used to produce these pipes. EFW pipes are made by forming and welding flat steel plates into cylindrical shapes using electric fusion welding processes.
ASTM A671 CC60 EFW pipes are commonly used in various industries and applications where moderate strength and good weldability are required, and where the operating temperatures are relatively low. These pipes are suitable for use in atmospheric and lower temperature environments, such as water transmission, structural applications, and some process piping applications.
A516 Gr 60 steel plate is carbon steel for making pressure vessels, such as oil tanks. A516 Gr 60 composition consists of carbon, silicon, manganese, phosphorus, sulfur, aluminum, chromium, copper, nickel, molybdenum, niobium, titanium and vanadium.
ASTM A516 Gr 60 composition:
| Grade | Max. C % for thickness t (mm) | Mn % for thickness t (mm) | Si % | P % max | S % max | ||||
| 6-12.5mm | 12.5-25mm | 25-50mm | >50mm | ≤12.5mm | >12.5mm | ||||
| A516 Gr 60 | 0.21 | 0.23 | 0.23 | 0.25 | 0.6-0.9 | 0.80-1.20 | 0.13-0.45 | 0.035 | 0.035 |
A516 Gr 60 steel plate is normally produced in the As Rolled condition for thickness 1-1/2” and under. Normalizing is required for thickness over 1-1/2”. A516 Gr 60 steel plate has good thermal conductivity and magnetic permeability. The applications of A516 Gr 60 steel plate include calorifiers, oilfield fabrications, valves, storage tanks and condensers, etc.

Standard Specification for Electric-Fusion-Welded Steel Pipe for Atmospheric and Lower Temperatures
Abstract
This specification covers standard requirements for electric-fusion-welded steel pipe with filler metal added, for atmospheric and lower temperatures. The steel pipe shall be fabricated from a pressure vessel quality plate of several analysis and strength levels. Several grades and classes of pipe shall be provided. Grade shall designate the type of plate used while class shall designate the type of heat treatment performed during pipe manufacture. Class shall be designated as to whether the weld is radiographically examined, and as to whether the pipe is pressure tested. Steel samples shall undergo tension and transverse guided weld bend tests and conform to the specified mechanical requirements.
