STANDARD AND LINE PIPE
Standard pipe is intended for ordinary use such as steam, water, air, and gas lines, and plumbing and heating applications. The largest percentage of standard pipe is produced to conform with ASTM Specifications A-120 (discontinued 1988), A-53, and A-1 06. It is manufactured by three basic methods:
A. Continuous Weld: Fastest production and most reasonably priced, but not suitable for high pressure applications. ASTM A53 Type "F".
B.Electric Resistance Weld: Uniform walls, good concentricity, long lengths. ERW pipe is generally limited to a maximum wall of lIt. ASTM A53 Type "E".
C. Seamless: Excellent for high pressure application and can be produced with very heavy wall thickness and in alloy grades. Because of the method of manufacture, the walls are not always uniform. A53 Type US"and A106.
The method of manufacture and the specification selected is dependent on the intended application.
Line pipe is generally intended for use by the oil and gas industry for the conveyance of oil and gas, or miscellaneous industrial use. It is produced to American Petroleum Institutes specification (API) 5L and 5LX. Line pipe is produced in both welded and seamless forms.
