10# Seamless Steel Pipe

Classification :

Seamless pipe, as the name suggests, is a pipe without a seam or a weld-joint. Seamless Steel Pipe is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow pipe.

Product introduction

This specification covers wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. The pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation. All seamless and welded pipes shall be treated to control their micro-structure. Tensile tests, impact tests, hydro-static tests, and nondestructive electric tests shall be made in accordance to specified requirements.
1. Scope
1.1 This specification covers nominal (average) wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. Several grades of ferric steel are included as listed in Table 1. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse affect on low-temperature impact properties.
1.2 Supplementary Requirement S1 of an optional nature is provided. This shall apply only when specified by the purchaser.
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in non-conformance with the specification. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.
