Product Introduction

API 5L PIPES - API 5L SEAMLESS LINE PIPES

This API 5L Specification Covers Seamless and Welded Steel Line Pipe. It includes standard-weight and Extra-Strong threaded Line Pipe. It includes standard-weight and extra-strong threaded line pipe; and standard-weight plain-end, regular-weight plain-end, special plain-end, extra-strong plain-end, special plain-end, extra-strong plain-end pipe; as as well as bell and spigot and through-the-flow line(TFL) pipe.

The purpose of this specification is to provide standards for pipe suitable for use in conveying gas, water, and oil in both the oil and natural gas industries

Grades covered by this specification are A25 ,A ,B (and the following "X" Grades), X42, X46, X52, X56, X60, X65, X70, X80. The two digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade.

We can supply full range of API 5L Seamless Pipes in PSL-1 & PSL-2 line pipe.

We carry a full inventory of API 5L Pipe Carbon Steel Pipe products in a variety of sizes to meet the structural piping requirements for applications the water, petroleum, oil & gas and other industries. API 5L Seamless Pipe Carbon Steel Pipe can be Structural in Nature or used in Fluid, Gas, Oil Transmission.

The grade indicates the testing methods required for a given application. It is critical that structural grades of Carbon Steel Pipe not be used for Pressure or Fluid applications.

API 5L Line Pipe can be either seamless or welded. Applications for API 5L include, but are not limited to: petroleum, petrochemical, natural gas industries, and waterworks.

My company is a pipe manufacturer and pipe distributor in Middle East, Far East and Africa Region that provides API 5L line pipe from 1/2" to 64" in diameter, in grades X42, X46, X52, X60, X65, & X70.

Axc   is the applicable tensile test piece cross-sectional area, expressed in square millimeters (square inches) , as follows
– For circular cross-section test pieces, 130mm2 (0.20 in2) for 12.7 mm (0.500 in) and 8.9 mm (.350 in) diameter test pieces; and 65 mm2 (0.10 in2) for 6.4 mm (0.250in) diameter test pieces.

   U is the specified minimum tensile strength, expressed in megapascals (pounds per square inch
g. Lower values fo R10,5IRm may be specified by agreement
h. for grades > x90 refer to the full API5L specification.

Hydrostatic Test

Pipe to withstand a hydrostatic test without leakage through the weld seam or the pipe body. Jointers need not be hydrostatic tested provide the pipe sections used were successfully tested.

Bend Test

No cracks shall occur in any portion of the test piece and no opening of the weld shall occur.

Flattening Test

Acceptance criteria for flattening test shall be:

  • EW pipes D<12.750 in:

  • X60 with T 500in. There shall be no opening of the weld before the distance between the plates is less than 66% of the original outside diameter. For all grades and wall, 50%.

  • For pipe with a D/t > 10, there shall be no opening of the weld before the distance between the plates is less than 30% of the original outside diameter.

  • For other sizes refer to the full API 5L specification.

CVN Impact Test For PSL2

Many PSL2 pipe sizes and grades require CVN. Seamless pipe is to be tested in the body. Welded pipe is to be tested in the body, pipe weld and heat-affected zone. Refer to the full API 5L specification for the chart of sizes and grades and required absorbed energy values.
