Pipe & Fittings

API 5LC corrosion resistance alloy line pipe

We manufacture seamless alloy line pipe with improved corrosion resistant properties. The pipes provide improved corrosion resistance suitable for use in conveying gas, water, and oil in both the oil and natural gas industries.

The size designations are nominal pipe sizes (NPS). In the text paragraphs herein, where pipe size limits (or size ranges) are given, these are outside diameter sizes except where stated to be nominal. These outside diameter size limits and ranges apply also to the corresponding nominal sizes. The primary product is beveled pipe. If plain-end square cut or other special end preparation is desired, this shall be subject to agreement between the purchaser and manufacturer. Included are NPS 1 in. through 42 in. Grades covered by this specification are LC30-1812, LC52-1200, LC65-2205, LC65-2506, LC30-2242, and LC80-2507 1.

All pipes are manufactured at a facility licensed by API

Special processes for manufacturing conditions of seamless pipes

Heat Treatment

Pipe furnished to this specification may be as-rolled, solution annealed, except LC52-1200, which shall be quenched and tempered. Other appropriate heat treatment may be agreed upon between purchaser and manufacturer.

Traceability

The manufacturer shall establish and follow procedures for maintaining heat and/or lot identity until all required heat and/or lot tests are performed and conformance with specification requirements has been shown.

Hydrogen Sulfide Environments

For any grade, if the intended application is for use in an environment that contains hydrogen sulfide then this should be clearly stated in the purchase agreement.

Where use in an environment containing hydrogen sulfide is stated in the purchase agreement, all requirements of ANSI/NACE MR0175 and ISO 15156-3 shall be satisfied.

In such cases, sour service designation marking according to ANSI/NACE MR0175 and ISO15156-3, Annex C shall be applied.
