Savoy Piping Inc. is a leading supplier of API 5L Grade X56 pipes originating from India. We specialize in delivering top-notch pipes to clients worldwide, ensuring their utmost satisfaction. Our extensive inventory comprises pipes stocked in NPS/NB dimensions, adhering to API 5L standards, and available in various thicknesses to meet the specific requirements of our clients. To guarantee the highest quality, all pipes undergo thorough inspection by our dedicated in-house quality control department before they are dispatched to the clients. Moreover, our pipes come with complete traceability and are accompanied by a mill test certificate in accordance with EN 10204 3.1 standards.
API 5L X56 Pipes possess a remarkable Minimum Tensile Strength of 386 MPA, Surpassing American Petroleum Institute 5L GR. X56 Pipes in Strength. These Pipes are Highly durable, offering Long-Term Functionality and Cost-Effectiveness by Reducing the need for Frequent Replacements. Additionally, they undergo Heat Treatment to Enhance Mechanical Strength and Decrease Hardness. With their Exceptional Tensile strength, these Pipes are well-suited for Drilling Operations. They exhibit Excellent Corrosion Resistance and can withstand High-Pressure Environments, making them ideal for the Petroleum, Petrochemical, Oil, and Gas Industries.
Grade X56 Pipes are Commonly used to Transport Gas, Steam, and Fluids from Offshore Sites. Furthermore, API 5L X56 Line Pipes can be Galvanized with Zinc through Hot or Cold Processes, Providing added Protection Against Corrosion and rusting. Grade X56 Pipes Exhibit Superior Resistance to Corrosion, making them suitable for Sour Services where Sulfur Stress Corrosion is prevalent. The Pipes are Categorized into two differentiation levels: PSL-1 and PSL-2. PSL-1 Pipes do not Require Impact and Non-Destructive Testing, as both Levels have Distinct Requirements and Material Compositions.
API 5L X56 Pipe indicates 56000 PSI minimum Yield Strength and 71000 PSI Minimum Ultimate Ttensile strength API 5L X56 Pipe comes in Seamless and Welded steel line pipe for pipeline transportation systems in the petroleum and natural gas industries. API 5L X56 Pipe is suitable for conveying gas, water, and oil.The two digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade.Manganese sulphides are typical inclusions in all manganese alloyed steels. Because they tend to segregate resulting in reduced impact strength, sulphure content needs to be minimized. We specify maximum 0.007%.
Final operations performed during pipe manufacturing that affect attribute compliance as required in this Standard (except chemical composition and dimensions) shall have their processes validated. Those processes requiring validation are the following:
the production of API 5L X56 Pipe and weld seams in COW pipe, the first pass shall be continuous and made by gas-metal arc welding followed by submerged-arc welding, with at least one submerged-arc welding pass made on the inside of the pipe and at least one submerged-arc welding pass made on the outside of the pipe, wherein the gas-metal arc weld bead is not completely removed by the submerged arc welding passes.
The production API 5L X56 Pipe and weld seams in SAW pipe, at least one submerged-arc welding pass shall be made on the inside of the pipe and at least one submerged-arc welding pass shall be made on the outside of the pipe.

The ANSI / API 5L standard outlines the production requirements for two product levels, namely PSL1 and PSL2, of both seamless and Welded steel pipes. These pipes are specifically designed for use in pipelines involved in the transportation of petroleum and Natural Gas. In case the material is intended for a sour service application, Annex H provides relevant guidelines. Similarly, for offshore service applications, Annex J of the API 5L 45th Edition serves as a reference point.

SMLS – Seamless, without weld |
In the production of pipes, the raw materials such as ingots, blooms, billets, coils, or plates must undergo specific manufacturing processes. These processes include basic oxygen, electric furnace, or open hearth, either individually or in conjunction with a ladle refining process. When manufacturing pipes classified as PSL2 (Pipe Specification Level 2), the steel used must be subjected to a fine grain practice, ensuring its quality. Additionally, it is crucial that the coil or plate used for PSL2 pipe does not contain any repair welds.
