what is sour service pipe and differences with normal pipes
API 5L line pipe (Seamless and welded pipe) of all grades have PSL1 and PSL2 two product specifications, they are different on chemical composition, manufacturing processes, mechanical strength, heat treatment, test records, traceability etc.Line pipes in API 5L PSL2 is higher than PSL1. a. PSL is the short name of product standard level. The product standard level of line pipe have PSL1
Sour service line pipe requires a strictly control on the chemical composition. So to protect pipe from corrosive environments like H2S, low carbon and low CEPcm value will reduce the martensite which sensitive to H bubble, so to improve the corrosive resistance to H2S. Moreover, P and S also should be less than normal line pipes. API 5L X65 Sour Service PipeAPI 5L L450 SSC Pipe Savoy Piping Inc.

Sour Service Steel Grades offered by U. S. Steel Tubular Products:API L80 is manufactured to API specification 5CT. This is a controlled yield strength material with a hardness testing requirement. L80 is often used in wells with sour (H2S) environments. API C90 is an API controlled yield strength grade generally for use in sour condensate API pipes & tubes:Line Pipe for Sour ServiceLine pipe steels used in sour service are prone to hydrogen-induced cracking (HIC) depending on metallurgical and environmental factors. The metallurgical factors consist of alloying elements, microstructure, strength, segregation, and shape of non-metallic inclusions.
Dec 01, 2017 · The only difference between the 2 grades is only in the testing requirements. A672 requires weld sample drawn from a 500ft length of pipe and allows you to double the samples in case, original sample fails. A671 requires weld sample drawn from a 200ft length of pipe with no provision for a rejected weld. Understanding difference in different grades Difference between sour service and non sour service Sour service can be defined as a situation where in the environment there exists Hydrogen Sulfide (H2S). This substance present in the environment is hazardous to the human health. It could also significantly impact steel drilling tubulars performances in service operations as well.
Pipes. Pipes are used mainly for transportation of fluids and gases like water, oil, gas, propane etc. The inside key measurement is the inside and outside diameter and pressure rating is important. Pipe Bollards use pipes because they require rigidity, resistance, and strength to cope with impact pressure.

2. Wall Thickness. The wall thickness is an important factor while differentiating between pipes and tubes. The thickness of a tubing is often specified by a gauge for thinner thickness and for thicker tubing it is indicated by fractions of an inch or millimeter.The normal range of tubing is 20 gauge, which is 0.035 inch up to a thickness of 2 inches. Technical requirements for Pipes & Fittings4.2 All welded pipes / fittings in sour service shall be HIC tested, if required by the project specification. It shall be conducted for one pipe / fitting per heat in accordance with NACE TM-0284 Solution A with acceptance criteria as specified in NACE MR-0175. 5. Positive material identification
Pipe, on the other hand, is always round and rigid. It cannot be shaped easily without the use of a special equipment. Pipes are usually seamless and pressure rated to avoid leakages as they usually carry liquids or gases. 4. TOLERANCE. Comparing the tolerance of both tubes and pipes, the tolerance for pipes is looser than tubes. Pipes are What is NACE MR0175/ISO 15156 Pipe and FittingsMechanical properties of tensile strength, and yield strength is same with general pipes referred to corresponding standards. NACE Test Methods For sour service steel pipe, plate, fittings, commonly there are two test methods referred NACE. HIC and SSC. HIC is Hydrogen Induced Cracking. HIC test is a mandatory test for NACE pipe and fittings.
