Introduction:

At Shekari-Mohsen Contractor Group, we take pride in offering comprehensive pipeline inspection services for both the construction and service phases. With a strong focus on API 1104, ASME B31.4, and ASME B31.8 standards, we are committed to ensuring the integrity, safety, and compliance of pipelines across various industries.

Understanding the Importance of Pipeline Inspections:

Pipelines are critical infrastructures for the transportation of fluids, such as oil, gas, and water, over long distances. The integrity of pipelines is paramount to prevent leaks, spills, and other hazardous incidents that can have severe consequences for the environment, public safety, and the economy. Regular inspections are essential to identify potential issues, assess the condition of pipelines, and ensure the continued safe and efficient operation of these vital assets.

API 1104: Standards for Welding of Pipelines:

API 1104 is a widely recognized standard developed by the American Petroleum Institute (API) for the welding of pipelines. It provides comprehensive guidelines for welding procedures, qualification of welders, and inspection requirements during the construction phase. Our company specializes in API 1104 inspections, adhering to the stringent standards set forth to ensure the highest level of welding quality and compliance for our clients’ pipelines.

ASME B31.4 and ASME B31.8: Standards for Pipeline Construction and Maintenance:

ASME B31.4 and ASME B31.8 are key standards developed by the American Society of Mechanical Engineers (ASME) for the design, construction, and maintenance of liquid and gas transmission pipelines, respectively. These standards outline requirements for material selection, construction techniques, inspection procedures, and integrity management during both the construction and service phases of pipelines. Our company’s expertise in ASME B31.4 and ASME B31.8 standards enables us to help clients maintain the integrity, safety, and compliance of their pipelines throughout their lifecycle. Our company offers comprehensive inspection services tailored to the construction phase, including

Pipeline Inspection Services in the Construction Phase:

During the construction phase of pipelines, it is crucial to ensure that the pipelines are built in accordance with API 1104, ASME B31.4, and ASME B31.8 standards, as well as other applicable codes and regulations. Our company offers comprehensive inspection services tailored to the construction phase, including:

1. Welding Inspections:

Our highly trained inspectors conduct rigorous inspections of pipeline welds, ensuring compliance with API 1104 standards and verifying the quality of weld joints. We employ various non-destructive testing (NDT) methods, such as radiographic testing (RT), ultrasonic testing (UT), and magnetic particle testing (MT), to detect any welding defects or discontinuities that may compromise the pipeline’s integrity.

1. Material Inspections:

The selection of appropriate materials is critical for pipeline construction. Our inspectors thoroughly examine the materials used, including pipes, coatings, and fittings, to ensure they meet the specified requirements and are suitable for the intended service conditions. This helps prevent issues like corrosion, leaks, and premature failures that may arise due to substandard materials.

1. Pipeline Coating and Inspections:

Coatings play a vital role in protecting pipelines from corrosion and external damage. Our company conducts thorough inspections of pipeline coatings, including Holiday inspections, thickness measurements, and adhesion tests, to ensure their proper application and effectiveness. This helps extend the lifespan of pipelines and reduces the risk of corrosion-related issues.

Pipeline Inspection Services in the Service Phase:

Once pipelines are operational, regular inspections are necessary to monitor their condition, detect any deterioration, and ensure ongoing compliance with regulations. Our company offers a range of inspection services for pipeline systems in the service phase, including:

1. In-Line Inspection (ILI):

In-line inspection, commonly known as smart pigging, involves using sophisticated tools and technologies to inspect the internal condition of pipelines. Our company provides ILI services that utilize intelligent pigs equipped with advanced sensors to identify issues such as corrosion, cracks, deformations, and blockages. This enables us to assess the integrity of the pipeline and recommend appropriate maintenance and repair measures.

1. External Corrosion Surveys:

Corrosion is a significant threat to pipeline integrity. Our company conducts comprehensive external corrosion surveys using various techniques, such as close interval potential surveys (CIPS) and direct current voltage gradient surveys (DCVG). These surveys help identify areas of corrosion and determine the effectiveness of corrosion protection measures, allowing for timely remedial actions.

1. Cathodic Protection System Inspections:

Cathodic protection is a widely used method to prevent corrosion by creating an electrochemical reaction that protects the pipeline. Our inspectors conduct detailed inspections of cathodic protection systems, including measurements of electrical potentials and current densities, to ensure their proper functioning. This helps maintain the effectiveness of corrosion prevention measures and prolong the lifespan of the pipeline.
