What should be checked during Orifice flange inspection?

During the inspection of orifice flanges, the following items should be checked:

Butt Weld Root: Verify that the butt weld root is flush ground and smooth. It should be free from any irregularities, such as bumps or protrusions, that could affect the proper installation and sealing of the orifice flange.
Visual Inspection: Perform a visual inspection of the orifice flange to ensure there are no visible defects, such as cracks, pits, or corrosion. Check for any signs of damage or wear that could compromise the integrity of the flange.
Penetrant Testing (PT): Conduct penetrant testing on the orifice flange to detect any surface discontinuities that may not be visible to the naked eye. This non-destructive testing method can identify potential defects, such as cracks or leaks, that could impact the performance of the flange.
Orifice Plate Identification: Check the orifice plate identification number to ensure it matches the information specified on the isometric drawing. Verify that the orifice plate is correctly identified and labeled for proper installation and alignment within the piping system.

2. What is 4 types of inspection action point found in ITP?

In an Inspection and Test Plan (ITP), there are typically four types of inspection action points:

Hold: This means that the QA/QC organization must be notified in advance of the timing of the inspection or test. The inspection or test should not be carried out without a representative from the QA/QC organization in attendance. This ensures that the necessary quality control measures are implemented during the inspection or test.
Witness: Similar to a hold point, the QA/QC organization must be notified in advance of the timing of the inspection or test. However, if the QA/QC representative is not present, the inspection or test can proceed as scheduled. This allows for flexibility in scheduling while still maintaining the option for QA/QC oversight if required.
Surveillance: In this type of inspection action point, the QA/QC organization monitors the work in progress without prior notice from the construction organization. This continuous monitoring helps ensure that the work is being carried out according to the specified quality standards and procedures.
Review: This involves the review and approval of all relevant documents, such as design drawings, specifications, procedures, and test reports. The QA/QC organization carefully examines these documents to ensure compliance with the project requirements and applicable standards.

3. What is NCR?

NCR stands for Non-Conformity Report. It is a documented record that reports any deviation or non-conformity from the specified requirements or standards. When an issue or non-conformance is identified during an inspection, testing, or quality control process, an NCR is raised to document the details of the non-conformity. The NCR includes information such as the nature of the non-conformity, its location, the impact on the project or product, and any corrective actions or measures taken to address the issue. NCRs play an important role in quality management systems as they help identify and rectify deviations to ensure compliance with the required specifications and standards.

4. What is schedule Q?

“Schedule Q” relates to a standardized term or document in the context of quality requirements for contractors or subcontractors of Saudi Aramco. Schedule Q stands for Owner’s minimum quality requirements for contractors/sub-contractors quality system.

5. What are Types of gaskets?

Here are five common types of gaskets:

Metallic gaskets:

Spiral Wound Gasket: This type of gasket consists of a metallic winding (typically stainless steel) and a nonmetallic filler material (such as graphite) wound together. It provides excellent resilience and sealing properties.
O-Ring Gasket: O-ring gaskets are round, elastomeric seals typically made of rubber. They are designed to fit into a groove and create a tight seal between two mating surfaces.
Ring Joint Gasket: Ring joint gaskets are metal gaskets designed for high-pressure and high-temperature applications. They have a specific shape that allows them to create a reliable seal when compressed between two flanges.

Nonmetallic gaskets:

Non-Asbestos Gasket: Non-asbestos gaskets are made from materials other than asbestos, which was commonly used in the past but is now restricted due to health concerns. These gaskets can be made from various materials such as aramid fibers, synthetic rubber, or graphite.
Teflon Gasket: Teflon gaskets, also known as PTFE (polytetrafluoroethylene) gaskets, are made from a high-performance plastic known for its excellent chemical resistance. They are commonly used in applications that involve corrosive fluids or extreme temperatures.

6. What is responsibility of QC material inspection procedure?

The responsibilities of the QC (Quality Control) material inspection procedure include:

Matching physical conditions in the field to the service conditions shown on the drawings and hardware specifications. This ensures that the materials being inspected are suitable for the intended application.
Specifying the marking and color coding requirements for materials. This helps in proper identification and traceability of the materials throughout the project. Additionally, conducting Positive Material Identification (PMI) checks to verify the composition and quality of the materials.
Identifying the grade of materials based on the ASME specifications listed on the drawings or provided by the manufacturer. This ensures that the materials meet the required standards and specifications.
Specifying the correct class, rating, size, and schedule of fittings and flanges based on the markings and mill certificates. This ensures that the selected fittings and flanges are suitable for the specific application and can withstand the required pressure and temperature conditions.
Verifying the correct schedule of pipes using vernier calipers or other measuring tools. This ensures that the pipe materials have the correct thickness and meet the specified schedule requirements.

7. What is fit up inspection explain?

Fit-up inspection refers to the examination and verification of the alignment and preparation of components prior to welding. It ensures that the joint configuration and dimensions meet the specified requirements for proper welding.

During fit-up inspection, the following aspects are typically checked:

Root Gap: The fit-up inspector verifies that the gap between the edges of the joint is within the allowable limits specified in the welding procedure. This gap ensures proper penetration and fusion during welding.
Root Land: The fit-up inspector checks the width of the flat surface or land at the root of the joint. It ensures that the land is sufficient to support the weld and maintain proper alignment during welding.
Bevel Angle: The fit-up inspector confirms that the bevel angle of the joint is within the allowable range specified in the welding procedure. The bevel angle affects the depth of penetration and the quality of the weld.
Fit-up Requirements: The fit-up inspector examines the overall fit-up of the components and ensures that they meet the basic requirements for welding, such as proper alignment, edge preparation, and cleanliness. It includes checking for any gaps, misalignment, or defects that could affect the weld quality.

8. What is MTC?

A Mill Test Certificate (MTC), also known as a Mill Test Report (MTR), is a document provided by the manufacturer of a product, typically in the steel industry. It certifies that the product meets the required chemical and mechanical properties as specified by relevant standards, codes, or customer requirements.

The MTC contains important information about the product, including details about its composition, mechanical properties, heat treatment, dimensions, and any additional testing conducted. It serves as evidence that the product has been tested and inspected during the manufacturing process and meets the necessary quality and compliance standards.

MTCs are commonly required for various applications, such as in the construction, oil and gas, and manufacturing industries, to ensure the quality and traceability of materials used in projects.
