Non-Destructive Testing (NDT)

This method consists of performing a direct or indirect visual examination of the part or structure to be analyzed. In this type of test, the primary instrument is the human eye; however, to validate observations, various tools such as mirrors, videoscopes, and/or borescopes are commonly used.
This technique allows inspections to be carried out quickly and easily.

The magnetic particle inspection method is used to detect surface and near-surface discontinuities in ferromagnetic materials.
The part being examined must first be magnetized; any discontinuities located at or close to the surface will create a magnetic flux leakage field, causing the applied magnetic particles to accumulate and deposit over the anomalies present in the inspected structure.

Hydrostatic testing is a non-destructive test used to verify the physical integrity of a pipeline or system. Water is pumped into the line at a pressure higher than its operating pressure and maintained for a predetermined period, which varies according to the length of the section being tested.
The purpose is to verify the tightness of flanged fittings and welds, using water—or, when necessary, a non-corrosive fluid—as the primary testing medium.

Hydrostatic testing allows us to:

• Determine the quality of fabrication or repair work performed on the line or equipment
• Validate operating conditions to ensure the safety of personnel and facilities
• Detect leaks
• Verify mechanical strength
• Test the tightness and integrity of system components

The manufacturing of components—whether through forming and cutting operations, machining, molding, or special processes—requires dimensional control both during and after production.
Dimensional inspection ensures that the part is suitable for its intended use and that it complies with the technical specifications indicated in the drawings.

It is a fundamental step in the production process, as it determines the acceptance or rejection of parts based on the tolerances permitted in manufacturing.

This technique consists of performing Non-Destructive Testing using penetrant liquids that, when seeping into discontinuities, are retained in narrow openings, allowing the detection and evaluation of anomalies present in the structure.
The test is carried out by applying a penetrant liquid to the material under examination, removing the excess from the surface, allowing it to dry, and then applying a developer that enables the inspection and identification of any discontinuities.

Inspection of drilling rig masts, service rig masts, and substructures. The purpose of this inspection is to detect defects such as cracks, mechanical damage, or missing elements that may indicate severe damage or potential failures in the operation of the equipment. Depending on the severity or location of these findings, they may warrant removing the equipment from service or sending it for immediate repair.

This technique consists of transmitting high-frequency sound waves into the material to be inspected. As the ultrasonic wave travels through the part, any imperfection or discontinuity generates an echo signal, which allows the detected anomaly to be evaluated.
This method is suitable for inspecting large components or structures.

Ultrasonic testing enables:

• Detection and characterization of discontinuities
• Thickness measurement, including the extent and degree of corrosion
• Determination of physical properties
• Evaluation of bonding characteristics between materials

Phased Array Ultrasonic Testing (PAUT) is an advanced Non-Destructive Testing (NDT) method that uses multiple electronically controlled ultrasonic elements to generate beams that can be steered, focused, and swept through the material without physically moving the probe.

Unlike conventional ultrasonic testing, PAUT provides detailed cross-sectional imaging (A-scan, B-scan, and S-scan), enabling more accurate detection, characterization, and sizing of internal discontinuities.

This method is especially effective for complex inspections, challenging geometries, and critical components in industries such as Oil & Gas, petrochemical, energy, metalworking, and welded structures.

PAUT allows for:

• Detection and sizing of internal discontinuities
• High-reliability evaluation of critical welds
• Inspection of components with complex geometries
• Real-time imaging for more precise analysis
• Reduced inspection time with higher accuracy
• Digital, traceable data recording and documentation

At MAKING, we have qualified personnel and state-of-the-art equipment to perform Phased Array inspections, ensuring reliable, repeatable results aligned with international standards.

Lifting equipment inspection is a critical process in industrial operations and the Oil & Gas sector. It involves evaluating the condition, integrity, and performance of equipment designed to lift, move, or support loads, ensuring compliance with safety requirements, industry standards, and operational demands.

Lifting equipment includes slings, shackles, eye bolts, hooks, wire ropes, chains, sheaves, spreader bars, synthetic slings, lifting accessories, and critical components used in drilling, pulling, workover, and lifting operations.

At MAKING, we perform visual, dimensional, and non-destructive inspections in accordance with applicable standards (API, ASME, ISO), ensuring that equipment maintains its reliability and operational safety.

Inspection services allow for:

• Verification of structural integrity and proper operating condition
• Detection of wear, deformation, or damage
• Prevention of failures and accidents during lifting operations
• Certification of equipment condition according to regulations
• Extending the service life of critical components

MAKING has qualified personnel and certified procedures to perform lifting equipment inspections with precision, traceability, and a strong focus on operational safety.

BHA (Bottom Hole Assembly) drilling tools inspection under the DS-1 standard is a critical process to ensure the integrity, reliability, and performance of the components used in drilling operations.

The DS-1 (Drill Stem Inspection Standard) establishes international guidelines for the inspection, classification, maintenance, and acceptance of drill string tools and components, ensuring compliance with structural, dimensional, and safety requirements across the industry.

These inspections cover components such as drill collars, heavy-weight drill pipe, stabilizers, subs, reamers, bit boxes, NMDC, special tools, and other elements that form part of the BHA.

At MAKING, we conduct visual, dimensional, and non-destructive inspections (MT, UT, EMI) according to DS-1 criteria, ensuring traceability, reliability, and regulatory compliance.

DS-1 inspection allows for:

• Detecting wear, erosion, cracks, and internal discontinuities
• Verifying critical dimensional tolerances
• Preventing failures during drilling operations
• Classifying components according to DS-1 categories
• Extending the service life of high-value tools
• Reducing non-productive time (NPT)

MAKING has qualified personnel, specialized equipment, and documented procedures to ensure thorough evaluation of BHA components in accordance with the DS-1 standard.
