Inspection and Test

1. Production Controls

​

a. Pre-Production Inspection and material input quality controls

​

Pre-production inspections form one of the cornerstones of risk assessment and quality assurance management. Pre-production inspection is the most effective way to verify that your supplier can begin production, meet your specifications or adhere to your quality requirements.

The products you supply from your suppliers, natural gas and oil pipeline equipment (valves, pipes, fittings, etc. as) before starting production, we control the main raw materials and semi-finished products with the inspections we have done. By performing tests and controls according to sampling or ITP approved as 100% we give approval for the production of products. In this way, we determine the risks you may encounter in your projects in advance and ensure that precautions are taken.

During this inspection ATM Vana expert auditor according to the checklist and the approved Inspection & Test Plan (ITP);

• Verifies availability and condition of materials / raw materials / semi-finished products,

• Reviewing the production preparation and planning of the manufacturer,

• Controls the manufacturers machinery and equipment park,

• Performs the necessary destructive or non-destructive tests on the products according to ITP,

• Makes dimensional and visual controls,

• Supervises the suppliers/manufacturers in-house quality control,

• It helps to prepare for future product reviews.

Our pre-production inspections can be made at your supplier and/or company just before production starts or before final assembly begins. A PPI allows you to earn:

• Clear understanding of production schedules,

• Ability to measure your manufacturers ability to meet your needs and quality objectives,

• Ability to detect potential problems that may affect project timing or product quality.

• Assurance that your needs will be met,

• Assurance on the quality of raw materials and semi-finished products and product components.

​

b. Controls and Inspections During Production,

    (DPI or DUPRO - During Production)

​

During production checks and inspection (DPI), or DUPRO, is a process that is performed while production is in progress.quality control inspectionis These quality control inspections are made when the production of the products continues and between 10% and 60% of the production is completed. During this review, we identify production deviations and provide feedback on corrective actions. We recheck for errors during our pre-shipment inspections to verify that these corrective actions have been corrected.

At every stage of the production process, ATM Vana expert auditors will prepare a detailed inspection report with supporting photos to give you a comprehensive overview and will give all the information and data.

 

During production controls and inspection (DPI), or DUPRO, will provide you some of the benefits can be listed as follows;

• throughout the production process quality and compliance with specifications / standards confirm that you are protected provides.

• If there are any problems that need to be corrected,early detection provides what.

• It contributes to the timely delivery of your projects.

​

c. Initial Production / Product Controls, Initially, control)

​

Initial Production Control (IPC) is on-site Product Inspection of manufactured products and inspection of raw materials and components. All machinery, equipment and materials to be used in production are pre-inspected, the first products produced quality controls, dimensional controls, visual inspections according to the relevant ITP. Initial Production Control (IPC) is the first step in ensuring the quality of your product is consistent throughout production and is an early warning system that protects your product against costly import risks.

ATM Vana uses the internationally accepted standard ANSI/ASQC Z1.4 (ISO 2859-1) statistical sampling standard for Initial Production Control (IPC).

​

d. Factory Acceptance Tests and Inspections (FAT)

​

Factory Acceptance Test (FAT), verifying that the equipment/product is manufactured and functioning in accordance with its design specifications during and/or after the assembly process. It is an evaluation process. As the name suggests, these tests are done at the manufacturers factory.

Factory Acceptance Testing (FAT) is generally performed to evaluate any problems, inconsistencies and nonconformities and develop a process for how to address them. Deviations or nonconformities observed during testing are documented in an inspection report and corrected prior to shipment.

 

During the Factory Acceptance Test (FAT), your products are checked against the specifications and standards listed below. To Inspection & Test Plan (ITP) and in an inspection report together with detailed photographs. We report.

• API 6D Valves Factory Acceptance Tests,

• API 6A Welhead and Tree Equipment Factory Acceptance Tests,

• RMS-A, RMS-B and RMS-C Factory Acceptance Tests,

• Produced according to Botaş specification Valve Groups Factory Acceptance Tests,

• API 5L Pipes Factory Acceptance Tests,

• API 16A Drill Through Equipment Factory Acceptance Tests,

• API 602 Gate, Globe and Check Valves Factory Acceptance Tests,

• API 600 Gate Valves Factory Acceptance Tests,

• Various Pressure Equipments Factory Acceptance Tests,

• TS ISO 17292 and ISO 14141 Tests,

• TS 9809, TS EN 331, TS EN 1983, TS 3148 Tests,

• API 598 Tests,

 

In parallel with these standards and specifications, or additionally, the following tests can be carried out in accordance with ITP;

• functional tests,

• Pressure Tests,

• Hydrostatic Shell and Seat Tests,

• Pneumatic Tests,

• Antistatic Tests,

• Torque Tests,

• Hardness Measurements,

• Thickness Measurements,

• Dimensional and visual controls,

• NDE non-destructive testing report controls,

• Documentation controls

​

e. Pre-Shipment Inspection (PSI - Pre-Shipment Inspection)

​

Pre-shipment inspection (PSI) of randomly selected products from all batches of your order or of all products (100%) when at least 80% of your production is complete or products are ready for shipmentIt is a systematic control. This is the last opportunity to take corrective action before your production is finished and packaged. PSI becomes an effective tool to protect your Product against costly import risks. ATM Vana Pre-Shipment Inspection (PSI). It uses the internationally accepted standard ANSI/ASQC Z1.4 (ISO 2859-1) statistical sampling standard.

A Pre-Shipment Inspection (PSI) by MTA to you that your products have been successfully completed before they are shipped by the manufacturer. Offer a guarantee taste. While the globalizing market of our time presents many opportunities, it also poses great risks. When working with an overseas supplier, it is very important to make sure that the specifications you have actually agreed upon are met.

 

With the ATM Vana pre-shipment inspection (PSI) we have provided some of the benefits. We can list them as follows;

• By taking the necessary precautions, you will reduce the risk of an incorrectly fulfilled order.

• You make sure your order is fulfilled correctly before it leaves.

• You don't have to have the quality checked in the center and pay for the problem products,

• You ensure that the supplier or manufacturer meets all agreed-upon specifications.
