PR Valve Seat flatness with 3 light bands
To prevent leakage of the loading fluid, an optical precision on the order of three light beads/bands [0.0000348 in. (0.0008838 mm)] must be maintained in the flatness of seating surfaces on metal-seated pressure relief valves (see API 527).

What is Load test Safety Factor and Proof Test for Lifting devices?
What is the safe working load (SWL)? Safe Working Load (SWL) is the limiting safety factor to lift and carry any load safely. It must be clearly marked on any lifting device (hoist, lifts, lifting machines, and lifting tackles). Marking System of Safe Working Load Lifting equipment should have a tally plate indicating the Safe Working Load. The tally plate also indicates the identification number which can be mentioned in the test certificate held by the user. It should also indicate the date of the last inspection. Safe Working Load ( Or WLL) of different types of sling are given in … Continue reading What is Load test Safety Factor and Proof Test for Lifting devices?

ISO 17025 accredited vs compliant
Compliant or ISO 17025 accredited: Is there a difference? Recently I was having a conversation regarding quality and the often-used phrase came up- ” All things being equal”. This got me thinking when are all things equal? In this particular conversation, it was regarding compliant versus accredited. I don’t think it is immoral, illegal or unethical to use the term compliant when advertising a companies qualifications. That said, there is a significant difference between being compliant and being accredited. Often the term compliant is used when a company offering goods or services is not accredited to the particular standard referenced to … Continue reading ISO 17025 accredited vs compliant
Laboratory ISO 9001 vs ISO 17025
ISO 9001 or ISO 17025: How to choose a calibration company. ISO 17025 or ISO 9001: Which one is better? As a calibration company, we are sometimes asked which is better ISO 9001 or ISO 17025 certification. That really is the wrong question. Both of these International standards are excellent. The reason we said it is the wrong question is that they each have a particular focus. What is the difference between ISO 9001 and ISO 17025? ISO 9001 is a standard designed for the manufacturing and service sector and focuses the Quality Management System towards those major groupings. ISO … Continue reading Laboratory ISO 9001 vs ISO 17025
The project requires Killed Steel treatment on Pipe, Plate MTC.
Fully killed is the term to describe de-oxidized steel. After the steel is made, it is then poured into the continuous caster to make a long slab of steel. Think of a sausage maker – molten steel goes in at the top and rectangular slab comes out the bottom. This is called casting. During casting, small carbon monoxide bubbles can form between the steel grains if the oxygen is not removed. If you’ve ever painted a door and seen bubbles in the paint once you apply it you’ll recognize the similarities. To stop these bubbles appearing you paint slower, but … Continue reading The project requires Killed Steel treatment on Pipe, Plate MTC.
