Pressure Safety Valve Calibration, Maintenance

Amarine Antonio

A Simple Pressure Safety Valve Calibration Procedure One of the simplest but most important instruments that I encounter which are used not for displaying or monitoring the process, but for safety, it is the pressure safety valves. When I was just starting out as a cal tech, looking at it installed in a tank makes me curious about its usage. You cannot see any actions or output display as a sign of its operation. In this post, I will present the following: What is a safety valve? Its difference with a relief valve Why do we need to calibrate a … Continue reading Pressure Safety Valve Calibration, Maintenance

Can ASTM material use for ASME application.

Amarine Antonio

Under ASME, ASTM materials are NOT automatically accepted. SA designated material should be used at all time ( NOT ASTM A designation), with following exception from Interpretation VIII-1-92-74: Hence, the inspector MUST verify that the Year edition of the ASTM specification detailed on material certification is accepted by the specified edition of ASME code section II, Part A. ASME II Part A details which  ASTM editions for each material are equivalent to ASME SA grade as below extract: Example: ASTM A-36 (2005) is identical to ASME SA-36 (ed. 2007/2008 add) Meanwhile,  the ASTM A737 material is confirmed to be compliant … Continue reading Can ASTM material use for ASME application.

FITTING PRESSURE RATING

Amarine Antonio

To be continued from this chapter “Pipe pressure rating“, I’d like to introduce to you about the fitting pressure rating. Note: Flanges, Gaskets, Valves, Weld fittings are designed as CLASS Typically, there’re three type of Fitting CLASS rating: According to ASME B16.5, are made in seven primary Pressure Classes: 150 300 400 600 900 1500 2500 The concept of flange ratings likes clearly. A Class 300 flange can handle more pressure than a Class 150 flange, because a Class 300 flange are constructed with more metal and can withstand more pressure. However, there are a number of factors that can … Continue reading FITTING PRESSURE RATING

PIPE PRESSURE RATING

Amarine Antonio

Pressure and temperature ratings take into account function and price to help our customers easily select the most suitable pipe, fittings, valves for their work. The pressure and temperature ratings refer to the relation between the fluid temperature and the maximum pressure each piping component can withstand at that temperature. Products are grouped by material, and each is shown with its rating. Note: Pipe is designed as Thickness and Schedule, there’s no any standard pressure rating for particular pipe but the Calculation guideline.  There are two way to select the pipe which can withstand the maximum working pressure of system. Solution … Continue reading PIPE PRESSURE RATING

Pressure Vessel RBI – intro

Amarine Antonio

RISK-BASED INSPECTION Risk-Based Inspection (RBI) ensures you are performing the right inspections (procedure), on the right assets, in the right areas, at the right frequency. With thousands of assets to monitor, it can be challenging to properly prioritize inspection investments in efforts to reduce loss of containment risks to acceptable levels. Whether dealing with pressure vessels, pressure relief devices, piping segments, pipelines, check valves, or pump casings, loss of containment risks should be identified and mitigated before they happen. Risk-Based Inspection (RBI) can help these risks be proactively mitigated. RBI is an approach used to assign risk to particular assets within … Continue reading Pressure Vessel RBI – intro

How to view the material certificate? – Part 3 ( Final part )

Thanh ( QC ) Nguyen Le

Continue:  PART 3  – Fake certificate: Why have the FAKE CERT? The Certified Mill Test Report is a tool used to ensure that received raw material matches the engineering and purchase order requirements. There are clear requirements for what should go on the certificate but every so often someone tries to produce a fake mill certificate to sell steel plates fraudulently. 2. How to identify a FAKE STEEL MTCS? A fake mill certificate is normally fairly easy to spot if you know what you are looking for. You can sent them an email asking to vendor to clarify this certificate. … Continue reading How to view the material certificate? – Part 3 ( Final part )

How to view the material certificate? – Part 2

Thanh ( QC ) Nguyen Le

Continue:  PART 2 – How to view the certificate??? We will take example for Mill cert’, other cert’ is same procedure. Mill cert:  A Certified Mill Test Report (CMTR) is a quality assurance document generated by the raw material manufacturer and provided with the material to intermediate suppliers and ultimately to a finished goods manufacturer. Whether it’s called a CMTR, Mill Test Report (MTR), Mill Certification, Metallurgical Test Report, or similar name, this document provides the end user of the raw material verification that the material received matches the requirements of their order. CMTRs are also used to maintain traceability … Continue reading How to view the material certificate? – Part 2
