The Hydro Test Procedure for Boilers – How Does It Work?

Boilers form an integral component of several industrial heat generation systems. They provide the steam needed to drive thermal power generation and require strict safety testing to ensure they perform their function correctly. The hydro test is a process that can help manufacturers confirm the integrity of their boilers before routine operation.

What Is A Boiler Hydrostatic Test?

A boiler hydro test is a stress procedure used to determine the integrity of all aspects of a given boiler unit. The test involves filling the boiler with water and pressurizing to at least one and half times the maximum specified operating pressures for a short duration. During this test, if there are any defects in the boiler structure, the test will fail, and the boiler will not pass inspection for routine use.

Why Is It Necessary?

Standard boilers units in use in thermal power plants have multiple welded components, with each weld representing a potential point of weakness that could lead to equipment failure, leaks, and explosions. In addition, boiler hydrostatic testing ensures the boilers can withstand the extreme temperatures and pressures expected during routine operation.

 

Why Is Water Used for Boiler Testing?

In addition to being readily available/cheap to source, water has some physical features that make it ideal for use in boiler pressure testing. Firstly, water is non-toxic and poses no harm to the environment, making compliance with local environmental waste standards easy. Water is also nearly incompressible, making it easy to raise the pressures within a vessel filled with it. In the case of a boiler unit, raising the temperatures from atmospheric pressure to required test levels will be rapidly achieved.

Specific Requirements for Water Used In Boiler Hydrostatic Tests

For optimal testing results, water introduced into a boiler for testing should be maintained between 86°F and 122°F. Additional desirable parameters include:

  • pH range of 8.5 – 9.2
  • Silica 0.02 ppm
  • Conductivity between 5-10 mic S/cm
  • Water hardness of zero

Boiler Pressure Testing Procedure and Requirements

The requirements for a boiler pressure test include the following:

  • A high-pressure displacement pump
  • Properly calibrated pressure gauges
  • Pressure bleed valves

To begin the test, the pressure displacement pump is connected to the boiler with an integrated gauge. Next, the boiler is rapidly filled with water with care taken to displace any air pockets within the vessel. The pressure within the boiler should be raised to 1.5 times the standard operating pressures and held at this level for at least 30 minutes by closing all bleed valves.

After holding the pressure at elevated levels, it should be reduced to normal operating pressures, and the boiler is then inspected for any leaks/wetting or defects. Once the inspection is done, the pressure within the boiler is further reduced to atmospheric levels, and the water is drained. The boiler hydro test must be witnessed by inspection officials who confirm the absence of leaks and then certify the boiler accordingly.

How Often Is Boiler Hydrostatic Testing Required?

The frequency of boiler pressure testing varies between locations and mainly depends on assessing various boiler criteria, including age, pressure requirements, and operating history. For the most accurate confirmation of testing frequency for your boiler units,  In version 2022 of Bangladesh Boiler Act. Need two times in a year (one time Must). Also you should contact the local or state inspectors in charge of your area of operation.

M&S Plan-A Our Planet 

We know M&S launched Plan A, for our sustainability action plan, in 2007 – because they knew there is no Plan B when it comes to our planet. That’s why they have reset Plan A on our mission to become a net zero business across our entire value chain by 2040. Net zero means simply that we don’t add any more greenhouse emissions to the atmosphere than we take out of it.

Most of the company management don’t know how to face the Plan-A audit. So ultimately they are failing to archived the M&S Plan-A certification.  

Now we are consulting and helping your company, how to prepared your company and which point’s need to focused. We have experience person (Plan-A Achiever) to guide you and support you how to implementing your project as required for Plan-A Certification. We can save your time, money and get customer satisfaction.

For Plan-A Certification, needs to focused on bellow listed Point-

Energy saving 2. Reduced Carbon Footprint 3. Compressed air  4. Smart Lighting 5. Smart Temperature control 6. Water Saving 8. Zero Wastage 9 . Eco Factory Policy with Environment certification. 

Higg. Index

The Higg Facility Environmental Module (Higg FEM) is a sustainability assessment tool that standardizes how facilities measure and evaluate their environmental performance, year over year.

The Higg FEM informs brands, retailers, and manufacturers about the environmental sustainability performance of their individual facilities, so they can make improvements that reduce negative sustainability impacts.

The Higg FEM assesses   

  • Environmental management system
  • Energy use
  • Greenhouse gas emissions
  • Water use
  • Wastewater
  • Emissions to air (if applicable)
  • Waste management
  • Chemical use and management

Industry Sectors

We provide consultancy and verification of Higg FEM for the following industry sectors:

  • Textile
  • Apparel
  • Footwear

What Classic Industrial Service BD can offer
Verification/ Certification for each year

Control Union is a Verification Body approved by Sustainable Apparel Coalition (SAC) to offer on-site verification of Higg FEM as per the SAC verification protocol and procedures for textile and apparel facilities to communicate credible Higg Index FEM claims.

How you benefit from us

The Low Carbon Manufacturing Programme (LCMP)

WHY LCMP?

We know by providing manufacturers with a tool to measure carbon emissions and to help them strive towards best practice, the LCMP ensures low-carbon manufacturing practices are properly learned and implemented along the supply chain, which is in line with mainland China’s national energy saving plan and carbon emissions reduction target.

The Low Carbon Manufacturing Programme (LCMP) aims to cut carbon emissions generated by manufacturing facilities and develop environmental social governance for manufacturers. By providing manufacturers with a carbon accounting and labeling system, LCMP helps to measure their effectiveness in reducing carbon emissions and equip them with best practices in greenhouse gas management.

Recognizing the significant potential for both energy and cost saving in manufacturing, with generous sponsorship from the Green Dragon Fund, WWF Hong Kong has developed the LCMP with two renowned technical consultants – Hong Kong Productivity Council and Azure International Technology & Development (Beijing) Ltd.

Most of the company management don’t know how to face the LCMP audit. So ultimately they are failing to archived the LCMP Score.
