The Principles of Weld Overlay or Metal Cladding

The world of metallurgy involves numerous fascinating and innovative operations in order to add to the productivity and to improve efficiency. Metal cladding or weld overlay is a similar process that is commonly used in several metal working processes. When two or more metals of specific characteristics are applied on a base metal, the process is called weld overlay or cladding. The purpose of the process is to add desirable qualities to the end product or to restore the original dimension of the element.

Factors to Know About Shell and Tube Heat Exchangers

We may be surprised at the fact that heat exchange is a process that we encounter in our everyday life in some form or another. The term simply means that heat is consistently being transferred from one source to another through some medium. The most common examples of heat exchangers can be air conditioners, coolers and heaters, car radiators, refrigerators and so on. From the industry point of view, heat exchangers like condensers and boilers are useful devices that are widely employed for large scale processes. Having undergone multiple improvements and innovations, present-age heat exchangers are considered to be highly efficient and performance-driven. The blog would discuss about a specific type known as shell and tube heat exchangers.

Parameters to Consider Before Choosing a Quality Manufacturer of Cryogenic Vessels

The importance of cryogenic vessels is immense for several industrial sectors and their critical applications. These vessels are known for their strategic ability to contain and store gases like oxygen, nitrogen, argon, hydrogen, helium and carbon dioxide at a pressure that is significantly lower than the ambient pressure. Stored at a temperature as low as 450 degree F, these extremely freezing cryogenic gases can lead to fatal accidents if not handled with care and precision. However, these gases prove to be extremely essential when used for certain high-tech and critical applications. As customers it is mandatory to consider certain deciding factors that assure the efficiency and quality of manufacturers dealing with cryogenic vessels.

Why Didion’s Mechanical is So Good in ASME Pressure Vessels Manufacturing

When it comes to fabricating high pressure vessels, manufacturers are expected to be highly cautious about the aspects and features that govern the functionality, performance, and safety issues of the product. A pressure vessel that carries and transfers elements under substantially high/low pressures should be innately safe and durable. To ensure that the pressure vessels operate with utmost reliability and efficiency, it is important to procure the same from reputed manufacturers with ample years of experience and expertise. But most importantly, you need to make sure that the pressure vessels are compliant with ASME codes and other important stamps like U, U2 and U3 that approve of the safety and security factors of the pressure vessels.

Factors to Consider While Choosing Industrial and Commercial Pressure Vessel Fabrication Services

In industrial terms, a pressure vessel is a strategically constructed container that holds elements (gases, liquids, semi solids) at pressure levels that are considerably different from the ambient pressure levels. As the container is responsible for holding the elements under a critically high/low pressure, it is crucial to fabricate the pressure vessel using the highest engineering expertise in order to avoid even the slightest of fault or loophole, which can lead to fatal consequences. The vital roles played by these pressure vessels for several industrial applications thus call for the requirement of flawless use of pressure vessel fabricators.

How to Select a High Quality Pressure Vessel

Pressure vessel (as the name suggests) is an enclosed container used for storing gases as well as liquids at a certain pressure. We all know the importance of pressure vessel in various industrial as well as domestic applications. However, the long history of fatal accidents related to malfunctioning of pressure vessel has left many skeptic of using it. Well, these doubts can be kept at bay by choosing a high quality pressure vessel.

What is the need for selecting only a high quality pressure vessel?

Well, many of us might wonder that in these economically difficult times, is it necessary to focus on the quality of pressure tanks? Well, the answer is yes, and because of following reasons:

Safety Measures and Guidelines Required to be followed by Pressure Vessel Manufacturers

Pressure vessel manufacturing is a process that needs proper safety measures and precautions. Any disregard to safety can lead to disastrous results. That is why government bodies have released certain guidelines and safeguarding measures to ensure that the process of manufacturing pressure vessels is devoid of any hazards.

Pressure vessel manufacturers are expected to stick of certain codes and guidelines to ensure safety of employees as well as end users. Important codes and standards are:

  • API 572 for Inspection
  • OSHA (Occupational Safety and Health Administration) 1915 Subpart K for vessels, drums, and containers
  • ASME Boiler and Pressure Vessels Code
  • API 510 Vessel Code for maintenance, alteration, and repair

Strip Cladding Methods and Benefits for Industrial Product Manufacturing

Strip cladding is a fusion welding technique where a strip of weld metal is deposited usually within the inner surface of a component. This technique is often employed by pressure vessel manufacturers to achieve a corrosion resistant internal surface when desired by the client. It is also used on a variety of metallic industrial products such as .

clad vessels

Strip cladding is also used to repair eroded or corroded equipment. It is an extremely efficient technique for creating corrosion resistant surfaces. It is particularly useful for protecting vessels made out of low alloy steels, which are prone to corrosion at high temperatures. Cladding can also be performed on flange faces, valves, heat exchanger tube sheets, etc.
