Correct installation of steam traps is as crucial as correct selection of steam traps. Many times, it has been observed that correctly selected steam traps often fail due to wrong installation. Installation of steam traps is often not given as much of importance as the steam trap selection which results in lowered operational life of steam traps.

Bimetal traps are not recommended for use on steam mains due to the possibility of large back-up distances which could pool condensate in the steam main itself. This is an especially worrisome situation when the trap is located close to the steam main.

When draining condensate from an elevated steam main using a drip leg, if space is of concern, it is possible to install the trap directly on the vertical section of the trap inlet piping to save space. While the horizontal and vertical setups require virtually the same components, such as a bypass valve with manual valves set before and after the trap, setting the trap at ground level means that greater space is required to install all these components horizontally.

On the other hand, setting the trap on the vertical section of the trap inlet piping does require proper vertical support such as a pipe rack column or pillar for the trap and other piping.

Also, if the trap is not firmly set on the ground, maintenance and repairs can also become more difficult to accomplish, so some method for anchoring to the ground or vertical support is still required. Support is usually not a problem when setting the trap and piping closer to the ground, as the ground can provide support for the installation.

Steam Trap - Ball Float Type - How it works

Repairs and maintenance are also easier to accomplish because components are typically more easily accessible. As each method has its pros and cons, it's important choose the most suitable setup for your particular location.

Best practices for steam trap installation

Installing a trap off a steam main isn't simply about trap selection. There are a number of other factors involved such as proximity to the steam main and space requirements.

It is highly recommended to evaluate trap location and setup before purchasing traps to ensure the safe and efficient transport of steam to the location where it is needed. Proper setups should try to minimize steam loss while allowing for easy maintenance.

Steam traps are used to remove condensate from steam headers, steam . With steam-using plant, the pipe from the condensate connection should fall. Following the article Best Practices for Condensate Removal on Steam Lines, this article aims to offer tips on where to install steam traps on steam mains and. Gravity Drain - In order for the steam trap to drain 1 shows a steam trap hook- up using a separate 'Y' type strainer, The trap can be either maintainable or.

All these factors should be taken into account when deciding the trap setup that will provide the greatest benefits over the long term. Products Browse Products by Category.

Types of Steam Traps

Product Solutions. This is a feature of all balanced pressure traps and explains why they are well suited to air venting. As condensate passes through the balanced pressure steam trap, heat is transferred to the liquid in the capsule.

IMPORTANT: This section is intended to summarize general principles of installation and operation of steam traps, as outlined above. Actual installation and. Correct installation of steam traps is as crucial as correct selection of steam traps. Many times, it has been observed that correctly selected steam traps often fail.

The liquid vaporises before steam reaches the trap. The vapour pressure within the capsule causes it to expand and the Valve shuts. Heat loss from the trap then cools the water surrounding the capsule, the vapour condenses and the capsule contracts, opening the Valve and releasing condensate until steam approaches again and the cycle repeats.

Early bellows type elements of non-ferrous construction were susceptible to damage by waterhammer.

The introduction of stainless steel elements improved reliability considerably. The image below shows an exploded view of a modern balanced pressure steam trap arrangement that has considerable resistance to damage from waterhammer, superheat and corrosion. The differential below steam temperature at which the trap operates is governed by the concentration of the liquid mixture in the capsule.

The 'thin-walled' element gives a rapid response to changes in pressure and temperature. As the name implies, bimetallic steam traps are constructed using two strips of dissimilar metals welded together into one element. The element deflects when heated.

The performance of any steam trap can be measured by its response to the steam saturation curve. Pressure and velocity cannot be relied on to remove the condensate from the process. Determine the steam leak rate of any new steam traps purchased, per the following leak rate standards: PTC ISO All steam traps leak a quantifiable amount of steam and the consumer should be specifying steam traps with the least amount of steam loss to prevent unnecessary energy loss.

Steam traps with 1 in.

steam trap population allows condensate to be removed from the steam system effectively which means . Compact and light weight, reducing installation costs. A steam trap has two major functions: to remove condensate as quickly as it is formed, and to prevent steam discharge. There are certain installation faults which. Plant Engineering - A steam trap has two major functions, to remove condensate as quickly as it forms, and to prevent steam discharge.

Threaded connections are obvious sources of leaks in the system due to expansion, contraction, and corrosion that occurs in a steam system. Some steam component manufacturers have tube connections available for steam trap installations.

Ensure material pressure ratings are acceptable. Piping from the process to the steam trap should always be equal to or larger than the process outlet connection. For example, a steam unit heater with a 1 in. For example, a 1 in. Connect steam traps with connection sizes of 1 in.

The universal mount provides the ability to connect the steam trap to the application with two bolts, thus dramatically reducing installation time.
