Regardless of whether the system is residential, commercial, or industrial, pressure pipe fittings always have a part to play in ensuring the safety, durability, and longevity of plumbing systems. But even the best fittings on the market won’t be able to do their job if they aren’t installed correctly. From improper measurement to misalignments, we at Convic will be using this post to take a look at some of the most common mistakes involving pressure pipe fittings you would want to watch out for in your next plumbing project.
What are pressure pipe fittings, and what is their purpose?
Pressure pipe fittings are specialized components that are used to ensure proper connections and maintain the structural integrity of systems that transport compressed liquids and gases at high pressure. The range of pressure pipe fittings currently available in the market can be categorized into three core groups. They are:
- Low- to medium-high-pressure pipe fittings (1000 – 6000 PSI)
- High-pressure pipe fittings (6000 – 10,000 PSI)
- Ultra-high-pressure pipe fittings (10,000 – 15,000 PSI)
These components are characterized by their robust construction and enhanced sealing capability. These are essential features considering that they serve a wide range of purposes, such as
- Ensuring proper connectivity in high-pressure systems;
- Preventing leakage in high-pressure systems; and
- Helping maintain the structural integrity of the system
Common errors made with pressure pipe fittings
Errors in Measurements
One of the most common mistakes associated with pressure pipe fittings is errors in measurements. When the fittings are mismatched, it can lead to leaks and reduced structural integrity in the system. To avoid problems manifesting in the future, invest time to take accurate measurements and ensure that your pipe fittings are the correct size for the job.
Errors in Material Selection
Pressure pipe fittings are made with numerous materials, such as copper, galvanized steel, PVC, and PEX, to name a few. Selecting the right material is crucial for addressing concerns of durability, corrosion, and cost-effectiveness and ensuring the long-term stability of the system.
What may be the right material for the system will depend on your specific requirements. Therefore, take a moment to carefully assess your objectives and priorities and purchase fittings made from materials that best meet your objectives. If you’re unsure as to what can be considered the right material, contact a professional and get their advice on the matter.
Disregarding the contraction and expansion of components
When the system is exposed to environmental factors such as changes in temperature and pressure, the pipes and pipe fittings contract and expand. Therefore, it is important to ensure that there is enough space for the size variations in the system. If you have not properly accounted for this during the installation, the stress can cause leaks and cracks, leading to structural failure.
Overtightening and undertightening
Properly tightening your pipe fittings is essential to ensure that your system remains stable and performs optimally. To avoid the issues that come with over-tightening and under-tightening of fittings, use the correct tools and stop tightening your fittings when you achieve a snug fit.
Neglecting to use tapes or sealants
An additional, often overlooked step when it comes to ensuring a proper seal with pressure fittings is the use of tapes and thread sealants. These add an extra layer of protection and help to increase the structural integrity of the system. Different products have different use case scenarios, so make sure to read the manufacturer’s instructions.
Conclusion
Pressure pipe fittings play an important role in the overall integrity and longevity of your plumbing systems. From selecting the correct sizes to materials and beyond, each step taken to avoid the mistakes involving pressure pipe fittings can prevent costly mistakes and headaches later down the line.
