Introduction
In today’s market, various types of water pipes exist, broadly classified into plastic pipes (made of plastic) and metal pipes (consisting of metal products). Among metal pipes, thin-walled stainless steel water pipes stand out, typically connected using crimping. But what makes one type of pipe fittings better than another? Quality pipe fittings ensure higher safety for long-term water supply or other gas and liquid pipelines. Let’s delve into why PEX Press Fittings are the optimal choice.
Understanding PEX Press Fittings
The fundamental principle behind stainless steel crimp fittings lies in their unique pipe joint components, featuring U-shaped grooves at the ends with O-ring seals. During assembly, stainless steel water pipes are inserted into the fittings, and a specialized crimping tool is used for sealing. The crimped portion of the fitting and the pipe are compressed into a hexagonal shape, thus forming sufficient connection strength. Simultaneously, the compression deformation of the sealing ring ensures reliable sealing.
Characteristics of PEX Press Fittings
- Long Service Life: Stainless steel water pipes boast a lifespan of over 50 years, meeting national, Japanese, European, and other international drinking water standards. This implies that stainless steel water pipes can be used long-term without aging or corrosion issues.
- Hygienic and Eco-Friendly: Stainless steel is a non-toxic, tasteless, and pollution-free material that does not release harmful substances, ensuring the safety of drinking water and compliance with hygiene standards.
- Corrosion Resistance: Stainless steel exhibits excellent corrosion resistance, resisting the erosion of oxidants, acids, and alkalis in water. This means stainless steel water pipes will not corrode or leak during use, maintaining pipeline integrity.
- Convenient Installation: Stainless steel crimp fittings adapt to harsh environments without the need for on-site threading or welding. Installation time is only one-fourth that of galvanized pipe fittings. Whether in confined pipeline shafts or waterlogged trenches, crimp fittings offer flexible and rapid connections, shortening construction periods and reducing costs.
- Impact Resistance and Thermal Conductivity: Stainless steel water pipes have twice the strength of galvanized steel pipes and three times that of copper pipes, with high joint strength. Additionally, stainless steel’s thermal conductivity is only 1/25 that of copper pipes and 1/4 that of steel pipes, exhibiting slow thermal expansion and contraction characteristics, suitable for temperature changes and impact loads.
- Material Savings: With a thin-wall design, stainless steel water pipes weigh only one-third of galvanized pipes, significantly saving materials and reducing product weight. This is particularly beneficial for piping in high-rise buildings, reducing structural loads.
- Aesthetic Appeal: Stainless steel water pipes have an attractive appearance that matches both new installations and environments after prolonged use. The inner walls of the joints are smooth and unobstructed, with the product interface being the same diameter as the water pipe, resulting in minimal water resistance.
Construction Considerations for Stainless Steel Crimp Fittings
- Handle with Care: Avoid damaging fittings during operations. Pay attention to avoiding rough operations such as trampling on fittings at the site.
- Storage: When storing pipe materials, avoid direct sunlight and cover them with plastic straps or security blankets for protection.
- Cleanliness: Ensure fittings are clean, especially at the pipe ends and rubber seal positions, promptly dealing with oil and foreign matter to prevent more severe consequences.
- Deburring: Check whether burrs at the pipe ends are cleaned, especially internal burrs, to ensure the joint between fittings and pipes is secure.
- Installation: After inserting fittings, tighten threads first before crimping to prevent loosening due to thread rotation after crimping.
- Pipe Bending: If pipe bends are incorrect, correct them in straight pipe sections rather than at fitting sections to avoid leaks.
- Re-Crimping: If loosening occurs at crimping points, re-crimp at the original crimping points (pay attention to the correct hexagonal direction).
- Compatibility: Contact the manufacturer when using other media (such as oils, chemicals, or gas) to prevent rubber seal damage due to media corrosion.
- Corrosion Prevention: Consider anti-corrosion measures when using near the coast or in areas with high salt content. Special attention should be paid when using for well water, seawater, hot spring water, or fluids with high salt content.
- Water Quality: Consider the impact on piping when using untreated well water for heating water.
Conclusion
PEX Press Fittings, as a new type of pipe connection method, offer numerous advantages. They feature a long service life, hygienic properties, corrosion resistance, convenient installation, impact resistance, thermal conductivity, material savings, and aesthetic appeal. While attention to construction details is necessary during use, proper usage and maintenance ensure pipeline safety, reliability, and durability. Therefore, PEX Press Fittings are a novel pipe connection method worth promoting and using.
