Will a 24 groove small bend deform under high-temperature and high-pressure conditions?

In modern plumbing systems for homes and commercial buildings, the faucet elbow is a key component connecting the angle valve and faucet. Its performance and stability are directly related to the safety and durability of the entire water supply system. Due to its excellent torsional resistance and sealing reliability, the 24 groove small bend has gradually become a mainstream choice for mid- to high-end kitchen and bathroom accessories.1. Material Determines the Basis: The Heat and Pressure Resistance of High-Quality MetalsThe deformation resistance of a 24-groove small bend depends primarily on the material used. The mainstream 24-groove small bend materials currently on the market possess excellent mechanical strength and thermal stability. For example, brass has a melting point exceeding 900°C. Even in hot water environments, which typically do not exceed 90°C in daily water supply systems, its thermal expansion coefficient remains relatively stable, preventing softening or plastic deformation. Stainless steel offers even greater resistance to high temperatures, as well as greater compressive strength and corrosion resistance, making it suitable for more demanding operating conditions. Furthermore, high-quality elbows undergo solution treatment and aging after casting or forging to eliminate internal stresses and enhance material density and structural stability. This process effectively prevents micro-deformation caused by the release of internal stress during temperature cycling, thereby ensuring dimensional stability under long-term high-temperature and high-pressure operation.2. 24-Groove Design: Stress Distribution and Enhanced Connection ReliabilityThe "24-groove" design refers to the 24 evenly distributed grooves or ridges at the interface between the elbow and the angle valve or faucet. These grooves mate with the rubber seal and lock nut for quick connection and non-slip securement. Compared to traditional 12- or 18-groove designs, the 24-groove structure has a higher tooth density, meaning that each groove on the same circumference experiences less torque and pressure, resulting in more uniform stress distribution. Under high-temperature and high-pressure environments, water pipe systems experience thermal expansion and contraction, as well as water hammer, which can cause cyclical stresses at the interface. The 24-groove design effectively distributes these dynamic loads by increasing the number of contact points, avoiding localized stress concentrations and reducing the risk of deformation or loosening due to fatigue. The increased number of grooves also enhances torsional resistance, preventing rotational misalignment caused by minor external forces during installation or use, further improving overall connection stability.3. Sealing System Synergy: Preventing Leaks Due to Micro-DeformationEven if the metal body maintains its shape under high temperature and pressure, a failure in the sealing system can still lead to water leakage. 24-groove small bends are typically used with high-temperature-resistant NBR or EPDM sealing rings. These materials maintain elasticity from -20°C to 120°C and are resistant to aging, hardening, or cracking. When hot water flows through, the rubber ring expands, actually fitting more tightly to the pipe wall, creating a "hotter, tighter" seal. Furthermore, the 24-groove structure, combined with the locknut, ensures uniform axial pressure on the sealing ring, preventing localized leakage caused by uneven or incomplete compression. This integrated design of "structure, material, and sealing" ensures that the small bend maintains a complete connection even under extreme conditions, preventing failure due to minor deformation.Overall, the 24 groove small bend, manufactured with high-quality materials, scientific structure, and rigorous craftsmanship, does not significantly deform under normal household and commercial high-temperature and high-pressure water supply environments. Its design takes into account actual operating conditions such as thermal expansion and contraction, water pressure fluctuations, and mechanical stress, resulting in excellent dimensional stability and connection reliability.
