Testing Procedures
ある. Dimensional Inspection: Dimension inspection is necessary to ensure that the dimensions of the pipe fittings comply with the specified standards and requirements.
B. Material Testing: We conduct material tests such as chemical analysis, mechanical properties testing, and hardness testing to ensure the quality and integrity of the material.
C.Pressure Testing: We perform hydrostatic or pneumatic pressure testing to verify the structural integrity and leak-tightness of the pipe fittings under specified pressure conditions.
D. Non-Destructive Testing (NDT): Ultrasonic testing, radiographic testing, and magnetic particle testing to detect internal and surface defects without causing damage to the fittings.
E.Visual Inspection: To identify any visible defects, surface irregularities, or imperfections in the pipe fittings we conduct visual inspections.
F.Corrosion Testing: We assess the corrosion resistance of the pipe fittings through methods such as salt spray testing or exposure to corrosive environments

What is 5D Pipe Bends?
5D Pipe Bends are pipe fittings with a bend radius equal to 5 times the nominal diameter of the pipe. These pipe bends are used to change the direction of the pipe, reduce turbulence & increase flow efficiency.
What are Buttweld 5D Pipe Bends used for?
Buttweld 5D Pipe Bends are used in various industries, including oil and gas, petrochemical, and chemical processing, where they are used to redirect the flow of fluids and gases. These pipe bends are ideal for applications that require a smooth flow of fluid or gas and are often used in pipelines, heat exchangers & pressure vessels.
What are the benefits of B16.9 5D Pipe Bends?
The benefits of B16.9 5D Pipe Bends include their ability to reduce turbulence & improve flow efficiency, which results in reduced pressure loss and energy consumption. They also provide excellent strength & durability, making them suitable for high-pressure and high temperature applications. Additionally, their smooth interior surface reduces the risk of corrosion & fouling, which can help extend the pipeline’s lifespan.
