Frequently Asked Questions
Q: What is the difference between Long Radius (LR) and Short Radius (SR) 180° elbows?
LR elbows have a radius of 1.5 times the nominal diameter, providing lower fluid resistance and better flow. SR elbows have a radius of 1.0 times the diameter, making them ideal for tight spaces where compact installation is critical.
Q: Which material should I choose for a highly corrosive chemical pipeline?
For corrosive media, we recommend Stainless Steel 316L or special alloys like Hastelloy or Titanium, as they provide superior oxidation and chemical resistance compared to carbon steel.
Q: Are your elbows compliant with ASME B16.9 standards?
Yes, all our 180° elbows strictly comply with ASME B16.9 for factory-made wrought steel butt-welding fittings, ensuring international compatibility in dimensions and pressure ratings.
Q: Which connection method is best for high-pressure systems?
Butt Welding (BW) is the preferred choice for medium and high-pressure systems as it creates an integral, seamless structure with the pipe, offering maximum strength and leak prevention.
Q: Can these elbows be used in power plant steam pipelines?
Absolutely. Our Alloy Steel elbows (e.g., WP91, WP22) are specifically designed for high-temperature and high-pressure steam environments, offering excellent creep resistance.
Q: What is the maximum diameter available for 180° elbows?
We provide a wide range of sizes starting from NPS 1/2" up to NPS 48" (DN1200) or larger through our specialized welding process for custom large-diameter requirements.
