Frequently Asked Questions

What is the difference between long radius and short radius elbow fittings?
It is the long radius elbow fittings that have a longer curvature, thus giving smoother fl ow and minimized pressure drop. Short radius elbow fittings provide a smaller curvature radius and hence compactness but can lead to higher pressure drops.
What is the maximum pressure rating for stainless steel butt-welded elbow pipe fittings?
However, the maximum pressure rating relies on material grade, fitting size and design. It is always necessary to follow the manufacturer’s specifications and standards of industry for these particular pressure ratings.
Can stainless steel butt-welded elbow pipe fittings be used in high-temperature applications?
The answer is yes because stainless steel butt-welded elbow pipe fittings can resist high temperatures. The temperature specifications, however, may be dependent on the material grade and its use. It is therefore important to take into account the temperature restrictions from the manufacturer and refer back to industry standards.
