WHITE STEEL PIPE ELBOW
White Steel elbow includes stainless steel elbow(ss elbow), super duplex stainless elbow and nickel alloy steel elbow.
ELBOW TYPE
Elbow could be ranged from direction angle, connection types, length and radius, material types, equal elbow or reducing elbow.
45/60/90/180 Degree Elbow
As we know, according to fluid direction of the pipelines, elbow can be divided into different degrees, such as 45 degree, 90 degree,180 degree, which are most common degrees. Also there has 60 degree and 120 degree, for some special pipelines.
What is Elbow Radius
The elbow radius mean curvature radius. If the radius is the same as pipe diameter, it called short radius elbow, also called SR elbow, normally for low pressure and low speed pipelines.
If the radius is larger than pipe diameter, R ≥ 1.5 Diameter, then we call it a long radius elbow (LR Elbow), applied for high pressure and high flow rate pipelines.

DETAILED PHOTOS
1. Bevel end as per ANSI B16.25.
2. Rough polish first before sand rolling, then the surface will be much smooth.
3. Without lamination and cracks.
4. Without any weld repairs.
5. Surface treatment can be pickled, sand rolling, matt finished, mirror polished. For sure, the price is different. For your reference, sand rolling surface is the most popular. The price for sand roll is suitable for most clients.

Frequently Asked Questions:
1. What is the difference between 304 and 304L stainless steel?
- 304 stainless steel contains higher levels of chromium and nickel than 304L. This makes 304L more resistant to corrosion, especially where welding is involved.
2. What are the main properties of 321 stainless steel?
- 321 stainless steel has excellent high temperature resistance, up to 1500°F (816°C). It also has good creep and stress rupture properties, making it suitable for applications where high temperatures are encountered.
3. Can 316 stainless steel be used in marine environments?
- Yes, 316 stainless steel is widely used in marine applications due to its excellent corrosion resistance, especially to salt water and various chemicals commonly found in marine environments.
4. What is the difference between 316L stainless steel and 316?
- The carbon content of 316L stainless steel is lower than that of 316, which enhances its welding ability and eliminates the risk of carbide precipitation during the welding process. This makes 316L ideal for applications requiring welding.
5. What is the significance of "90-degree butt welded pipe elbow"?
- 90 degree butt weld elbow is a pipe fitting used to change the direction of fluid flow at a right angle. It is designed to be welded directly to pipes, creating a strong and leak-proof connection.
6. What are the benefits of using stainless steel elbows?
- Stainless steel elbow has excellent corrosion resistance, high strength and durability. They also provide smooth flow paths for fluids and are resistant to high temperatures, making them suitable for use in a variety of industries.
7. Can stainless steel elbows be used for both gas and liquid applications?
- Yes, stainless steel elbows are available for gas and liquid applications. Stainless steel is versatile and can handle a variety of fluids, including gases, liquids and corrosives.
8. What is the common size range of stainless steel pipe elbows?
- Common size ranges for stainless steel elbows vary based on specific applications and industry requirements. However, typical sizes for these elbows range from 1/2 inch to 24 inches in diameter.
9. Are stainless steel elbows suitable for high pressure applications?
- Yes, stainless steel elbows are often used in high pressure applications due to their superior strength and corrosion resistance. However, the correct choice of elbow wall thickness and material grade is critical to ensuring safe operation under high pressures.
10. Can 90-degree butt welding elbow be used in a small space?
- Yes, 90 degree butt weld elbows can be used in tight spaces as they can change direction without the need for additional fittings. However, it is important to consider the available clearance for installation and maintenance purposes.
