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.

Classification by Material

Let us introduce some competitive materials we offer here:

Stainless steel elbow: Sus 304 sch10 elbow, 316L 304 Elbow 90 degree long radius elbow, 904L short elbow

Alloy steel elbow: Hastelloy C 276 Elbow, alloy 20 short elbow

Super duplex steel elbow:Uns31803 Duplex Stainless Steel 180 Degree Elbow

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.

INSPECTION

1. Dimension measurements, all within standard tolerance.

2. Thickness tolerance:+/-12.5% , or on your request.

3. PMI

4. PT, UT,X-ray test

5. Accept Third party inspection.

6. Supply MTC, EN10204 3.1/3.2 certificate, NACE.
