Changhao is an expert in weldolet manufacturing. Our precision machinery and state-of-the-art facilities enable us to produce weldments of exceptional quality and dimensional accuracy. We are able to produce a wide range of standard weldments as well as customized weldments according to customer specifications.
Weldolet is a type of branch connection fitting that is typically used where a standard tee is not available or not available. We have a wide range of size combinations in stock. We also produce flat weldments for flat surfaces.
Changhao is a leading manufacturer of elbows, including 45 elbows, 90 elbows and 180 elbows. we ensure 100% best quality and tested products.
The purpose of an elbow is to adjust the direction of flooding in a piping system. Elbows are classified into three major categories in terms of short and long radii - 45 degrees, 90 degrees and 180 degrees. We offer our valued customers a perfectly finished and durable range of butt-weld elbows, which are manufactured from the best standard quality stainless steel in different grades.
The 90 elbow is used for installation between two sections of pipe or tubing, allowing for a 90 directional change.
180 elbow is used for installation between two sections of pipe or tube, allowing a 180-degree change in direction.
Changhao offers elbows in different sizes, materials and grades. Our elbows are available in a wide range of materials such as steel elbows, carbon steel elbows, alloy steel elbows, etc. These special elbows can be customized for our customers based on thickness, size and other factors they require. We also deliver these products as per the sketches provided by the customers.
Changhao manufactures elbows with long service life, while our products are the most economically priced. We have a large customer base in seamless pipe and fittings, which allows us to offer the best discounts to our customers. Our focus is clearly to increase the number of customers and help our customers purchase the best quality goods at the lowest prices. We offer a price guarantee on most of our products, meaning that we can match any price target if reasonably possible.
We produce 45-degree elbow, 90-degree elbow, and 180-degree elbow according to ASTM B16.9/16.5/16.47A/16.47B B2220-2001, SH3408, SH3409, GBT12459, GB/T13401 standards. Our products are widely used in oil and gas, petrochemical, refinery, power plant, shipbuilding, metallurgy, paper making and other industries.
Changhao is a professional manufacturer and supplier of steel pipe caps and pipe fittings. the end cap is mainly used as a plug that covers the end of the pipe. We can supply pipe end caps in standard sizes or according to customers' specifications in accordance with international standards.
Changhao produces various grades of pipe caps including 304/304L, 316/316L, 321, 347, 317L, 310S, 904L, duplex, 201 alloys, 800H alloy, C276 alloy, copper-nickel, 400 alloys, 625 and 600 alloy. Our inventory program includes stainless steel caps and carbon steel caps in standard sizes and grades. Our specialty is providing our customers with caps in a variety of shapes - round, square, rectangular, or other special shapes.
The function of an elbow is to change the direction or flow in a piping system. By default, there are 5 opportunities, 45, 90 and 180 elbows, all three in the long radius version, and 90 and 180 elbows in the short radius version.
Standard: ASTM B16.9/16.5/16.47A/16.47B B2220 2001, SH3408, SH3409,GBT12459, GB/T13401
Production process: Cold extrusion & Hot extrusion forming.
The elbows are divided into two groups which define the distance at which they change direction; the centerline at one end to the other side. This is called the center to face distance and corresponds to the radius of the elbow bend.
The center-to-face distance for long radius elbows, abbreviated LR is always 1.1/2 x Nominal Pipe Size (NPS) (1.1/2D), while the center-to-face distance for short radius elbows, abbreviated SR even is the nominal pipe size.
45 Elbow
A 45 elbow has the same function as a 90 elbow, but the dimensional measurements are different from those of a 90 elbow.
The radius of a 45 elbow is the same as that of a 90 LR (1.1/2D). However, the center-to-face dimension is not equal to the radius in the 90 LR elbow. This is measured from the intersection of each face to the center line perpendicular to each other at a distance of B on the image. this is due to the smaller curvature. Short radius 45 elbows are not available.
