ASTM A234 WPB Custom Butt Weld Elbows | 90 & 180 Degree

zhao77jie — Mon, 09 Feb 2026 03:30:42 +0000

On 8^th December 2025, we once again received message from one of our regular customers. The customer has ordered several batches of elbows during past years. This time the client required some replenishment of 90 and 180 deg elbows as the same specification of last order. Thus we double-checked client’s drawings and ASME B16.9 standard and took notes of what the client paid more attention to. One week later, we arranged manufacturing as per client’s request. Since the elbows are produced based on client’s drawings, we offered detailed inspection photos for them before shipment.

What Custom WPB Butt Weld Elbow refers?

ASTM A234 WPB custom BW elbow is a carbon steel pipe fitting tailored for pipeline direction changes, complying with ASME B16.9 standards. Made of high-quality ASTM A234 WPB carbon steel, it features excellent weldability and pressure resistance, suitable for custom 90 & 180 degree angles, radius, and wall thickness. This fitting is widely used in oil, gas, and petrochemical pipelines with beveled ends for seamless butt welding and stable structural performance under high-temperature and high-pressure working conditions.

Why Choose ASTM A234 WPB

ASTM A234 WPB is the first choice for custom butt weld elbows (90 & 180 degree) due to its superior comprehensive performance. This carbon steel material features excellent weldability, formability, and medium pressure resistance—suitable for various custom forming processes. It also offers cost advantages over alloy steel, with wide availability and mature manufacturing technology. For industrial pipelines requiring custom angles and specifications, ASTM A234 WPB balances performance, customization, and economic efficiency perfectly.

90 Degree vs 180 Degree

90 and 180 degree elbows are the two most common custom angles, both manufactured to ASME B16.9 dimensional tolerances. The 90 degree elbow is for 90° pipeline turns, ideal for tight space layouts. While the 180 degree elbow (U-bend) suits pipeline reverse direction needs. All fittings retain ASTM A234 WPB core properties: good corrosion resistance and weld strength, with customizable long/short radius for different flow rate requirements in industrial pipelines.

Custom Specifications of Elbows

Our ASTM A234 WPB custom butt weld elbows support full specification customization under ASME B16.9 standards, covering DN15-DN1200 caliber, Sch40/Sch80 wall thickness, and 90/180 degree angles. We also customize beveled end size, length, and surface treatment (e.g., anti-rust painting) based on customer requirements. All custom parameters are designed to match ASTM A234 WPB weldability and mechanical properties, ensuring the fitting integrates perfectly with existing carbon steel pipeline systems.

Core Advantages of Custom Elbows

ASTM A234 WPB custom butt weld elbows combine the core advantages of WPB material and personalized customization. Key benefits include excellent weldability, high pressure/corrosion resistance. And it perfectly match with customer pipeline layouts via 90/180 degree, radius, and thickness customization. The seamless hot forming process ensures structural stability, while the carbon steel material offers cost-effectiveness and wide industrial applicability.

Application Scenarios

ASTM A234 WPB 90/180 degree butt weld elbows are widely used in industrial pipeline systems globally, mainly in oil and gas exploration/transmission, petrochemical refineries, power generation plants, and water treatment projects. They are suitable for medium-temperature and medium-high pressure pipelines transporting oil, gas, water, and other non-corrosive media. The custom angle and radius design make them adaptable to complex pipeline layouts. Meanwhile, material performance of ASTM A234 WPB ensures long-term stable operation.

How to Customize Your Butt Weld Elbow?

Customizing butt weld elbows (90/180 degree) is a simple, standardized process, with all products manufactured to ASME B16.9 standards.

First, provide your core requirements: angle (90/180°), radius (long/short), caliber (DN), wall thickness (Sch40/Sch80), and application conditions.

Second, engineer confirms the custom design and provides a technical drawing for your approval.

Finally, we start production exactly based on your drawings, conduct strict quality inspection, and deliver the finished product with a full quality certificate—supporting one-stop custom fitting solutions.

180 Degree Elbow Order From Bolivia

zhao77jie — Thu, 22 Aug 2024 08:03:11 +0000

On 23, April, we received an inquiry from Bolivia. This client sought for 400 pieces carbon steel 180 degree elbow in carbon steel with simple drawing attached.

180 Degree elbow is our products. Thus we offered our competitive quotation based on the drawing. Two months later, the customer showed us more accurate drawing, together with many photos showing the details of the elbow that they wanted. We inspected all the information offered updated quotation fulfilling customer’s requirements.

After reviewing our quotation, the client placed the order. And after reviewing our sample, we manufactured in quantity.

We took very detailed photos of the sample to make sure that’s what our client want.

What is 180 Degree Elbow

180 Degree elbow is a pipe fitting that bends the pipeline by 180 degrees. It is used when a large directional change is needed or when a pipeline needs to be reversed without creating back flow.

According to the bending radius, 180 degree elbow will be divided two types, which are long radius (LR) and short radius (SR). As the weld type, there are seamless are welded elbow. Usually, seamless butt weld elbow is more expensive than welded due to the good property.

Dimension of ASME B16.9 180 Degree Elbow

ASME B 16.9 is set by the American Society of Mechanical Engineers. This standard governs scope, pressure ratings, size, marking, material, fitting dimensions, surface contours, end preparation, design proof tests, production tests, and tolerances.

180 Degree elbow produced according to ASME B16.9 have a wide range of sizes ranging 1/2 to 24. Common wall thickness pressure levels include Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS, etc. Among them, the most commonly used are STD and XS.
