Cut Groove Weldolets Threaded Welded Outlet Q235 Steel Muffs Milling Threaded Coupling for Welding Pipe

Groove-Cutting Design:
The main pipe is cut with a specific groove (e.g., V-shaped or U-shaped) to accommodate the Weldolet, ensuring a precise fit and optimal weld quality.
This design minimizes stress concentrations and enhances the overall integrity of the connection.
Full-Penetration Groove Welding (CJP):
The welding process completely fills the groove, creating a joint that is as strong as the base material.
This ensures the connection can withstand high pressures and temperatures without failure.
Beveled Ends:
Both the run (main pipe) and branch sides of the Weldolet are beveled, facilitating easy alignment and welding.
The bevel angle is typically specified to ensure proper weld penetration and fusion.
Material Compatibility:
Available in a wide range of materials, including carbon steel, stainless steel, and alloy steels, to suit various applications and environmental conditions.
Size and Schedule Versatility:
Offered in numerous sizes and schedules, making them adaptable to different pipe diameters and wall thicknesses.

Preparation: Gather all necessary tools and materials, including the Weldolet, main pipe, welding equipment, and safety gear.
Cutting the Groove: Use a scribe line as a guide to cut a precise groove in the main pipe, ensuring the cut is parallel to the branch pipe axis.
Aligning and Fixing: Place the Weldolet onto the main pipe, using the outer edge as a template to scribe the alignment marks. Tack-weld the Weldolet at four points to secure it in place temporarily.
Welding: Perform a full-penetration groove weld around the Weldolet, completely filling the weld bevel.
Ensure the weld is smooth and free of defects.
Post-Weld Treatment: Clean the weld area to remove any slag or spatter. Conduct a visual inspection and, if necessary, non-destructive testing (NDT) to verify the weld quality.
Pressure Testing: Perform a pressure test to ensure the connection is leak-proof and can withstand the design pressure.

• Enables production of intricate shapes (e.g., hollow structures, multi-way valves).
• Delivers high dimensional accuracy (tolerance ±0.1mm) and smooth surface finish (Ra ≤ 3.2μm).
• Supports diverse stainless steel grades: 304, 316, 316L, etc., for varying corrosion and temperature resistance.

This process is widely applied in Stainless Steel Lost Wax Casting Pipe Fittings, ensuring durability and precision for complex designs.

A refined variant of investment casting using silica sol as a binder, offering superior surface quality and fewer defects (e.g., porosity, sand inclusions).

Ideal for high-end applications like medical devices and food-grade machinery (compliant with ISO 13485, FDA standards). Many Stainless Steel Cast Pipe Fittings are produced using this method to guarantee a smooth finish and enhanced reliability.
