Buttweld fittings are a type of pipe fittings used to connect pipes of various materials by welding. They are designed to provide a smooth transition in the piping system while ensuring a leak-proof and strong joint. Here's an overview of Buttweld fittings including materials, features, applications, and advantages:

Common Materials used for Buttweld Fittings:

Buttweld fittings are available in various materials to suit different applications. Some common materials include:

Stainless Steel: Stainless steel Buttweld fittings are widely used in industries such as chemical processing, oil and gas, food processing, and pharmaceuticals due to their corrosion resistance and durability.

Nickel Alloys: Nickel alloy Buttweld fittings offer excellent resistance to corrosion and high temperatures, making them suitable for applications in chemical processing, petrochemical, and power generation industries.

Copper Alloys: Copper alloy Buttweld fittings are often used in plumbing systems and HVAC applications due to their excellent thermal conductivity and corrosion resistance.

Aluminium Alloys: Aluminium alloy Buttweld fittings are lightweight and offer good corrosion resistance, making them suitable for applications in industries such as aerospace, automotive, and marine.

Titanium Alloy: Titanium alloy Buttweld fittings are known for their high strength-to-weight ratio and corrosion resistance, making them suitable for use in chemical processing, aerospace, and marine applications.

Manufacturing Process Of Plate


Using a forging machine to lower the outside diameter and bevel the pipe end or extension is one method of making forged fittings.

Rolling Wheel

The core is inserted into the pipe using butt weld fittings. After that, processing the rim and pushing the exterior with a roller.


Expand the pipe end in the punching machine to the desired size and shape by using a tapered core.


for creating bend and elbow fits. There are three typical approaches. There are three or four rollers: one is for stretching, one for stamping, and the third is for rolling.


A rubber is inserted into the tube and compressed with a punch, causing the pipe to bulge; hydraulic bulging forming is an additional technique.
