Product Information

The 3'' 304L socket weld coupling class 3000 belongs to the group of high-pressure fittings, where the pipe is inserted into a socket (recess) and welded. The welded socket creates a tight and durable pipeline structure. The Socket Weld (SW) system ensures safety, durability, and a permanent, leak-proof connection.

Socket weld fittings allow easy pressure matching for installations. Each fitting is marked with size, material grade, heat number, and pressure class. All SW fittings are supplied with 3.1 certification.

Advantages:
No need for pipe beveling before welding. Socket weld fittings require minimal preparation and are a reliable alternative to threaded fittings.

Marking:
Each fitting is stamped with size, grade, heat number, and pressure class, sometimes also thread type. Marking complies with applicable standards.

Material Information – 304 / 304L

304 / 304L is a standard stainless steel grade and the most versatile and widely used stainless steel. It offers excellent forming and welding properties and is available in a wide range of products.

Also Known As: 1.4301, 1.4306, 1.4307, AISI 304L
