Latrolet Types
Socket Weld Latrolet : This type of Latrolet is typically used for smaller pipes. It features a socket into which the branch pipe is inserted and then welded using a fillet weld. This connection is strong and reliable, suitable for high-pressure and high-vibration environments.
Threaded Latrolet : The outlet of a threaded Latrolet is internally threaded and connected to the branch pipe via a threaded connection. This connection offers the advantage of easy installation and removal, but its sealing performance is weaker than that of a butt weld. It is typically used for medium- and low-pressure, small-sized piping systems.
Butt Weld Latrolet : The outlet of a butt weld Latrolet is beveled, allowing for direct butt welding to the branch pipe. This connection offers the highest strength and best sealing performance, making it suitable for critical piping systems of various sizes, high pressures, and high temperatures.

Olet Pipe Fittings
We marked all Forged Fittings with Grade, Lot No, Size, Standard and Pressure. The workers surfaced all 8″ x 3″ Olet Pipe Fittings with anti-rust oil, sleeved them into plastic bag individually, then packed them in carton and wooden cases, finally bundled packages with nylon rope.
Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. great care is taken during operation and transportation.
Inspection
- Visual the surface of carbon steel outlet body. Such as dents, die marks, porosity, undercuts etc.
- Check the marking. Such as Size, Material Code, Grade, Thickness, Heat No.
- Measure dimensions of latrolet. Such as diameter, wall thickness, and end to end length.
Advantages
- Good Quality
- Fast Delivery
- Safe Package
- Abundant Stock
- Reasonable Price
- Reliable Shipment
