Lap Joint Stub Pipe
|What is a Lap Joint Stub Pipe?|
Lap joint stub end and it associated slip on flange in a piping system allows quick disconnection of the particular section involved. Stub ends are installed in pairs and mated together with two lap joint flanges. The surface of the stub end has a phonographic serrated gasket surface which prevents leakage at the joint
|Advantages of use of Buttweld Fittings|
A piping system using buttweld fittings has many inherent advantages over other forms.
1. Welding a fitting to the pipe means it is permanently leakproof
2. The continuous metal structure formed between pipe and fitting adds strength to the system
3. Smooth inner surface and gradual directional changes reduce pressure losses and turbulence and minimize the action of corrosion and erosion
4. A welded system utilizes a minimum of space
