What is the difference between a tapping sleeve and a tapping saddle?
Saddle taps – the branch line is connected to a main by a corporation stop that is screwed into a metal saddle that wraps around the pipe. Maximum branch line size is 2-inch. Sleeve taps – the branch line is joined to the main via a connection at a metal sleeve that wraps around the pipe.

What is a flange coupling adapter?
Fabricated steel flanged coupling adapter. Provides a quick means of removing and reinstalling flanged fitting already in line. No need for field fabrications, FC ‘s work with plain-end pipe to make the flanged connection. Coupling end helps relieve stress, absorb vibration and accept deflection in the piping system.
What valve is used for hot tapping?
Valve. The valve on a hot tap connection can be either a block valve or a control valve for the new connection, and must allow the coupon (section of pipeline wall cut out by the drilling machine) to be removed after the cutting operation. Suitable valves include a ball or gate valve, but not a plug or butterfly valve.
How hot tapping is done?
Hot tapping, also known as pressure tapping, is a method of connecting (either by drilling or cutting) to a pressurised system, such as a pipeline or pressure vessel, without removing the pipe or tank from service.
What is wet tapping?
Wet tapping is the process of connecting new pipe to an existing pipe installation without having to interrupt the service at any point.

What is a puddle flange?
A puddle or leak control flange is a construction product that connects the waterproofing system to the plumbing drainage system, also known as DWV (Drain Waste Vent).
Is hot tapping safe?
The principal dangers lie in the fact that when hot tapping you don’t depressurize the pipeline and so are dealing with high pressure and/or high temperature situations. Plus, in certain circumstances you have to weld the hot tap machine to the pipeline, there is also a danger of igniting combustible gases or material.
Why do we need hot tapping?
The hot tap procedure involves attaching a branch connection and valve on the outside of an operating pipeline, and then cutting out the pipe-line wall within the branch and removing the wall section through the valve. Hot tapping avoids product loss, methane emissions, and disruption of service to customers.
What precautions should be taken during tapping?
Tapping Safety
- Proper Clothing: The rotating spindle of a machine tool can snag loose fitting clothing, jewelry or long hair.
- Proper Eye Protection: Always wear safety glasses with side shields to protect your eyes from flying particles.
What is dry tapping?
What is Dry Tapping? Dry Tapping is simply tapping into an empty line or pressure vessel. Advantages are shorter lead times, usually a fraction of the cost, less time consuming than traditional bolt-ups and reduces risk of potential leaks by reducing the number of gasketed connections.
What is direct tapping?
Direct tapping involves the tapping of threads into the pipe wall and the insertion of a corporation stop. Generally, a hole is drilled into the pipe when a direct tap is created, and the threads are cut while using the same bit. This process allows for the installation of a corporation stop.
What is hot tapping and cold tapping?
Hot tap / Cold tap is a method of employing an under-pressured drilling machine to provide a branch off pipeline from existing main pipe. This is done via a coring process on the existing operating pipeline without any interruptions to the flow of medium and system.
How does Hot tapping a pipe work?
What is a slip on flange?
Slip on Flange is essentially a ring that is placed over the pipe end, with the flange face extending from the end of the pipe by enough distance to apply a weld bead on the inside diameter. The OD of slip on flange is also welded on the back side of the flange.
Do you waterproof over or under screed?
Do we waterproof above or below the screed? AS 3740-2010 3.2 states: Where a tile bed or screed is used, the waterproof membrane shall be installed above or below the tile bed or screed. Both are correct, and have their various uses.
Do I need puddle flange?
There is another component of the puddle flange which is often overlooked and is required to be installed during slab/substrate preparation, before any waterproofing or screeding takes place. The puddle flange provides the ‘bridge’ connecting the waterproofing from the floor substrate to the drainage pipe.
