What is the difference between a service & isolation valve? Service & Isolation valves are an essential part of a bathroom suit. Both valves are available in a straight or bent form and can come rigid or flexible on a short pipe. In the UK, the fittings come in a 15 or 22mm size and varies from country to country. Remember to place a fibre washer in the service valve!
bore of the pipe is the internal diameter of pipe but the nominal diameter of pipe is the dia of a circle which is draw through a point which is situates at exactly half of the thickness of pipe or we can say that (outer dia of pipe- thickness of pipe )=nominal bore of pipe.
They are both the same thread. They are both calling out a British Parallel Pipe thread. Please do not assume that this is the same as the standard North American pipe thread, as it is not close to the same.
No, there is no suitable adhesive. These must both have threaded endings and be mechanically attached or use something like a 'Sharkbite'
GP pipe and GI pipe are both types of galvanized pipes, but they are made in different ways. GP pipe is made by electroplating zinc onto thin sheets of carbon steel, while GI pipe is made by dipping the steel sheets in a molten bath of zinc. GP pipe has a smoother finish than GI pipe, which makes it more resistant to corrosion and rust. However, GP pipe is also more expensive than GI pipe. GI pipe is less expensive than GP pipe, but it is not as resistant to corrosion and rust. GI pipe is also more likely to have a rough finish, which can make it more difficult to clean. Which type of pipe is right for you will depend on your specific needs and budget. If you need a pipe that is highly resistant to corrosion and rust, then GP pipe is the better choice. However, if you are on a budget, then GI pipe is a good option. Here are some additional uses for GP and GI pipes: Water supply: GP and GI pipes are commonly used for water supply lines, both underground and above ground. Drainage: GP and GI pipes are also used for drainage lines, both indoors and outdoors. Plumbing: GP and GI pipes are used for a variety of plumbing applications, such as sewer lines, gas lines, and vent pipes. Construction: GP and GI pipes are also used in construction, such as for rebar cages and formwork.
