What is the clearance around a zero clearance fireplace flue pipe inside of the surround that you build assuming it is double wall or type L since there is a gas log in the old surround.
Thicker pipe wall is required to contain higher fluid pressures. For the same fluid pressure, a thicker pipe wall is required for a larger diameter pipe than that required for a pipe of smaller diameter. A schedule of pipe sizes and wall thicknesses has been established by ASTM standards governing manufacturing of pipe. A previous description of pipe wall thicknesses as "Standard", "Extra Strong" and "Double Extra Strong" has been supplanted by a schedule of 10, 20, 30, 40 60, 80, 100, 120 and 160. Schedule 40 pipe generally compares with the previous use of "Standard". For metal pipe, Schedule 80 pipe has a thicker wall and can withstand greater pressures than a Sch 40 pipe. A point of confusion is that for PVC piping, Schedule 80 pipe has a thinner wall than Sch 40 pipe.
there are many ways to prevent heat loss in your house including; loft insulation, double or triple glazed windows, installing pipe covers on exposed water pipes, purchasing a boiler jacket and even special wall insulation. i hope this advice helps you.
its the thickness of the pipe wall
the wall thickness of sch 40 - 500mm dia pipe is 15mm or 16mm.
It refers to the strength and wall thickness of the pipe.
The male end should point up or out. So the female end fits on the stove and thereafter the male end terminates the run.
Double Wall Corrugated Pipe.
I think there are two types of stove pipes. 1) Double Wall Stove Pipe 2) Single Wall Stove Pipe
A twin wall flue is a stainless steel flue surrounded by an inch of insulation with an outer skin of stainless steel. A twin wall flue allows you have a real fire without a brick built chimney.
Directly relates to vent piping on gas appliances. Single wall means one pipe,as compared to two wall piping, a pipe inside a pipe. The reason being an air gap between the two walls acts as an insulator to prevent the hot flue gasses from burning the touch or combustable materials.

If the installer used CHEAP single wall flue pipe (sheet metal) and the heater is running for an extended amount of time YES it gets very hot and double wall piping should be used when passing through any flammable area AGA , NFPA 54
If it is an 80% efficient, non condensing furnace, No. The flue gases are too hot and will melt the pipe and pose a fire hazard where it passes thru the house wall.
Not only is it wrong to use on single wall pipe but is ABSOLUTELY WRONG,WRONG to use single wall pipe!!! replace immediately w/double wall pipe. You have an extremely dangerous fire hazard! almost any gas fueled device produces exhaust which can get extremely hot. A secondary benefit(besides not turning into a crispy critter) of using properly installed double walled pipe is no need to wrap w/insulation.

Heavy Wall pipe refers to a steel pipe has a wall thickness of relatively thick. by SunnySteel.com
As long as the pipe going into the wall is straight, the rest of the drain pipe can be routed however it needs to be. Very often the trap is at an angle to the pipe in the wall.
