What else can I help you with?
Can you tell me Difference between pipe schedule 80 and pipe 80?
Schedule 80 means "Pipe Wall Thickness as per Sch.80 of ASME B36.10M". Pipe 80 means "3 inch NPS or 80 mm NB pipe as per ASME B36.10M". Hope that it will answer your query adequately. Regards, Bhatta
What do you mean shedule of pipe?
Schedule of pipe most commonly refers to the thickness of the wall of the pipe itself. ex...schedule 40 PVC pipe has a thinner wall than sch. 80 PVC
What is the pressure rating for schedule 80 steel pipe?
The 80 in 80 steel pipe indicates its wall thickness; the higher the number, the thicker the pipe. The pressure rating for a 5" schedule 80 steel pipe at 100 degrees Fahrenheit is 1857 psig.
How fast is a 1997 Honda cr 125r with a fatty pipe?
About 80-85with a fatty pipe, about 76-80 stock.
When beveling schedule 80 pipe to schedule 40 pipe?
Bevel inside of sch. 80 to match OD of sch. 40
What is the pressure rating for schedule 80 galvanized pipe?
Is this pipe going to be threaded / Grooved or Welded?
What is the recommended fall for foul drainage?
The recommended fall for foul drainage systems is typically between 1:40 to 1:80, meaning a slope of 25mm to 12.5mm per meter (or about 1 to 2 inches per 100 feet). This fall ensures that waste can flow efficiently through the pipes and minimizes the risk of blockages. However, local building codes and regulations should always be consulted for specific requirements.
Sch 80 PVC pipe versus sch 40 PVC pipe?
Yes
What is mean by schedule 80 for Pipes?
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.
What is the pressure rating for schedule 80 pipe?
The pressure rating for schedule 80 pipe is typically around 200 psi (pounds per square inch).
What is the shape factor for schedule 80 pipe?

How do you measure the invert level of a drain?
Pipe Gradients = Above ground and below ground horizontal drainage pipes should be laid to an adequate gradient. = Gradients from 1 in 40 to 1 in 110 will normally give adequate flow velocities. A gradient of 1 in 80 is suitable for commencing calculations for pipe schemes. If a gradient is too steep i.e. steeper than 1 in 40, the liquid may run faster than the solids in the sloping foul water pipe thus leaving the solids stranded, which could then block the pipe. If the gradient is not steep enough, i.e. less than 1 in 110, then the pipe could still block if the solids slow down and become stranded. The fall in a pipe may be defined as the vertical amount by which the pipe drops over a distance. The distance can be between sections of pipe or between manholes. The diagram below show pipe fall and distance. DistanceFallPipeFlow directionA gradient may be defined as fall divided by distance. GRADIENT = FALL / DISTANCE For example is a 24 metre section of drainage pipe has a fall of 0.30 metres, calculate the gradient. Gradient = 0.30 / 24 Gradient = 0.0125 This can be converted into a gradient written as a ratio or 1: some number. Gradient = 1 / 0.0125 = 80 Gradient = 1 in 80 The above formula may be rearranged for Fall if the gradient is known: For example, calculate the fall in a 50 metre section of foul water pipework if the gradient is to be 1 in 80. A gradient of 1 in 80 is converted to a number instead of a ratio. 1 / 80 = 0.0125 Fall = Gradient x Distance = Fall = 0.0125 x 50 = Fall = 0.625 metres or 625mm. The previous diagram may be completed by adding a pipe gradient. DistanceFallPipeFlow directionGradient 1 in 80== The Invert Level of a pipe is the level taken from the bottom of the inside of the pipe as shown below. INVERT LEVEL OF PIPESection through pipeWater levelInvert levelCrown of pipeThe level at the crown of the pipe is the Invert level plus the internal diameter of the pipe plus the pipe wall thickness. It may be necessary to use this in calculations when level measurements are taken from the crown of a pipe. == A manhole or access chamber is required to gain access to a drainage system for un-blocking, cleaning, rodding or inspection. A typical manhole is shown below. Cover and frameBrick wallConcrete baseSloping concrete/mortar bed or haunchingBRICK BUILT MANHOLEPipe channel for access to systemManholes may be manufactured from masonry or precast concrete. Sometimes several precast concrete rings are used to form a manhole which speeds up the on-site construction process. Normally deep manholes below 1.0 metre in depth require step irons to assist access for a workman. Manholes and access chambers are also manufactured in PVC. An access chamber is not usually large enough to admit a person but is suitable for access by cleaning rods or hose and they are used for domestic applications, a common size of plastic access chamber is 450mm diameter. For the domestic market plastic, fibreglass or galvanised steel lids may be used but cast iron lids are required where traffic crosses. A back drop manhole is used in areas where the surface level slopes as shown below. If the undergroung sewer pipe is to stay below ground it must follow the average gradient of the slope. This invariably means that the pipe gradient becomes too steep, resulting in the solids being left stranded in the pipe therefore causing a blockage. To overcome this problem the back drop manhole was developed, as shown below.
