Weight

Light

Heavy

Heavy

Very Heavy

Very light weight therefore easy in shifting & convention in jointing

Surface

Very Smooth

Rough

Light Rough

Rough

Smooth surface gives 25 % more flow therefore smaller diameter pipe can be used. Thus economical

Length

6 meter

5 to 6 meter

3 to 4 meter

3 to 4 meter

Available in full length so less joints and couplers. Thus they are economical

Flow

Initially 50 % more flow in comparison to other & retain flow till end

Initial flow gets reduced slowly because of rust

Initial flow is 40 % more

Initial flow reduced by 40 to 50 % after 5 to 10 years

Full and constant flow from initial stage which is 25 % more than GI Pipe

Effect of rust

Question of rust does not arise

Get rusted

Do not get rusted

Rapid rust formation

It is rust proof therefore long-lasting

Accumulation of particles forming rust

Very less change therefore dia of Pipe remains unaltered permanently

Particles accumulate heavily thus dia etc reduced on long run

Particles does not accumulate

Heavy accumulation of particles thus dia gets reduced after a period

Since diameter remains same it gives uniform flow permanently

Fitting arrangement

Very easy, quick and leakproof

Threading is required

Easy

Very laborious & time consuming

Economical in jointing. It is leakproof therefore no complaint for repairing. Prompt completion of scheme job.

Life

Lasts a lifetime

Gets rusted so required to be changed after 30 years

Less chances of changing

Required change after 20 years

Investment once in a lifetime

Cost of material

Very less expensive

Very expensive

Less expensive

Very Costly

Very economical compared to other pipes
