Polyvinyl chloride (PVC) is the biggest characteristic of flame retardant, so is widely used in fire protection applications.But the polyvinyl chloride (PVC) in the process of combustion will release hydrogen chloride and other toxic gases, such as dioxin.

Polyvinyl chloride (PVC) combustion can be divided into two steps.In 240 ºC to 340 ºC before burning decomposition of hydrogen chloride gas and alkadiene contain a double bond, and then in 400-470 ºC carbon burning.


~~~~~Several kinds of common PVC pipes:~~~~~
1. PVC Water Pipe:
Overview:
PVC water pipe is health grade PVC resin as the main raw material, adding quantitative stabilizer, lubricant, filler, toner, etc., the plastic extruder extrusion molding and injection molding machine, through cooling and solidifying, finalize the design, testing, packaging process to produce a kind of water supply pipe.

Specifications:
PVC pipe size has Φ20,Φ25,Φ32,Φ40,Φ50,Φ63,Φ75,Φ90,Φ110,Φ125,Φ140,Φ160,Φ180,Φ200,Φ225,Φ250,Φ280,Φ315,Φ355,Φ400,Φ450,Φ500,Φ630,Φ720,Φ800 etc.

For PVC hoses - as the nominal pressure, pressure of said expressed in Mpa.Nominal pressure regulation is 0.63 Mpa, 0.8 Mpa, 1.0 Mpa, 1.25 Mpa, 1.6 Mpa, etc.

Minimum diameter of the pipe for each pressure area: 0.63 Mpa pipes, the minimum diameter is 63 mm, manage the minimum diameter of 50 mm 0.8 Mpa, 1.0 Mpa pipes, the minimum diameter of 40 mm, 1.25 Mpa pipes, the minimum diameter is 32 mm, 1.6 Mpa pipes, the minimum diameter of 20 mm and 25 mm.Pipe length is 4 m, 6 m, 8 m.
