Product Description:
High strength,lower weight,quick installing
Strong resistance to erosion
Good hydrodynamic performance,save piping pump energy.
Excellent insulation. Designable easily
Lower maintenance fee,saving engineering fee over 70%.
Long working life, high responsibility, good engineering profit,Larger diameter, lower cost
Non-toxic, can transport drinking water
Connection way of pipes:
| 1.Double seal socket connectionIt is suitable for FRP pipe with sand when ground pipe with
high pressure. It can do one connector pressure testing. |
| 2.Socket adheringit is suitable for CPVC,PVC,PP/FRP high pressure and
complex loading big diameter piping. |
| 3.Connecting face to faceIt is suitable for High, middle, low pressure piping and
fitting connection. L and T deal with application situation. |
| 4.Socket“O”seal connecting Nylon pole key lockIt is suitable for the piping with lager vertical elongating stress, such as deep well pipe. |
| 5.Flange connectionJB、GB、ASTM、DIN、NF、JIS
It is suitable for middle and low pressure piping and 1200 equipment. It uses HG, JB, GB, ASTM, DIN, NF, JIS standard. |
| 6.Glove connectionIt is suitable for middle and low piping and short piping.
It can be applied in connecting with metal or other materials. |
Application:
Chemical industry,paper industry,waster water treatment,desalinator.pharmaceutical industry,HVAC,chimney.
Pipes transportation,storage and installation:
1.Pipes can not connect each other from side to side. It must be separated by the cushion wood. The storage layer highness should be lower than 2 meter.The pipe can be gloved for different diameter, but need prevent any damage the pipe wall.
2.Avoid any strong impact when transportation and loading.
3.Pipes need storage on flat ground. The storage highness should be lower than 2 meter. Storage place need far away the fire.Avoid long period storage outside.
Installation：
There are three kind of piping installation: over head, on the ground, under the ground.
1.over head installation
1.1Because of lower elastic to Composite and FRP pipes,it need suitable design for supporting and span.For decreasing connector stress,supporters need near connectors.The lock can not be very tight,to keep enough space for temperature expanding.
1.2Pipe supporters have hooks, supporters, foots. They need keep connection with pipe wall over 180.On the supporters the rubber cushion need be over 3-5mm thickness and fasten by bolts.
1.3The connecting between Pipe and pipe,pipe and fittings,need be according to the process.
1.4Any warp when installation,on the horizontal should be ≤2-3/1000,on the vertical≤2-5/1000, on the slope 3/1000 of span of two supporters.
1.5Layout of piping and type should be meet requirement on loading,tolerance and settlement.The span is designed according to liquid density of 1.3,and-10~75℃temperature.For detail,please refer to data sheet.
1.6When bolts connect flange,be attention on distort and support pole to avoid over distort to damage the flange.
2.installation for under ground pipes
There are special consideration for under ground pipes.Except above items,the slot need to be made of tile with short supporters.The depth of slot is >400 mm for pavement,and>700mm for truck road.It can be calculated according to Jansen formular.Normally,it is 2 times of diameter,but not less than 500 mm.when burying,need avoid any stone in the soil,then compaction.If necessary,the concrete cover can be used.
