Product Description:

Underground GRP pipe/ FRP pipe

FRP winding pipe characteristics

1. Good physical mechanics performance

2. Being resistant to chemical erosion and longer service life

3. Excellent hydraulic characteristics

4. Lower installation and keeping cost

5. Flexible design and shorter reform term

6. No medium pollution

FRP pipe classification by application field

1.Chemical medium transportation pipe

2.Various producing process pipe (chemical process, paper making process, polluted water treatment process, sea water purifying process, food and drink producing process, and medicine producing process)

3.Pressure pipe for small hydroelectric power station on the ground and cycling pipe for power plant

4.Polluted water collecting and transporting pipe

5.Drink water transporting main line and tubing pipe

6.Oil field water injecting pipe and oil transporting pipe

7.Heat transporting pipe and sea water transporting pipe

8.Agricultural irrigation pipe

9.FRP set (ventilation, air-conditioner, chimney, cleaner) and piping

10.Gas drainage pipe for mine

FRP pipe classification by pressure in working state

1.Medium and low pressure pipe 0.6MPa2.5 MPa

2.High pressure pipe5.5MPa24 MPa

3.Mobile gravity pipe (which can be used when the pressure is under 0.6MPa)

4.Vacuum tube, external pressure pipe or siphon

If you have interest in the FRP pipe, please provide the following parameters: media, pressure and the use of the environment (overhead or buried), temperature, stiffness requirements, connections, we shall provide you most competitive price. Looking forward to our cooperation!

Q:What is the whole heat exchange fresh air ventilator?
Depends on the main control panel is not cold and warm, single cold common motherboard. Only a generic motherboard can be changed. In the single cold air-conditioning on the outdoor machine to install the appropriate specifications of the four-way valve, adjust the amount of refrigerant to the appropriate level can be.
Q:Public building design, the building structure and water is generally designed by the Architectural Design Institute, air conditioning and ventilation is based on the design of the interior? Or first air conditioning ventilation?
Aluminum alloy metal shell better than the plastic shell; we all know that most of the market is now charging the lithium battery, lithium battery is the only drawback is the possibility of a long time with the explosion, so the use of aluminum Alloy shell, much better than steel; polymer battery is good, but the price is expensive,
Q:Space blowing wind is not cold how is it?
The general level of more than 12 layers when you need to use.
Q:Air conditioning ventilation when the sound is a big reason
No matter, it is best to cut the distance between the material and the roof, like an arbor. Otherwise it is not foam board with it
Q:Air to water heater host and air conditioning host is not the same
This test with a small sample length 127mm, width 12.7mm, the maximum thickness of 3.2mm. In the absence of ventilation test chamber. The top of the specimen (6.4 mm place) is clamped with a clamp on the bracket and the longitudinal axis of the specimen is kept vertical. The lower end of the specimen is 9.5mm from the lamp tip and 305mm from the dry absorbent cotton surface. Bring the Bunsen burner and adjust it to produce a blue flame with a height of 19mm. Place the Bunsen Lights flame at the bottom of the sample for 10s, then remove the flame (at least 152mm away from the specimen) and write down the sample. Burning time. If the flame of the sample within 30s after removal of the flame is extinguished, the original lamp must be moved under the specimen again, re-ignite the sample for 10s, and then remove the Bunsen burner again and note the flame burning And flames burning the burning time. If the sample droplets drip, let it fall into the sample under the 305mm cotton, to see whether it ignited cotton. If the absorbent cotton is on fire, the rating should be taken into account. Specific grading indicators are as follows. Test Item 94V-094V-194V-21 Ten-time ignition Total flame burning time Maximum value (S) Individual flame burning time Maximum value (s) Flameless burning time (s) Yes Flame drop No No Allow only short time Burning general UL yellow card on the thickness of the test strip is divided into: 1/8 inch, 1/16 inch, 1/32 inch thickness, that is, 3.2mm, 1.6mm, 0.8mm three grades test.
Q:Ventilation is very good, why still have to install fresh air system
You are a single raft toilet wipes Pie Tanzhuang open card would like to confirm what? Contract notarization or. The The If it is contract notarized, generally notary value of 0.25% -0.3%
Q:Home 2 air conditioning is the cooling of electricity or heating electricity? How much power is spent in hours
After learning that feel boring, to diverted it, brush point repair it. Architectural design institute will need to design equipment (that is, plumbing) design talent, that is, will generally participate in architectural design, the wages should be
Q:External wall insulation method of operation There are several combinations of materials
30-150 per square meter has, mainly to see the material, thickness and so on
Q:Single cold air conditioning function can not change the cold and warm?
Air conditioning heating than the cooling power consumption, power consumption and ambient temperature and set the temperature has a great relationship, the general cooling 1 hour 1-2 degrees, heating if the auxiliary heating about 2-3 degrees. If you want to save the appropriate temperature can be set higher, the general and the ambient temperature difference of about 5 degrees people feel more comfortable, shut off undesirable, not reach the purpose of saving.
Q:The United States direct mail dyson hp01 Dyson air purification cooling machine triple in the country to warranty it
Among them, the extruded polystyrene gypsum composite board is based on paper gypsum substrate, the use of adhesive and extruded polystyrene board through the factory processing compound
