Abstract
The invention relates to a composite pipe for heat supply, which is prepared from the following materials in parts by weight: 85 parts of atactic polypropylene, 11 parts of nylon 66, 0.5 part of activating agent, 0.5 part of antioxidant and 0.5 part of coupling agent. The service life of the composite pipe is 50 years, the working temperature thereof is 95 DEG C and the working pressure thereof is 1.0MPa-1.6MPa.
Description
Technical field:
The present invention relates to the plastic tube used in the hot-water heating outside networks of heat supply field, be specifically related to a kind of heat supply composite pipe.
Background technique:
The plastic tube that with the polypropylene is main raw material is widely used on water supply and sewage work, at low temperature with on application is arranged also than the low pressure Heat Supply Engineering, but general temperature is no more than 95 ℃, pressure is no more than 0.6MPa, can only be applied in the indoor heating system of lower temperature low pressure, can't guarantee on outdoor two, three grades of heating networks, to use safely.At present, the plastic tube of carrying out HG20539-92 all can't guarantee to use safely under 1.0～1.6MPa, and embrittlement takes place when being lower than-20 ℃ in ambient temperature easily.At present, heat supply pipeline still uses Low Carbon Steel Pipe, influence working life on average about 10 years because of what it was subjected to water quality, environment, and the corrosion thing problem that results in blockage is more serious, gives energy-saving and emission-reduction, urban beautification environmental development, uplifts the people's living standard and take in and promote the household measurement heat-supplying charge and bring inconvenience.
Summary of the invention:
In order to solve the problem that exists in the background technique.The invention provides a kind of heat supply composite pipe, this composite pipe working life is in 50 years, operating temperature at 95 ℃, pressure at 1.0～1.6MPa.
The technical solution adopted in the present invention is: this heat supply composite pipe is made by following raw materials according, each raw material by weight ratio: 85 parts of random polypropylenes, 66,0.5 part of activator of 11 parts of nylon, 0.5 part of antioxidant and 0.5 part of coupling agent.
The invention has the beneficial effects as follows: the present invention mainly solves Low Carbon Steel Pipe working life shortly needs the frequent updating transformation bring higher maintenance management cost, destroy problem such as urban environment, avoids running, emits, leaks the energy waste, the corrosion thing that bring and stop up radiator or instrument and reduce heating efficiency, measure because of water quality inferiority can't advance branch family heat.The Low Carbon Steel Pipe that plastic tube of the present invention replaces extensive use now is the revolution that heating industry is energy-saving and cost-reducing, advance heat metering reform and development, reduction operation maintenance management cost.This invention has and building suitable service life in working life, can reduce the operation maintenance management cost greatly, effectively cuts the waste, and effectively improves heating efficiency, increases substantially the corporate social benefit, ensures for the hotlist safe handling provides the non-corroding thing to stop up.Working life of the present invention about 50 years, operating temperature about 95 ℃, pressure is at 1.0～1.6Mpa.
Embodiment:
The invention will be further described below in conjunction with embodiment:
Heat supply composite pipe of the present invention is according to existing production technology, made by following raw materials according: 85 kilograms of random polypropylenes are (available from the safe chemical industry of Guangzhou ancient cooking vessel Co., Ltd, softening point ℃: 140 ± 10, viscosity: mps/170 ℃, density: 0.89 ± 0.01, flash-point: 220-250) 11 kg nylon 66 (molecular weight is 15000～30000), 0.5 kilogram of activator B-480 (available from Anhui Jinma Rubber Additives Co., Ltd.), 0.5 kilogram of antioxidant 1010 (available from Switzerland Ba Jiaji company), 3 kilograms of coupling agent HC-NC (available from the little great prosperous plastic additive of peace Co., Ltd).
The heat supply composite pipe pipe thickness that is made by above-mentioned material is within 7～20mm, and its thermal conductivity is 1/200 of a steel pipe only, so thermal insulation property is preferably arranged.Placement, tubule is threaded through employing, and big caliber adopts hot melt to be connected with flange, and the bigger pipeline section of the longer heat expansion of pipeline is adopted the compensation of flange direct-burried sleeve expansion joint.After this invention is gone into operation, can effectively solve Low Carbon Steel Pipe corrodes the fast life-span and lacks, stops up, repeats to destroy problems such as environment, maintenance cost height, maintenance difficult, thermal loss are big, heating quality difference, the saving that meeting brings steel to country, the saving of energy, the reduction of caloric value.
