upvc 90 degree elbow pipe fittings
1. Concept
UPVC known as hard PVC, which is an amorphous thermoplastic resin, an additive must be added by the
polymerization of vinyl chloride monomer is made (such as stabilizers, lubricants, fillers, etc.).
In addition to using additives, but also adopted blended with other resins modified approach, it has
obvious practical value. These resins are CPVC, PE, ABS, EVA, MBS and the like. UPVC high melt viscosity,
poor mobility, even if the increase injection pressure and melt temperature, liquidity will not change
muchFurther, the resin molding temperature is close to the thermal decomposition temperature, the molding
can be very narrow temperature range, is a hard molded material.
2. Product Features
A: strong corrosion resistance: general cast iron pipe, galvanized pipe compared, PVC pipe is highly
resistant to corrosion, resist acid, alkali, will not rust scale. When using do not worry, "the red
water" phenomenon.
B: fluid resistance: PVC pipe wall is very smooth. Its surface roughness coefficient of only 0.009,
fluid resistance is small, does not unduly reduce the water pressure.
C: high mechanical strength: Water supply UPVC pipe has good pressure resistance, impact resistance,
tensile strength at room temperature for one hour may be subject to 110 atmospheres without rupture.
D: non-toxic health: Water supply UPVC pipe using a unique green instead of the traditional
lead-free formulations lead salt compound formulation system, and thus will not damage water quality
and affect human health.
E: light texture, easy installation and construction: the density of PVC pipe for the fifth general
cast iron, conveying easy loading and unloading. And use Paste Special to paste or elastomeric seals
agent sockets, installation is simple and quick. optimum temperature performance
F: water supply: The water supply UPVC pipe temperature range, with room for the best. Temperature
is low, fragility, unfavorable installation and construction; low temperature, the tensile strength
decreased,reducing the pressure resistance performance.
G: watertight good: 15 minutes after the adhesive bonding, adhesive strength can reach 12.5 / C or
more,after years of use there will not be significantly decreased, while the resilient seal ring at
the socket, there is also the PVC pipe quite useful life, no leakage of aging into account.
3. Distinguishing Features of UPVC and PVC
(1). Advantage of UPVC pipe fittings, pipe
Light: the proportion of UPVC material is only one fifth of cast iron, transport, easy to install,
and reduce costs.
Excellent chemical resistance: UPVC has excellent resistance to acid-base properties, in addition
to close to saturation point of strong acid or strong Oxidising agents atmaximun outside.
Non-conductive: UPVC material can not conductive, but also from the electrolysis current corrosion,
should this without secondary processing.
Not burn, nor combustion, no fire concerns.
Easy to install, low cost: cutting and connection is very simple to use PVC glue connection proved
reliable and safe, easy operation and low cost.
Durable: excellent weatherability, and can not be corrupted by bacteria and fungi.
Resistance, flow rate: smooth wall, a small loss of fluid flow, the dirt is not easy to be attached
to the wall in a smooth, relatively easy maintenance and low maintenance costs.
(2).Advantage of PVC pipe fittings, pipe
PVC is polyvinyl chloride, is 43% of oil and 57 percent of the salt out of a synthetic plastic products.
Compared with other types of plastic products, PVC and more effective application of the raw materials,
reducing fuel consumption. Meanwhile, PVC manufacturing energy consumption is very low. And the use of
PVC in the latter products, can be recovered and converted into other new products or burned to obtain
energy. Will be added in the production of PVC stabilizer, but there are non-toxic and toxic stabilizers
of the points, and only joined the class of toxic lead salt stabilizer, will produce problems.
4. UPVC excellent performance
With UPVC additives and formulation technology development and improvement, its use is not only to
fittings and pipes in the structure and properties of PVC drainage molecules, coupled with the
diversity of additives, as well as maturing formulation technology, makes UPVC have other polymer
materials can not be compared with the excellent performance, mainly in the following areas:
(1). The stability of a processing
UPVC added during the production of the modified tin stabilizer, not only environmentally friendly,
but also enhances the thermal stability and dimensional stability.
(2). Weatherability
Refers to the ability of various weather-resistant plastic. Including visible light and chemical agents encountered in ultraviolet light,
moisture, temperature and atmospheric chlorination during product use. The most important weather
resistance, including not fade resistance, resistance and physical properties of powder persistence.
After weathering performance UPVC modified and ASA have been comparable, but also has better physical
and chemical properties. As we all know, in all polymer materials which, ASA for its excellent
weather resistance known to the world, UPVC the weather side has completely replace ASA.
(3). Retardant properties
UPVC itself has a good flame retardant properties, general UPVC oxygen index are 27 or more, through
UPVC special modified oxygen index can reach even more than 42 or more, which is unmatched by other
common plastics.
(4). Performance of diversity
Add in UPVC different performance additives, UPVC will exhibit different properties. This makes
UPVC showing diversity. Making it more versatile. Making it one of the world's largest production
of plastic products.
