I. Introduction
PVC-U
building insulation casing is PVC-U resin as the main raw material,
adding various stabilizers, anti-aging agent, impact agents and other
additives made by extrusion and molding of various models of hard PVC pipe.
Second, the application field
1, power
2, telecommunications line jacket
3, embedded wall construction, underground cables, etc.
Third, the product characteristics
1, compression: electrical casing wall thickness 1.6mm I
produced in more than able to withstand more than 750N pressure, it can
also be surface mounted laid in concrete without pressure and sabotage;
2, impact, heat: electrical conduit in concrete pouring
process, subject to normal tamping impact will not break, and by the
heat of condensation in the construction process, the same soft;
3,
moisture acid: PVC electrical conduit acid proof performance, will not
rust, all the required connections with PVC adhesive bonding,
infiltrated the inner tube waterproof, moisture better, so in corrosive environments conducive to the use;
4, fire retardant: PVC electrical conduit from the fire
self-extinguishing (leave the flame that will self-extinguish within 30
seconds), the flame will not spread along the pipeline;
5.
Insulation: PVC electrical conduit has excellent insulation properties,
in the flooded state AC2000 volt, 50HZ not breakdown. To prevent accidental electrocution, the international
community tends to be better insulated than the ground, Lu Yu-brand PVC
electrical conduit is to meet this requirement;
6, pest control mice: PVC electrical conduit due to special
additives have been added, does not emit odors and attract vermin biting
damage;
7,
the construction is convenient: 32mm or less portable electrical
conduit can be cut off with a tubing cutter, insert the appropriate
special spring in conduit, at room temperature, can be bent into the
desired artificial angle with PVC adhesive can quickly and easily Conduit pipe connected into a desired shape.
Fourth, product specifications
Executive Standard: JG3050-1998 Unit: mm
Telecom casing pipe specification Unit: mm
Fifth, construction methods
PVC-U insulated flame retardant electrical conduit, pipe
fittings using PVC adhesive glue connected, specific instructions are as
follows:
1. Cut the pipe: Use scissors or owned hacksaw cut the PVC
conduit to use the desired length, the cut should be smooth, used
scissors back chamfering.
2, pipe and pipe fittings Connection: keep the adhesive surface clean before connection. In the outer surface of the pipe insertion end and fittings
inside the socket surface evenly coated with adhesive, after about one
minute to force the tube inserted into the inner pipe is fixed, 10
minutes stereotypes.
3, pipe bending: bending spring with the corresponding
specifications provided by the factory, insert the tube, can be bent,
the following points should be noted that when the elbow:
(1) shall be provided with the appropriate size of the factory
springs, and can not be confused with standard models, otherwise it
will cause damage to the springs and pipes;
(2) the time required to bend slowly, otherwise easily damaged pipe and spring;
(3) is not removed before the spring, so do not force retraction elbow, to prevent damage to the spring;
(4) When the spring is not easy to remove, pull the side edge
counter-clockwise rotation of the spring, spring diameter contraction,
can be removed;
(5) construction below 0 ℃ weather, usable cloth tube bends require repeated friction to heat up and then bend it properly.
Shipments
of goods priced according to the size of the power meeting, planned
product Shandong Foreign customers vehicles (commonly used models)
company with inventory, are in stock, money to be arranged within two to
three days delivery, Shandong province this invention to customer
vehicles, After
the factory by 50 km / h control the arrival time; order products (very
used models) the company does not have inventory, large production
according to customer request, is required to pay 20% deposit, delivery
time and circumstances of the production line scheduling, Please call customer service to understand the situation beforehand.
Transportation:
Round trip vehicle shipped in large quantities by small quantities go
picking station, the specific equipment and freight shipments that
require immediate communication and logistics confirmation.
