We promote into the market high-quality products that must
oust out all the law-quality falsifications. Strict approach towards the quality
makes it possible for us to manufacture products that correspond to the
international standards.
To test the raw material and ready-made product, sama Company possesses an
up-to-date quality control laboratory .In accordance with the sama Company
policy regarding the quality, the technical possibilities of the laboratory are
constantly widened.
The laboratory carries out quality control over the connection between the pipe
and the fitting at continuous cyclic changes of the temperature and pressure.
All the pipe batches undergo testing. The positive results of product testing
are the guarantee of perfect and problemless exploitation of pipes and fittings
during 50 years.
The durability of pipes for 90% depends on raw
material formula.
The incoming raw material and its main
characteristics are controlled by the laboratory.Time-proof reliability of
polymer pipes and the period of their exploitation are for 90% determined by the
polymer raw material quality.
The laboratory possesses the following
test-methods:
· Index of melt fluidity – this characteristic determines the polymer molecular
weight and the product quality to resist deformation during continuous
weighting.
· Melting temperature curve – this characteristic determines the technological
mode of reprocessing, and its analysis reveals how well-orders the polymer
structure is.
· Level of linkage – this characteristic determines the level of the modified
polymer and allows forecasting the long trickle life of conjunctions with metal
fittings.
· with satisfactory level of linkage are applicable for usage in pipe
production.
· Abruption resistance – this characteristic determines the resistance features
of the material and the pipe capability to resist high pressures.
· Elastic-plastic deformation characteristics – this complex of characteristics
that models the material condition at continuous usage of pipes in the condition
of changing pressure and temperature. |
