Parker焊接接頭系列

Introduction
In the chemical industry, process pressures are climbing higher
and higher. The utility field, with its high steam pressures and
hydraulic and pneumatic shutdown systems, demands the
utmost in reliability. Nuclear power plants with their “hot” materials
also have massive reliability problems. Such problem
areas have given rise to the increased use of the permanentweld-
type tube fittings which provide a sturdy, tight integral
line system that remains unaffected by shock, vibration or
thermal distortion. The Parker Weld-lok® line of permanent
socket weld tube fittings meets the most exacting requirements
of any system.
Heat Code Traceability
Parker Hannifin’s Instrumentation Connectors Division offers
Heat Code Traceability (HCT) on CPITM, A-LOK®, Instrumentation
Pipe, Automatic Buttweld, and Weld-lok®.
HCT refers to the fact that a specific part can be traced back
to the original mill heat of metal from which it was made.
Beginning with the original melt, a package of documents is
created which completely describes the metal in physical
and chemical terms. The end result is that a number, which
is permanently stamped to the part, refers back to the document
package.
The HCT number is stamped on the material (bar stock or
forging) prior to manufacturing. The concept is useful
because it provides a method for complete material
accountability for the manufacturer and end customer.
