With the development of national economy and people s living standards improve, the thin-walled push elbow has become the new trend of
development of the domestic water supply pipeline system. Domestic thin-walled push to elbow the late 1990s before the advent of new pipe,
due to health and safety, high strength, good corrosion resistance, durable, long life, maintenance-free, and other aesthetic features,
pushing the system bend the strong momentum of development, have been widely used in building water supply and drinking water pipeline.
learned from parties concerned : Stainless steel compression fittings and push elbow connected with thin-walled stainless steel tube will
generate a new national standard, the connection of these two products, and construction specifications will also have national standards in
stainless steel production, only ferrochrome a accounted for about 40 percent of the cost of production. Push the system bend mainly in:
Varieties products of different specifications of the world push the system elbow, a total of about 150 000, China has so far produced only
2 million, and most of the generic products. Push the system elbow, according to even the different varieties and specifications in actual
use, in accordance with the use and performance, the use of specific use to produce good performance and trends, the most cost-effective.
Two, dimensional tolerances and rotation accuracy, pushing the system in China bend head close to the level of foreign brand names, there is
still a wide gap between the dispersion in the size of the deviation. In addition, countries have already begun to research and application
of "non-repeatable runout such a fine rotation accuracy indicators, and our research in this area is still vacant.
Third, in terms of vibration, noise and different sound, Japan has launched a quiet and ultra-quiet bearings, our stamping elbow vibration
(acceleration), extreme value level be compared with Japanese products, the general difference of more than 10dB. Baosteel to carry out the
R & D of the shaft furnace production of ferrochrome water craft, cheap ferrochrome ore powder can be directly used its own processing to
produce content for stainless steel smelting ferrochrome water, not only can effectively reduce the cost of stainless steel production,
substantially reducing power consumption, can digest iron dust in the production process to reduce solid waste emissions.
In the special conditions stamping elbow application technologies of stamping elbow there is a big gap of proportionality. Precisely because
of our push elbow there is inadequate from a variety of specifications to the function and quality, therefore, not only in exports, the vast
majority of departments for the low-end products, the elbow uniform price of each set of push system is only about $ 0.4, does not have any
technological competitiveness, but also in some important domestic host or domain, is basically the entrance bearing the "domination". These
industries or areas, and there is a pillar industry or field.
Domestic push elbow raw material market in the processing of ferrochrome, commonly used mineral hot furnace, need to consume a large amount
of coke and electricity, coupled with the limited resources of domestic chrome ore, ferrochrome prices remain high, directly increases the
production of stainless steel costs. Stainless steel production, only the ferrochrome alloy one, accounting for about 40 percent of
production costs. At present, the domestic iron and steel raw materials markets in the processing of ferrochrome, commonly used mineral hot
furnace, need to consume a large amount of coke and electricity, coupled with the limited resources of domestic chrome ore, ferrochrome
prices remain high, directly increases the cost of production of stainless steel. Push the system bend in the actual production of certain
raw materials and process for production, to ensure the contribution and value in actual use.
