Abstract: Introduced here in the article are the manufacture processes and equipment of some foreign specialized producers engaged in making stainless steel and hi-Ni alloy steel long pipes and a comparison of the domestic production in this field with such companies as well. Although the development of the stainless tubular products is regarded as rather faster than that of other kinds of steel products in the country,the grades of such pipes are not high enough. Therefore developing higher grade stainless steel tubular products,including long pipes in stainless steel and hi-Ni alloy steel is just a demand for development of domestic industry and highly-sophisticated technologies as well.
