Working principle: stainless steel stub ends is widely used in different industries, which can show good use value and performance in the industry. According to the nature of deformation, stub ends can be divided into elongation stub ends and compression stub ends.
Stainless steel stub ends is widely used in different industries, which can show good use value and performance in the industry. According to the nature of deformation, stub ends can be divided into elongation stub ends and compression stub ends. The common feature of the elongation stub ends is that the deformation area of the blank produces the tangential elongation deformation under the action of the tangential tensile stress. The deformation feature belongs to the elongation type deformation, and the limit deformation degree is mainly limited by the cracking of the deformation area. The common feature of compression stub ends is that except for the bending deformation of the metal near the fillet radius of the root of the vertical edge, the other parts of the deformation area of the blank generate the tangential compression deformation under the action of the tangential compression stress. The deformation feature belongs to compression deformation, and the stress state and deformation feature are the same as that of drawing. The limit deformation degree is mainly limited by the instability and wrinkling of the deformation area of the blank System. In addition, according to whether the wall thickness of the vertical edge has forced thinning, it can be divided into thinning stub ends and constant thinning stub ends. According to the blank and work piece edge shape of stub ends, it can be divided into inner hole (round hole or non round hole) stub ends, plane outer edge stub ends and curved surface stub ends, etc.

The conventional expression of the wall thickness of stainless steel stub ends includes sch10s, sch20s and other different pressure grades, which represent different thickness. It can refer to the pressure grade wall thickness table.
Stainless steel stub ends joint is one of the steel butt welded pipe fittings.It is usually a section inside the loose flange.
Loose flange is often used when the medium temperature and pressure are not high and the medium corrosion performance is strong. When the corrosion performance of the medium is relatively strong, the part of the medium contacted by the flange is made of high-grade corrosion-resistant material, such as stainless steel, and the external part is clamped by low-grade material, such as carbon steel flange ring, so as to achieve the sealing performance.The standard of steel flanging joint is GB12459 GB/T 13401.
Stainless steel flanging applications: LPG pipeline engineering, natural gas pipeline engineering, chemical plant, power plant, shipyard, pharmaceutical, dairy, beer, beverage, water conservancy, etc.
