Purchase of 304 stainless steel head 304 stainless steel flat head manufacturers, Hebei Cang Sheng Pipe most professional, stainless steel head, the lowest price stainless steel head material: 304,304L, 321,316,316L, 310S, 00Cr18Ni5Mo3Si2 (UNS S31500) (3RE60), 630, 00Cr22Ni5Mo3N (UNS S31803 / S32205) (SAF2205), 00Cr25Ni7Mo4N (UNS S32750) (SAF2507) 304,1Cr13,2Cr13,3Cr13,1Cr17Ni2, duplex steel, antibacterial steel and other materials. Common standards: JB / T4746-2002 GB / T12459-2005 GB / T13401-2005 quality DN200 * 3 butterfly stainless steel head, stainless steel head professional manufacturer DN550 * 4 stainless steel head, please call Cang Sheng Hebei Pipe Manufacturing Co., Ltd. dished head, also known as spherical head with a hem. By a spherical surface, a certain height of the straight edge and the radius of curvature of the cylindrical connecting the above two portions is substantially smaller than the radius of the spherical part of the composition of the transition. Dished head for a continuous curved surface, at the junction of three parts, the radius of curvature of the warp mutation, due to changes in the curvature, and thus there is a bending stress. Bending stress and tensile stress superposition results 316 stainless steel flat head standards, so this part of the stress is prominent in other parts. Compared with the oval-shaped head, his uniform stress distribution is better, but easier than working, so not ideal use in engineering. But when the elliptical head mold processing difficulties, then replaced with a dished head. 316 butterfly stainless steel head offer, priced to sell (certified), Baicheng stainless steel head by Hebei Cang Sheng Pipe Manufacturing Limited.
