The glass-lined equipment of the utility model uses going up of full forged steel clamp to block and following card all is material with full forged steel 35 steel; And adopt the forging of program control pad die forging system technology to form; According to last card and the structural feature classification forging of card down, said full forged steel 35 steel that material adopted of going up card and following card meet the requirement of GB/T699-2006 during forging.In addition, the glass-lined equipment of the utility model is high with the manufacturing efficiency of full forged steel clamp, and cost has also obtained reduction.
Going up of the utility model blocks forging and blocks forging down through annealing in process; Eliminated internal stress; And the standard according to JB/T4726-2000 is tested; Forging all meets the qualified requirement of II level, so the glass-lined equipment of the utility model meets the requirement of iso-stress with full forged steel clamp, and make the handy material of clamp economize most and also tensile force maximum.
The nut material of the utility model is not less than 8 grades, as 8.8 grades; The performance rate of said packing ring can be 140HV.The following card bolt of the utility model can adopt M12, M16, M20, M24 and M28; Nut 12, nut 16, nut 20, nut 24 and nut 28 that nut employing and M12, M16, M20, M24 and M28 bolt matching use; The utility model has been unified the Dimensions of product, makes production mould minimum and the product adaptation market scope is maximum.
The glass-lined equipment of the utility model through repeatedly tension test, all meets the pertinent regulations of glass-lined equipment clamp in the HG/T2054-2007 standard with full forged steel clamp through check.
The glass-lined equipment of the utility model meets the standard of the existing new content regulation of country with full forged steel clamp; Said full forged steel clamp is used for glassed steel pressure vessel; The vessel flange fastening system is very safe, has avoided the production safety accident that causes because of the clamp material is defective.
