Degree,.
In addition, 3 surface of the stratum granulosum is coated with composite metallic painting, the composite layer is composite stainless steel layer, is increased
The wear-resistant effect of granulosa, fastening is more firm when assembling, while also utilizing lamination layer structure, when screw rod being made to assemble, with screw thread
The leakproofness of layer is stronger, prevents chemical liquid from entering the gap between screw rod and screw thread layer, and considerably increase bolt uses the longevity
Life.
In addition, being sprayed with the wear-resistant protective paint of antirust on the nut 2, reduce erosion of the chemical liquid to nut.
A kind of the utility model chemical equipment high-strength composite bolt, is mainly used for chemical equipment, prevent for a long time with
To generate corrosion, stability is strong, compact-sized, and assembling is secured, considerably increases service life for chemical liquid contact.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is equally included in the patent within the scope of the utility model.
