In Drupal function hook_menu_alter() allows you to alter various properties of menu items. In your custom module, simply add the function. MODULENAME_callback_function will check the node type and hide the node view and edit from a particular node type. Here for our nodetype the hook_menu_alter() will call the callback function MODULENAME_callback_function, which will not show the view and edit tabs for our nodetype in Drupal.
