Remove or hide the "View" tab on a node
You should be able to do this using css, or try using the code below or the tab tamer module   

function MYMODULE_menu_alter(&amp;$items) { 
  $items['node/%node/view']['access callback'] = 'MYMODULE_disable_node_view';
  $items['node/%node/view']['access arguments'] = array(1); 
} 

function MYMODULE_disable_node_view($node){
        return false;
}
