| titleOfInvention | SAW process for straight welded steel pipe groove abluent and using method thereof |
| abstract | The invention discloses a kind of SAW process for straight welded steel pipe groove abluent and using method thereof, SAW process for straight welded steel pipe groove abluent composition is as follows: hydrochloric acid 10～20%, citric acid 10～15%, ammonium chloride 2～5%, hydroxyacetic acid 3～5%, sodium silicate 5～8%, nonionic surfactant 4.5～12%, corrosion inhibiter 1～2%, deionized water surplus.The present invention can be used for the groove face before SAW process for straight welded steel pipe and process, and effectively removes the oxide skin at steel-pipe welding groove and greasy dirt, thus reduces weld defect, improves weldquality. |
