配液时应将水按比例放入酸洗槽中，然后再按比例缓慢加酸，防止倒酸速度过快引起飞溅伤人。 7.2 酸洗处理，首次操作应先在小试样局部面上或类似的材料上作试验。 7.3 酸洗过程中，操作人员必须认真仔细，及时观察，防止钢管表面腐蚀过重。 7.4 酸洗后钢管表面不得有明显的腐蚀痕迹，不得有颜色不均匀的斑纹，钢管表面不得有大量氧化皮。 7.5 酸洗钝化液都系腐蚀性溶液，而且酸洗溶液还具有毒性，故操作人员在操作时，必须严格遵守操作规程和穿好耐酸服，带好手套，口罩与防护眼罩等劳防用品。酸洗时，操作人员必须带上检查合格的防毒面具，并在专人监护下进行。 7.6 上述的酸洗配方及操作、浓度、体积比、液体温度和操作时间可根据情况允许做小量适当的调整。酸洗液可重复使用，但必须保证适当的浓度和体积比。 |

7.4 The surface of pipes after pickling should not leave trace of corrosion, so as spots of color differences and oxides coats. 7.5 The solutions of pickling and passivization are solution with corrosion, in addition, the pickling solution is also toxic. Therefore, the operator should obey the operation procedure and wearing the anti-corrosion coat, gloves, masks and glasses of protection. During the procedure, the operator should wearing the proper respirator, and working under surveillance. 7.6 The formula of the pickling solution, operation, concentration, volume ratio, solution temperature and procedure duration could be adjusted in small range. The pickling solution can be reused, but the proper concentration and volume ratio should be maintained. |

Put water into pickling bath proportionally when preparing solution and then add acid proportionally and slowly so that make sure the water won’t splash. 7.2 Acid pickling. For the first time, before getting start, do experiment on the local surface of a small sample or similar material. 7.3 The operators must be careful、observe in time and avoid the surface of the steel tube corroding too much in the process of acid pickling. 7.4 After acid pickling, the surface of steel tube can’t have marks of corrosion apparently and can’t have streaks of color variegation and too much oxide skin. 7.5 The solution of pickling passivation is corrosive solution and pickling liquor has deleteriousness. So the operators must obey the rules and get acid suit and wear gloves、masks and eye shields and so on in the process of operation. The operators also must wear antigas mask of passed examination in the process of acid-washing and under the observing of certain person. 7.6 The acid-washing formula and operate、concentration、volume ratio、temperature of liquor and time of operation mentioned above can make small appropriate adjust. Pickle liquor can be used reduplicate, but must be sure appropriate concentration and volume ratio. 以上仅为个人翻译，请各位评价  |

During the preparation of acids melange, the water should be filled into the pickling tank first, then the acid should be added slowly, to prevent the splash of the acid solution. 7.2 pickling treatment, every first manipulation of pickling treatment should proceed after a test of small sample on small surface of the material or other similar material 7.3 During the procedure of pickling, the operator should always be careful in observing the situation of the surface, in case of the surface of iron pipe been over corroded. |
