热镀锌方矩管在我们的建筑行业中得到了大量的应用，那么今天方管生产厂家就带大家一起来学习下怎样从表面商判断热镀锌方矩管的质量好坏。

Hot dip galvanized rectangular tubes have been widely used in our construction industry. Today, the square tube manufacturers will take you to learn how to judge the quality of hot dip galvanized rectangular tubes from the surface quotient.

为了进步方管的性能，能够对方管进行热浸镀锌。热浸镀锌是一种热处理技能。在方管热浸镀锌过程中，为了满足要求，需求进行接连的查验。假如不丈量管子的质量，会有许多影响。

In order to improve the performance of square tubes, the square tubes can be hot-dip galvanized. Hot dip galvanizing is a heat treatment skill. In the process of hot-dip galvanizing of square tubes, continuous inspection is required to meet the requirements. If the quality of the pipe is not measured, there will be many effects.

查验的一个要求是附着能力，即镀锌热镀锌方管的厚度。由于热镀锌方管的镀锌层是决议其是否到达防腐要求的当地，因此在查验过程中能够运用专业的丈量工具。在查验过程中，热镀锌方管的镀锌层厚度有必定的规定，运用时需求根据这些规定进行标识。

One of the requirements for inspection is the adhesion capacity, that is, the thickness of galvanized hot-dip galvanized square pipe. Since the galvanized layer of hot-dip galvanized square pipe is the place to determine whether it meets the anti-corrosion requirements, professional measuring tools can be used in the inspection process. In the inspection process, there are certain regulations on the thickness of the galvanized layer of the hot-dip galvanized square pipe, and it is required to identify according to these regulations during application.

其次，查看的根据是均匀性，即镀锌层的厚度。为了进步热镀锌方管在查验过程中的使用质量，制作后的厚度要求能到达使用规范，使其在使用过程中不呈现损害。

Secondly, the view is based on the uniformity, that is, the thickness of the zinc coating. In order to improve the service quality of hot-dip galvanized square tubes in the inspection process, the thickness after fabrication is required to meet the service specification, so that they do not show damage in the service process.

在查看过程中，要查看济南方管的牢固性，即方管之间的触摸精度。假如在运用过程中，热镀锌方管的精度太差，那么在运用过程中镀锌层就会脱落，导致在运用过程中被其他物体腐蚀，导致热镀锌方管不能正常运用。在查验过程中，能够选用简略的方法进行查验，即用两根热镀锌方管相互敲击。假如它们有杰出的特性，就不会呈现损坏，质量肯定有问题。

During checking, check the firmness of Jinan square tubes, that is, the touch accuracy between square tubes. If the accuracy of the hot-dip galvanized square tube is too poor in the process of application, the galvanized layer will fall off during the process of application, resulting in corrosion by other objects during the process of application, resulting in the normal operation of the hot-dip galvanized square tube. In the inspection process, a simple method can be selected for inspection, that is, two hot-dip galvanized square tubes are used to knock each other. If they have outstanding characteristics, they will not be damaged. There must be a problem with their quality.
