熱鍍鋅方矩管在我們的建筑行業中得到了大量的應用，那么今天方管生產廠家就帶大家一起來學習下怎樣從表面商判斷熱鍍鋅方矩管的質量好壞。

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.

為了進步方管的性能，能夠對方管進行熱浸鍍鋅。熱浸鍍鋅是一種熱處理技能。在方管熱浸鍍鋅過程中，為了滿足要求，需求進行接連的查驗。假如不丈量管子的質量，會有許多影響。

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.

查驗的一個要求是附著能力，即鍍鋅熱鍍鋅方管的厚度。由于熱鍍鋅方管的鍍鋅層是決議其是否到達防腐要求的當地，因此在查驗過程中能夠運用專業的丈量工具。在查驗過程中，熱鍍鋅方管的鍍鋅層厚度有必定的規定，運用時需求根據這些規定進行標識。

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，查看的根據是均勻性，即鍍鋅層的厚度。為了進步熱鍍鋅方管在查驗過程中的使用質量，制作后的厚度要求能到達使用規范，使其在使用過程中不呈現損害。

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.

在查看過程中，要查看濟南方管的牢固性，即方管之間的觸摸精度。假如在運用過程中，熱鍍鋅方管的精度太差，那么在運用過程中鍍鋅層就會脫落，導致在運用過程中被其他物體腐蝕，導致熱鍍鋅方管不能正常運用。在查驗過程中，能夠選用簡略的方法進行查驗，即用兩根熱鍍鋅方管相互敲擊。假如它們有杰出的特性，就不會呈現損壞，質量肯定有問題。

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.
