Pressure-balanced metal corrugated compensator special features in those aspects

First, chemical analysis of the chemical composition of the pressure-balanced metal corrugated compensator to see if the chemical composition meets the standard requirements. Secondly, it is also possible to test the pressure resistant pipe by pressure test The specified pressure value cannot be maintained for not less than 5 seconds and no leakage is observed. The traditional supply hydraulic pressure test is 2.45 MPa. air pressure test is P = 0.5 MPAa. also requires a corrosion test, the supply of corrosion-resistant steel pipe in accordance with the mutually agreed standard provisions or corrosion methods for inspection, stainless steel pipe does not tend to intergranular corrosion.
Second, the pressure-balanced metal corrugated compensator wall thickness is generally lower, so the lower range of variance is better than the lower range of variance, and the pressure loading capacity is higher. Welding quality is mainly seen by eye or defect detection. Based on the superior anti-corrosion properties of welded straight seam stainless steel pipe, it can also be used to transport chemicals such as gases and oils. Pressure-balanced metal corrugated compensator production process is simple, high production efficiency, low cost, and rapid development.
 
Third, the strength of pressure-balanced metal corrugated compensator is generally higher than that of pressure-balanced metal corrugated compensator. Can produce large diameter, pressure-balanced metal corrugated compensator, can also produce different pipe diameter, the same width pressure-balanced metal corrugated compensator. The thickness of pressure-balanced metal corrugated compensator is 2.5~3.7mm. the thickness of 3PE anti-corrosion pressure-balanced metal corrugated compensator of the same specification is generally +0.5.
Fourth, the coating has good temperature resistance and can be used in the environment of -40℃~300℃. Used for a long time. Will not burn and soften; high strength, test pressure at room temperature up to 5.5Mpa; low fluid resistance, the pipeline does not scale, improve the efficiency of transport; acid, alkali and salt corrosion, the pipeline will not rust in 50 years. Pressure-balanced metal corrugated compensator causes accelerated oxidation on both inside and outside sides of the weld and near the weld area.
 
Fifth, because there are discolored areas where oxidation can be seen, the color is related to the thickness of the oxide layer. For the interior of the stainless steel HF welded pipe, oxidation and discoloration can be reduced to small by using an appropriate back-blowing method. After the pressure-balanced metal corrugated compensator is welded and formed, it is often necessary to perform post-weld treatments like pickling and grinding to remove the oxidation layer (tinting) and regain the corrosion resistance.
