After being placed in a certain area for an extended period of time, brass tubes may develop surface rust and corrosion. This is an unavoidable aspect of their use. How should users clean these surface deposits?
1: Cracking
Cracking in brass tubes is relatively rare but does occur. Brass tubes inherently possess corrosion resistance and some crack resistance. In many cases, cracking occurs due to excessive force applied at a contact point, leading to uneven stress distribution. Under certain conditions, the areas subjected to greater stress may undergo physical changes, resulting in cracking over time.
2. Rusting
Rusting of metal pipes is unavoidable, though the extent varies. Among various metal pipes, brass pipes are relatively resistant to rusting. When storing brass tubes, users must avoid exposure to acidic gases or liquids. Although brass tubes have corrosion resistance, the specific chemical impurities within them and their potential reactions with acidic substances are unknown. Therefore, they should be kept away from acidic substances during storage.
3: Dust and oil stains
Dust and oil stains can be gently wiped off the surface with a cloth or sponge. During cleaning, avoid removing the oxide layer on the surface of the brass tube, as this layer serves as an auxiliary protective layer.
The above three issues are common problems that may arise on the surface of brass tubes.
Pricing of brass tube fittings by manufacturers
1: Place of origin
Brass tube fittings vary slightly by region. In more industrially developed cities, prices are generally lower. Typically, prices are set per kilogram. In major industrial cities, there are numerous manufacturers of brass tube fittings, with significant sales volumes. Many brass tube and stainless steel manufacturers offer lower prices, focusing on volume sales. Current prices range from 30 to 190.
2: Market price
The prices of brass tubing fittings are influenced by raw material market prices, which is an inevitable trend. The primary raw material for brass tubing fittings is copper, with the majority being metallic materials. The prices of metallic materials are subject to significant market fluctuations, leading to fluctuations in prices.
3: Material Quality
Although brass tube fittings appear similar on the surface, those with expertise can quickly discern differences in quality. These differences primarily stem from the quality of raw materials, which directly impacts the price of brass tube fittings.
The prices of brass tube fittings vary significantly across different sales channels. Users should select products based on their specific needs.
