Black annealed steel pipe

黑色退火钢管又称黑色退火管，是一种经过高温退火处理的钢管。这种钢管在生产时不经过任何表面处理，因此表面颜色是在高温下暴露在空气中而变黑的，表面并没有变亮，呈现出黑色的外观。它的生产工艺简单，通常用于对表面光洁度和精度要求不高的场合。黑色退火钢管采用优质碳素结构钢为原料，经过精密加工而成。产品具有内外壁光滑、尺寸精度高、组织均匀等特点，保证了良好的流体输送能力和稳定性。此外，退火钢管具有优良的韧性和延展性，能适应各种复杂的安装环境。

退火工艺是本产品制造过程中的关键步骤，通过控制加热温度、保温时间和冷却速度等参数，达到钢管组织的均匀性和性能的稳定化。退火后的钢管硬度低，塑性好，便于后续加工安装。此外，其电阻率低，导电性能优良，保证了高精度信号的传输质量。同时，还具有优良的力学性能和高温性能，具有足够的机械强度，不易变形。应用范围十分广泛，在石油工业中，由于其强度高、耐腐蚀、耐高温等特点，被广泛应用于原油输送、加工及石油钻探、油田开发、油气管道等领域。在化工工业中，由于其耐腐蚀性能优良，能抵抗酸、碱、盐等腐蚀介质的侵蚀，常用于蒸馏塔、石油化工设备、化肥设备等重要部位。也适用于简易家具、婴儿车、仓储架、农棚、游乐设备、健身器材等生产。

 当然，我们产品的质量是毋庸置疑的，我们已获得KS、JIS和ISO9001国际认证。而且我们的生产效率也很高，月产量约5000吨。最低订购量为20吨。一般情况下，我们的交货时间为31-45天，如果需求量极大或出现特殊情况，可能会延迟。对于包装方式，我们在装载和运输时会为各种钢材选择合适的包装和加固。如果您有任何其他问题，请随时与我们联系。https://www.shaiyia.com/

Black annealed steel pipe, also known as black annealed pipe, is a type of steel pipe that has been annealed at high temperatures. This type of steel pipe is made without any surface treatment, so the surface color is blackened by exposure to air at high temperature, and the surface is not brightened, giving it a black appearance. Its production process is simple and it is usually used in applications that do not require high surface finish and accuracy. Black annealed steel pipe is made of high quality carbon structural steel as raw material and precision processed. The products are characterized by smooth inner and outer walls, high dimensional accuracy and uniform structure, which ensure good fluid transportation capacity and stability. In addition, the annealed steel pipe has excellent toughness and ductility, which can be adapted to various complex installation environments.

Annealing process is the key step in the manufacturing process of this product. By controlling the heating temperature, holding time and cooling rate and other parameters, to achieve the uniformity of the steel pipe organization and stabilization of properties. The annealed steel pipe has low hardness and good plasticity, which facilitates subsequent processing and installation. In addition, it excels in electrical conductivity with low resistivity, which ensures the transmission quality of high-precision signals. At the same time, it also has excellent mechanical properties and high temperature performance, with sufficient mechanical strength, and not easy to deformation. It has a wide range of applications. In the petroleum industry, it is widely used in crude oil transportation, processing and oil drilling, oil field development, oil and gas pipelines and other fields, thanks to its high strength, corrosion resistance and high temperature resistance. In the chemical industry, due to its excellent corrosion resistance, it is able to resist the erosion of corrosive media such as acid, alkali and salt, and is commonly used in distillation towers, petrochemical equipment, fertilizer equipment and other important parts. And it is also suitable for the production of simple furniture, strollers, storage racks, agricultural sheds, play equipment and fitness equipment.

 Of course, the quality of our products is unquestionable. We have obtained KS, JIS and ISO9001 international certifications. And our production efficiency is also very high, with a monthly output of about 5000 tons. And the minimum order quantity is 20 tons. In general, our delivery time is within 31-45 days, and may be delayed if the demand is extremely large or special circumstances occur. For the packaging methods, we choose suitable package and reinforce for various steel products when loading and transport. If you have any further questions, please don’t hesitate to contact us. https://www.shaiyia.com/
