Chemical composition analysis: By analyzing the chemical composition of the steel pipe samples, the content of each element can be determined to ensure that the steel pipe material meets the requirements of relevant standards and specifications.
Mechanical performance testing: By conducting tests such as tensile testing, impact testing, and hardness testing, the strength, toughness, and hardness of the steel pipe material can be evaluated.
Metallographic observation: By using a metallographic microscope, the grain structure, phase content, and grain boundary characteristics of the steel pipe can be observed to evaluate its structural properties.
Corrosion performance testing: By conducting tests such as salt spray testing and corrosion rate testing, the corrosion resistance of the steel pipe can be evaluated to ensure its service life in specific environments.
Dimension and appearance inspection: The dimension, shape, and surface quality of the steel pipe are inspected to ensure compliance with specified dimensional and appearance requirements.
Car manufacturer achitechive Machining
1. Precision manufacturing: Cold-drawn seamless steel tubes are manufactured through the cold drawing process, which guarantees dimensional accuracy and smoothness. The surface has high finish, and the inner and outer walls are defect-free, meeting the requirements for high-precision applications.Our tolerance can be guaranteed at ±0.1mm.
2.Excellent mechanical properties: During the manufacturing process of cold-drawn seamless steel tubes, the material undergoes plastic deformation, resulting in grain refinement and improved hardness and strength. Compared to hot-rolled seamless steel tubes, cold-drawn seamless steel tubes have higher tensile strength, compressive strength, and impact resistance.
3.Good surface quality: Due to the characteristics of the cold-drawing process, cold-drawn seamless steel tubes have better surface quality. The surface is smooth and flat, with no obvious scales or oxidation, meeting the requirements for high-quality surface treatment and coating.
4.Wider range of applications: Due to its precision manufacturing and excellent mechanical properties, cold-drawn seamless steel tubes are widely used in industries such as mechanical manufacturing, automotive manufacturing, petroleum and natural gas industries, petrochemical industry, high-temperature and high-pressure fields, and structural engineering.
In summary, cold-drawn seamless steel tubes have advantages such as precision manufacturing, excellent mechanical properties, and a wider range of applications. Therefore, they are widely used in industries with high requirements for tube quality and performance.
1.What is your paying terms?
Our usual paying terms are 30%TT as deposit and balance paid after seeing copy of bill of loading. For clients cooperated for more than one year, we accept 20% prepay. Beside we do business also under D/P and LC terms.2.How long is your delivery time?
For the goods we have in stocks, we deliver the goods within 5days. If it is a production order with volume not above 200tons, the delivery time will usually be within 20days after sealing contract. And the delivery time shall be slightly longer for order volume above 200tons.
3.Can you do partial shipment?
We will follow client request to do partial shipment or not. Partial shipment is not a problem for us.
4.What is your Minimum Order Quantity?
For goods in stocks we supply starting with one piece. Shall it is a production order, the MOQ is 3tons. Please be noted price based on MOQ will be slight higher than FCL condition due to higher unit cost.
5.Before cooperation we want a sample for inspecting of quality, is that okay?
We can provide a free sample for you shall sample value not above 30USD, you only need to pay the express charge. For a sample valued more than 30USD, the express charge and just one half of sample value is on the account of you, and we afford the other half.
6.What is the mode of transportation?
Ocean freight is the most important shipping way, and we choose the ship line based on soonest and earliest shipping time, rather than cheaper cost; or we follow clients ' instruction if there is one. Also railways will be chosen by us when it is more convenient. For samples and papers, the transportation will be by air.
