Table Of Content
Alloy properties-
This grade is combined with high tensile and impact strength. It has a low coefficient of thermal expansion and has higher thermal conductivity. It has many prominent properties suitable for many structural and mechanical components. These alloy posse’s good mechanical traits in low, ambient and elevated temperatures. This alloy is processed from the annealed and quenched condition. This alloy is not recommended for application in the exposure to higher temperature up to 570 deg F, due to the increased risk of reduction in toughness.
The high alloying chemistry makes it extremely resistive to uniform corrosion in organic compound environments like acetic acids and formic acids
BS 3059 Gr.360/440 Tubes provides excellent resistance to inorganic compounds, especially which has a high level of chlorides. These tubes are highly alloyed specially designed to resist concentric sulfuric acids. However, these tubes cannot be used in hydrochloric acids because of the risk of local and uniform corrosion. These tubes can be used in the moderate hydrochloric acid containing environments. Pitting and crevice corrosion is not an issue in these tubes.
Quality control and testing-
We have always pounded and followed strict quality standards for all manufacturing operations. The material used in the manufacturing process is well tested and examined. The technical guidelines and industrial design codes are followed to achieve the highest standard of quality.
We have a quality control team that supervise quality assurance and control aspects along with the manufacturing process. Quality control examinations are regularly conducted in order to maintain consistent and uniform product quality.
Those tests are destructive type tests and non-destructive type tests.
Destructive type tests-
• Tensile test
• Mechanical test
• Compression test
• Pressure test
• Leakage test
• Thermal performance analysis
• Hardness test
Non-destructive type tests-
• Intergranular corrosion test
• Positive material test
• Pitting corrosion test
• Ultrasonic test
• Radiography
• Chemical analysis
• Micro test
• Macro test
All our range of products is supplied with essential reports and certificates that show our quality. Customers also use the manuals and guides for effective use of products. Mainly these reports are national board approval lab (NBAL) test report, specification guide, welding guide, quality assurance plan, mill test report, and more.
We have a prominent dispatch system that guarantees 100% safer delivery. Our professionals pay special attention in this section. BS 3059 Gr.360/440 Tubes are supplied in the form of big bundles with the additional support of end caps. Moreover, each packing is covered by a thin film of plastic that adds protection from contamination and rusting while exporting.
