What factors should be considered when selecting an ASTM A193 B7 eye bolt for petrochemical applications?

Our company has a vast collection of eye bolts, famous for their distinctive loop (or “eye”) at one end. An ASTM A193 B7 eye bolt easily connects cables or ropes in structural applications. These externally threaded fasteners can lift high loads and deliver sustained performance (when selected carefully).

Petrochemical applications like oil and gas drilling demand durability, tolerance toward high temperature and pressure, and corrosion resistance. AISI 4140 A193 B7 machinery eye bolts can endure temperatures up to 450°C and withstand many chemical solvents. Buyers should also consider:

  • Compliance with international standards like ASTM and ISO
  • Fatigue resistance
  • Protective coating of zinc, cadmium, xylan, PTFE, etc.
  • Ease of installation and inspection

An SA193 B7 eyelet bolt and stud fasteners with threading on both ends help workers to ensure safety in petrochemical applications.

What are the different testing requirements for exporting SA 193 Grade B7 eyelet screws?

Export requirements for SA 193 Grade B7 eyelet screws mandate top-notch quality and performance. This specification does not include extensive testing procedures, but we prioritise thorough examination to guarantee client satisfaction. Export documentation requires an MTC (Mill Test Certificate), details on country of origin, and quality tests.

  • Proof load test to check the maximum amount of force it can withstand without deforming
  • Tensile testing
  • Ultrasonic examination to diagnose structural defects
  • Hardness assessment

We can also accommodate additional destructive and non-destructive processes or a third-party examination by accredited laboratories.

How does the thickness of A193 B7 Lag Eye bolts impact their performance?

Threading plays a pivotal role in the performance of these fasteners, with finely threaded bolts stronger than coarse ones. The former has a larger tensile stress area. But the thickness of A193 B7 lag eye bolts also matters, affecting the tension you can apply. Bolts with larger diameters can deliver better performance.
The standard sizes are M8 to M100. We can deliver these products in lengths of 6 to 48 mm or per client demands.
