Chain fittings are forged from carbon and alloy steel of grades 8, 10, and 12 per ISO 898-1. Their surface hardness ranges from 35 to 45 HRC for optimal strength-impact resistance balance. Dimensions are designed for compatibility with chains of 6 to 40 mm diameter. Safe Working Load WLL ranges from 0.5 to 30 tons with a 4:1 or 5:1 safety factor as per EN 1677-1. All components undergo quench and temper heat treatment for uniform mechanical properties. Quality control includes dimensional checks, magnetic particle testing MPI, and random tensile sampling.

Primary types include grab hooks, clevis hooks, master links, shackles, and turnbuckles. Geometric design follows standard angles of 60, 90, or 120 degrees for chain and load compatibility. Common surface coatings are hot-dip galvanizing 60–80 microns or electrostatic epoxy powder for corrosive environments. Laser engraving or labeling with technical data WLL, material grade, serial number is mandatory. These fittings are suitable for operating temperatures from –40°C to 200°C in oil & gas, maritime, and construction industries. Production complies with international standards ISO 2415, EN 1677, and ASME B30.26.You can order and buy Accessories from Iran by contacting us through whatsaap and email.

Connecting Chains of Different Calibers to Each Other

Directly connecting chains of different calibers strength grades is strictly prohibited. This practice causes stress concentration and uneven load distribution. The lower-grade chain acts as a weak link, increasing the risk of catastrophic failure. For a safe connection, intermediate links or fittings with a load capacity matching the strongest chain must be used. The connector must have certification and a strength grade compatible with the stronger chain. Any connection should be supervised by a qualified engineer and comply with recognized standards. Labeling and documenting the specifications of each part of the connection system is mandatory. This approach maintains operational safety and the integrity of the load-bearing system.
