R500 Curvature Galvanized Cable Bend Board for 130mm Max Cable Diameter Wellhead Cable Bend Board Chute

What the Bend Board Does

Where cable leaves or enters a wellhead it has to follow a curve, and the structure around the wellhead is rarely built to that curve. The JKD series bend board is a galvanized steel chute that sits in the cable path and provides a fixed curvature of R400 or R500 so the cable is supported through the turn instead of being bent over a structural edge. Four models cover maximum cable diameters from 80mm to 150mm, with weights from 5KG to 6.5KG.

Model table

Reading the curvature column

• The curvature diameter sets the smallest bend the board will hold the cable to. Match it to the minimum bend radius allowed for the cable type, not to the space available.
• The 80mm and 100mm models are listed at R400; the 130mm and 150mm models at R500, so the curve opens up as the cable gets larger.
• Maximum cable diameter is the hard limit for each model. A larger cable will not seat in the chute whatever the curvature.
• Board weight is low enough for one person to handle, but confirm the fixing method at the wellhead before the pull is scheduled.

Fitting practice

Fix the board so both ends sit tangent to the cable path; a board that meets the cable at an angle simply moves the bend to its lip. Support the underside so the chute does not flex under pull load. On reused boards, check the galvanized surface for burrs at the edges and for any build up of grit in the channel, then wipe the contact face before the next pull. Where the cable is close to the model limit, keep the contact length on the curve as long as the site allows.

Inspection before dispatch

• Galvanized surface checked for bare patches and edge burrs.
• Channel curvature sampled against the model's R400 or R500 specification.
• Weight confirmed against the table row.
• Plywood case packing with the channel foam protected, 500 PCS per month supply capacity.
• One year warranty against manufacturing defects under normal site use.

What the page does not claim

The four item numbers, curvature diameters, cable limits and weights above come from the current JKD datasheet. This page does not publish a wear or life figure, does not claim the board replaces a bend radius calculation for the cable, and does not state a certification beyond the ISO entry in the attribute table. Galvanized finish is stated because it is on the datasheet; where a project needs a coating thickness report, request it with the enquiry.

Buyer questions

Which board suits a 130mm cable?

JKD130, item 21306, listed at R500 curvature with a 6KG weight.

Is a bend board the same as a roller?

No. A roller turns under the cable; the bend board is a fixed chute. Choose the board where a stable curve is wanted and the roller where friction has to be minimised over a long pull.

Can two boards be used in series?

Where a longer curve is needed, confirm the arrangement with the enquiry so the tangent points line up.

What are the order terms?

1 PCS minimum order, L/C or T/T, 3-7 days for stock, plywood case packing.
