Petrochemical Cable Ladder Stainless Steel 316L 200mm-700mm Width Pickled

Petrochemical Cable Ladder Chemical Resistant is specified for refineries, tank farms, chemical plants and fertiliser units, where the cable route is exposed to hydrocarbon vapours, acid mist, washdown chemicals and a corrosive atmosphere that shortens the life of an ordinary galvanized ladder.

The ladder is produced in 316L stainless steel as the default for chloride and acid service, with 304 stainless, aluminum and hot dip galvanized steel as alternatives, in 200 mm to 700 mm widths, 100 mm to 150 mm rail height and rung pitch of 225 mm or 300 mm. Modules of 2 m and 3 m with a full fitting family allow the route to follow a congested pipe rack.

The material choice is driven by the specific chemical exposure: 316L with molybdenum resists chlorides, dilute acids and sour service, while for strong acids and hypochlorite a pultruded FRP ladder is the better answer because the composite is immune to electrochemical attack. Our engineers will advise which is appropriate once the chemical list is known.

Petrochemical routes also carry fire and earthing requirements. The steel ladder is non combustible and keeps the earthing path continuous through bonded couplers, while the composite version is used where an insulating support is required and where no metal path is wanted in the process area.

BENDIN manufactures this family at 7000 m per working day with 180 staff and thirty years of cable support experience in the process industries, exporting 60 to 70 percent of output to petrochemical and energy contractors. Material certificates, weld records and coating test results are provided with every shipment.

Minimum order 600 pcs, 25 working day delivery, 10 to 30 USD per piece, pallet packing, terms L/C, D/P or T/T. Give us the chemical exposure list, the area classification and the load and we will confirm the material grade, the fasteners and the support spacing.

BENDIN holds ISO 9001 quality certification and issues CE Declarations of Conformity. The standards above state the design and test basis of this product; third party test reports or national approvals are supplied on request and are not implied unless confirmed in the contract.

Dimensions, rung spacing and surface treatment are produced to project drawings. Load and deflection calculations are issued for spans above 3 m.

Q: Which material for chloride and acid service?
A: 316L stainless handles chlorides, dilute acids and sour service. For strong acids or hypochlorite we recommend pultruded FRP, which is immune to electrochemical attack.

Q: Are fasteners and welds treated?
A: Welds are pickled and passivated and A4-70 stainless fasteners are used, so the joint does not become the first corrosion point.

Q: Does the ladder suit a classified area?
A: Yes, with installation guidance to IEC 60079 practice for the area classification, and documentation supplied for the safety file.

Q: What is the minimum order?
A: Minimum order 600 pcs, delivery 25 working days, prices from 10 to 30 USD per piece.
