Catalogues and
Technical Guidelines

Blue Wave is ISO 9001:2015 certified and produces high quality stainless steel fittings and rigging screws ranging from ø 2 mm and up to ø 36 mm / 1/16” – 1-3/8” wire.

Serving various industries world wide we have divided our range into four main groups and catalogues.

All our products are inspected and in house tests are made to demand. Certificates are issued against order and destructive inspection tests can be made to order.

We believe no market or customer is the same and rely on the expertise of our international partners. With them we serve and act to local market demands and encourage new ideas and solutions.

As a general assistance please find overview of our catalogues and general technical instructions below.

The Blue Wave product range is divided into separate catalogues with each their focus.

The Marine catalogues features UNF and Metric wire fittings ranging from Ø 2 mm – Ø 26 mm, a rod system up to DASH 60 as well as various rope – and other marine related items.

The Wire Design System mainly features Metric wire fittings from Ø 2,5 mm up to Ø 36 mm a Tie-bar system and a range of SMALL fittings with reduced diameters.

WaveLine contains ranges of 8 mm / 5/16” fittings for Fall Arrest System – standard swage, Hand-crimp and Lloyds Swageless wire attachment.

The RopeLine catalogue contains a range of UHMWPE rope fittings up to Ø 16 mm. The product range can be combined with other Blue Wave products – marine as well as industrial.

Blue Wave production is ISO:9001:2015 certified

To achieve maximum break load Blue Wave recommends pressing or swaging/rolling the terminals onto the wire ropes. Recommended machines for this purpose are e.g. Presses from TALURIT® and roller swaging machines from WIRETEKNIK. Terminals from Blue Wave are also suitable for rotary hammer pressing! WDS Break Loads See the swaged dimension chart for further details to individual wire – and terminal sizes!

If the exact length of the final wire is unknown a good solution is to swage the wire one end, while applying a swageless terminal on site at the other end. Alternatively the Wire Design System offers a full range of Small fittings that can be hand crimped onto the wires. With the small fittings a 50% break load of the wire can be achieved. Optimal Break loads with Blue Wave rope fittings is achieved following the splice instruction given by the rope manufacturer in question. The rope fittings are designed to be stronger than the spliced rope. When planning a wire construction the ultimate break load, as well as the work load, must be calculated, as it will determine the minimum wire size and maybe the wire construction needed. Blue Wave’s fitting’s, unless otherwise stated, are constructed after termination to meet 90% of the break load on the wire ropes that are standard in the market. PLEASE NOTE: In order to guarantee safety in a wire construction you should calculate a safety factor of 2-3 on static constructions and a minimum of 5 on dynamic constructions. As a general rule working loads should never exceed 20% of the break loads stated in this catalogue.

When tensioning a wire the wire will stretch and this need to be taken into consideration during calculation.

Stretch is the degree of a material to which it is able to be lengthened by pulling and can be of two types:

  1. Structural Of a permanent character. Caused when the initial load is applied.
  2. Elastic (ES) Given by the applied load (kN), wire length (mm), modulus of elasticity of wire and it’s cross sectional area ( diameter2 x Pi/4 ) It is possible to calculate this value from the formula:

Elastic Strech – mm = Applied load (kN) x Length (mm)
                            e-modulus (kN/mm²) x cross section (mm²)

As well as serving as an attachment to a given construction, threaded terminals attached to both ends of a wire, can serve as a tensioner. Where tension cannot be applied to the thread via a nut at each end, the wire can be tensioned by use of e.g. right handed and left handed thread terminals at each end of the wire – by turning the whole wire tension will be applied.

To ensure prober tension Blue Wave as a rule of thumb recommends the following maximum wire lengths.

How to Keep Stainless Steel Stainless – Words of an Expert

Stainless steel is a wonderful material, and treated properly, it will stay bright and stainless forever. Sadly, natural saltwater is one of the most aggressive and corrosive media towards stainless steel, and even the ”acid resistant” 316L class requires a bit of maintenance in order to stay stainless.

In case of 316L above water, the main issue is time. Saltwater is very aggressive towards virtually any alloy, and the key issue is to keep the contact time as short as possible. In wet, temperate conditions, such as Scandinavia, the Canadian West Coast or the South Island of New Zealand, the all-too-common rain takes care of this, however, in warmer and drier conditions, such as Southern Europe and The Middle East, things are much different. Here, all saltwater sprayed onto the steel from below will tend to stick to the steel forever, with little chance of rain from above. Similar conditions are observed in dry season in the Caribbean, the tropical Pacific, or in South-East Asia. In the wet season, these places receive large amounts of rain, rendering any freshwater cleaning superfluous.

Very likely, the saltwater will cause superficial pitting corrosion, and although such attacks may not cause operational failure, it certainly looks unattractive and should be avoided. The best and cheapest way to avoid pitting corrosion is to keep the contact time low. Cleaning off the saltwater as quickly as possible keeps the contact time short, and the risk of corrosion correspondingly low. The more frequent the freshwater rinse, the better, and, presumably, a thorough rinse every fortnight should do the trick.

Be particularly aware that fittings below a braided steel cable are particularly prone to collecting saltwater, and so is the braided cable itself. Due to gravity, the upper fittings (pointing downwards) are less exposed to saltwater and may be rinsed less frequently.

If freshwater is not available, the second-best solution is to rinse with saltwater and dry the steel immediately afterwards. It is, still, preferable to use low-chloride water (i.e. freshwater) as often as possible.

Blue Wave High Quality Lubricant To ensure good performance and long life Blue Wave next to general maintenance recommends that threads are regularly lubricated. We recommend a synthetic oil based lubricant with PTFE.

Synthetic oil based Lubricant with PTFE

The Blue Wave Lubricant contains PTFE micro powder, dispersed in synthetic base oil with anti-oxidation additives.

It is high effective lubricant, with long life properties, for use in metal to metal applications. Water repellent, do not soil, resists temperatures between – 50°C and +200°C. The Blue Wave Lubricant is non ageing and has extremely low friction and is used on the threads improving the performance. Whenever stainless steel threaded parts are screwed together it is always strongly recommended to lubricate the threads first, as this prevents the threads from jamming!

Supplied in tube with 5, 30 and 50 gr.
