Mast Raising Lines

  Fatigue resistant

  Meets API Specifications

  Proof Tested

Mast Raising Lines, also called Bull Lines or Bridle Lines, are usually two pieces: each having sockets on both ends. These lines can be fabricated from either right regular lay rope or right lang lay rope. They must be fabricated from IWRC ropes. Use the chart below to select grade. Refer to the product bulletin (below) for more information concerning actual constructions.

 

Rotary Drill Lines

 

6x19 IWRC Conventional Drill Line

  Standard Drill Line

  Meets or exceeds API 9A


This demanding application requires a rope that is abrasion resistant, crush resistant, fatigue resistant and relatively stable.

Premium ropes may be used for specific applications. PFV cushions the strands, distributes internal stresses, keeps in wire rope lubricant and keeps out dirt and debris, extending the service life.

                                                                                                                                                                                   

TUF-FLEX Drill Line

  Superior performance 6-strand rope

  Increased service life

  Less sheave and drum wear

  

Rotary drilling line applications require a rope that is abrasion resistant, crush resistant and fatigue resistant.

The process used during the manufacturing of TUF-FLEX DL compacted drill lines provides a smooth wire rope with greater surface area and more steel per given diameter, which increases strength, fatigue resistance and wear resistance.

Our TUF-FLEX DL compacted drilling lines have a plastic impregnated core which minimizes internal nicking and prolongs service life of the rope.

Compacting process increases surface area

The increased surface area of compacted rope can be seen in the comparison of the contact points of a standard 6 x 26 WS (left) and the compacted rope (right).

 

 

 

 

 

 

6-Strand PFV

  Abrasion resistant

  Fatigue resistant

  Plastic polymer cushions strands, distributes internal stresses and keeps dirt out

Backed by a service-proven reputation, these ropes are built tough to withstand abrasion and fatigue.

6-Strand PFV ropes are plastic impregnated with plastic polymer applied at high pressure which cushions the strands, distributed internal stresses, keeps in wire rope lubricant and keeps out dirt and debris. This polymer doesn’t melt or soften from the heat of normal operating temperatures. It’s also virtually unaffected by sunlight and cold weather.

TUBING LINES

6x31 Swaged 6x31 Swaged Wire Rope Construction

  High density construction for greater crushing and abrasion resistance

  Greater strength

Well servicing rigs must work wherever producing wells need servicing. One of the primary ropes on these mobile rigs is the tubing line.
                                                                                                                                 The tubing line operates on the main draw works and is reeved through the traveling block for handling tubing and rod. Often the tubing line is rigged with both ends attached to the drum with one end spooling on the second layer of wraps immediately adjacent to the other end spooling on the first layer of wraps. This is called “double fast line” spooling and is done to speed up travel time of the main hoist during rod and tubing pulling operations.

When you purchase Union tubing lines, you get more than what meets the eye. Built in an ISO 9001 certified factory and backed by the industry’s largest staff of professional engineers, we do more than produce to spec.

Our quality begins with our raw material qualification process which suppliers must meet standards that are more stringent than industry. We then document rod coils though completion rope manufacturing for full traceably. We don’t stop there; the traceability continues into the field as each schedule is tracked to the customer. Throughout the manufacturing process we break test wires and tie that information to the coil and/or reel of rope. Thus ensuring we know the characteristics of the rope from its infancy and know it meets or exceeds our published strengths.

 

 

 

 

 6x26 Tubing Line IWRC

  Compact construction

  Crush resistant

  Excellent fatigue resistance

The 6x26 WS features a compact construction with solid support for the wires; therefore it has a high resistance to crushing and well suited for tubing lines. Its number and relative size of the inner wires add to the stability of the strand and gives it excellent fatigue resistance. Since the “double fast line” is often used to speed up travel time of the main hoist during rod and tubing pulling operations, fatigue resistance is an important benefit.

Flex-X 9

  Crush resistant

  Abrasion resistant

  Greater surface area 

Flex-X 9 features compacted strands and swaging for extra drum crushing resistance and increased stability. Its high density strands deliver extra strength and resistance to abrasion. Flex-X 9 is manufactured with a dual compaction process to produce a compact cross-section with minimum voids and greater surface area on outer wires that contact drums, sheaves and the rope, itself during operation. The high-density compacted strands minimize nicking at strand-to-strand contact points. Flex-X 9 was specifically designed for boom hoist applications and tubing line applications where drum crushing is a challenge.

Flex-X® vs. standard rope of similar construction:

Flex-X designs reduce drum scrubbing between the lead line and the previous wrap. The smooth contact creates less interference, less metal loss and wire deformation. The increased surface area of Flex-X can be seen in the comparison of the contact points of a standard 6x26WS and Flex-X as shown.

  

Sand Lines

6x7 FC

  Designed  for  harsh  conditions 

  Excellent abrasion resistance

  Larger outer wires

The vast majority of this market utilizes a 6x7 Bright Fiber Core. In a 6x7 rope, the wires are larger than those of other constructions of the same diameter. Wires of a 6x7 are approximately twice the diameter of outer wires of a 6x25 FW rope. The large size of the outer wires gives this class excellent abrasion resistance –at great sacrifice of bendability and resistance to fatigue. The standard 6x7 rope construction is made with fiber core and right regular lay.

 

5x7 FC Swaged

  Compacted swaged design provides greater strength per diameter

  High density construction for greater crushing and abrasion resistance

  Compact cross section for greater surface area, less scrubbing, longer wear

We have access to Union's sandlines, the largest inventory of sandlines in North America in 1/2”, 9/16” and 5/8” diameters.

Under normal conditions our 5 x7 Fiber Core (FC) lines have proven to be an economical tool for extending service life. These workhorses of the well servicing industry are available in both standard and swaged construction.

 

 

  6x7 Galvanized

★  Provides longer service in hostile down-hole conditions

★  Excellent abrasion resistance

★  Operates smoothly and cleanly

Where extremely corrosive conditions shorten the service life and effectiveness of bright sand lines, the WRCA 6x7 galvanized delivers the goods. Zinc-coated to perform better in hostile down-hole conditions, our 6x7 galvanized sand line reduces rope changes, downtime, and increases productivity.

 

★  Exploration/Core Drilling

Drill Lines

 

3x7 Swaged

★  Provides longer service in hostile down-hole conditions

★  Excellent abrasion resistance

★  Operates smoothly and cleanly

These 3-strand ropes are ideal for diamond drilling operations. The 3-strand compacted design provides resistance to rotation while also providing a high strength/weight ratio. Compacting the rope also results in an exceptionally dense cross-section. This increases surface area, which improves rope contact with sheaves and drums, thereby providing greater resistance to surface wear and abrasion while reducing wear on sheaves.

 6x36 IWRC

★  Fatigue resistant

★  Abrasion resistant

The 6x36 classification of wire ropes includes standard 6 strand, round strand ropes with 27 through 49 wires per strand.

The 6x36 ropes are important for their fatigue resistance. This fatigue resistance is made possible by the greater number of small wires per strand.

Although there are exceptions for special applications, the constructions in 6x36 classification are primarily designed to be the most efficient for each rope diameter. As the rope size increases, for instance, a large number of wires can be used to achieve required fatigue resistance, and still those wires will be large enough to offer adequate resistance to abrasion.

Characteristics of Standard 6 x 36 Class ropes

In most rope sizes, only one 6 x 36 classification rope is made. These constructions were selected to provide fatigue resistance without having wires that are too small.

The greater number of wires in the 6 x 36 classification makes these ropes more susceptible to crushing. This can be minimized, however, by specifying an Independent Wire Rope Core (IWRC) and by using well designed sheaves, grooved drums and proper operating techniques.

 

 

Guide Line

 

6x26 WS IWRC

  Fatigue resistance comparable to a 6x25FW

  Recommended in any application where a 6x25FW is used

The 6x26 WS has better resistance to abrasion than a 6x25FW. It features a compact construction with solid support for the wires; therefore it has a high resistance to crushing. Its number and relative size of the inner wires add to the stability of the strand and gives it a fatigue resistance comparable to a 6x25 FW. A standard 6X26 WS construction provides the best rope for a wide range of applications. In general, we recommend the use of the 6x26WS in any application where a 6x25FW is used.

Flex-X 6

  Superior performance 6-strand rope 

  Increased service life 

  Less sheave and drum wear 


Flex-X 6 users receive superior performance and increased service life in many applications compared to the ropes they had previously employed. When compared to conventional six strand ropes, Flex-X 6 ropes provide greater surface area and more steel per given diameter. This increases rope stability and strength. This results in a longer service life and less
sheave and drum wear.
