Pipe connectors

About the system

KLEMP pipe couplings are innovative and versatile products for the construction of safe balustrades, handrails, barriers and much more, both in industry and in the private sector. KLEMP couplings allow easy and very fast connection of standard pipes for the construction of modular steel and aluminum structures.
KLEMP couplings are elements that allow extremely flexible implementation of solutions. Despite their simplicity, they are very effective and have proven themselves over the years in thousands of projects all over the world. The KLEMP system safely combines standard sizes of steel and aluminum pipes in almost any layout imaginable, using the widest range of pipe couplings available on the market today.
The couplings are made of hot-dipped galvanized cast iron, giving them high corrosion resistance and long service life.

Why KEMP couplings?

Steel and aluminum pipes have been used as a construction element for many years. They are durable, have no sharp edges and are readily available anywhere in the world. The problem with using steel and aluminum tubing to build various structures is the issue of connections. Threaded pipe must be delivered to the job site in a precisely defined size and offers virtually no flexibility in installation. Welding requires skilled personnel, is a complicated and time-consuming process, and requires specialized equipment.

Design

Central to the design principles of the KLEMP system is the principle of realizing a quick and easy connection of pipes. Our connectors provide the versatility to build any design. The KLEMP system consists of cast iron, galvanized connectors. We have developed a wide range of connectors in six different sizes. The hexagon socket clamping screw provides a secure and tight connection to the pipe. Stainless steel screws are available upon request.

Simplicity

KLEMP pipe couplings are easy to assemble and disassemble with an Allen wrench, reusable.

The pipe couplings are fixed with a hexagon socket screw. In this way, any desired design can be perfectly realized, whether it is complex or rather simple - the possibilities are almost unlimited, as the choice of different types of pipe connections means that almost anything is possible, whether you are working with aluminum or galvanized steel pipes, as long as the correct diameter is maintained.

Thanks to the simple design, our connectors allow for very quick assembly, which significantly reduces labor costs.

    What material are the tubefittings made of?

    Tubefittings are made of cast iron. They come in galvanized, raw and powder-coated versions.


    Is the given diameter the inner diameter of the tubefitting or the diameter of the congruent tube?

    All tubefittings are marked with a size that corresponds to the dedicated tube diameter. For example, in the case of D - 42 mm tubefittings, the diameter of the tube dedicated is 42 mm. It is worth noting that each tubefitting features a certain clearance, as the tube is assembled inside the tubefitting with the use of a dedicated set screw. Therefore, a slightly smaller or larger tube should be about fine.


    I have a slightly larger/smaller tube. Is the mounting possible with the use of your tubefittings?

    Yes, a small additional clearance (1-2 mm) can be compensated by a set screw being screwed into the tubefitting. Such clearance does not affect the stability of the final structure.


    Are the tubefittings suitable for outdoor or indoor use only?

    For external use, we recommend the use of galvanized (silver) fittings. Tubefittings in black paintwork are powder coated, but they are not covered with a zinc layer, so we cannot give a 100% guarantee for long-term weather resistance. Natural tubeclamps, on the other hand, do not have any coating, they are raw. Natural tubeclamps are easy to paint or they can be used in highly designer projects in which the customers want to achieve the effect of rust and corten steel.


    Can the fittings be painted in a different colour?

    We do not provide this service ourselves, but you can paint the fittings yourself (preferably powder coating). For better corrosion resistance, we recommend powder coating of galvanized fittings.


    What method is used for zinc plating of the fittings (galvanizing or hot-dip galvanizing)

    Galvanized fittings are hot-dip galvanized, which ensures appropriate thickness and durability of the coating


    Are hex set screws included (with a purchased fitting)?

    Yes, all tubefittings are supplied with set screws as standard. If necessary, they can also be ordered separately.


    What is the maximum load of the tubefittings

    Each set screw in a tubefitting can bear a shear load of about 600 kg per piece at a tightening torque of 40 Nm.

    We will be happy to answer all your questions and help you make a decision, but we take no responsibility for the safety of the structure.


    How are the tubes fixed in the tubefittings

    Tubefittings are supplied as standard with set screws, which can be tightened firmly with the use of an appropriate hex key.

    Tubefittings are clamped on the tube with the use of a set screw screwed-into.


    What kind of a hex key do I need?

    The following hex keys fit the given sizes of the tubefittings:

    • Size A = (21.3 mm diameter fitting)
    • Size BC = (fittings with a diameter from 26.9 mm to 33.7 mm)
    • DEF size = (fittings with a diameter from 42.4 mm to 60.3 mm)

    What are the tubefittings' threads?
    • - 21.3 - G 1/8" x 10 mm BSP
    • - 26.9 and 33.7 - G 1/4" x 12.5 mm BSP
    • - 42.4/48.3 and 60.3 - G 3/8" x 12.7 mm 19 BSP

    Why is there sometimes clearance between the tubefitting and the tube?

    This is due to the fact that the tubes may have a minimum tolerance of inner and outer diameter. This also applies to tubefittings. Since the tubefittings are made of cast iron and then hot-dip galvanized, there may be a slight difference between them. This difference is ultimately necessary to ensure that the tube and tubefitting can be connected. This clearance does not affect the strength of the structure.
