Leasing & Hire Purchase
Leasing & Hire Purchase
We offer the financing options leasing and hire purchase exclusively to businesses, commercial operators and self-employed persons for selected products with a net order value of €1,000 or more. Below you will find the key differences between the two forms of financing.
Leasing
With leasing, the product is made available to the lessee for use in return for regular lease payments. The asset is recognized on the lessor’s balance sheet. Lease payments can generally be claimed as operating expenses for tax purposes. These are gross payments, and VAT is charged throughout the entire term. Once the agreed minimum lease term has expired, purchasing the product is generally possible.
Hire purchase
In economic terms, hire purchase is equivalent to an installment purchase. The product is capitalized on the hire purchaser’s balance sheet and depreciated in accordance with the official depreciation tables. Ownership of the asset transfers to the hire purchaser upon payment of the final hire-purchase installment. VAT must be paid in full with the first hire-purchase installment (a pass-through item).
Shipping & Delivery
Shipping & Delivery
We ship our goods either via parcel service or via a freight forwarding company, depending on their size, weight and characteristics. We select the shipping method at our reasonable discretion.
The delivery times stated in the online shop are non-binding estimates, unless a binding delivery date has been expressly agreed in writing. They are based on the information available from our manufacturers, suppliers and logistics partners at the time the order is placed.
A large proportion of the products offered are shipped directly from the manufacturer or from external central warehouses (direct shipment). As a result, delivery times may differ from the stated guidelines. In particular, material shortages, production delays, supply bottlenecks, force majeure or other circumstances for which we are not responsible may result in delivery delays.
Disclaimer:
We accept no liability for delivery delays resulting from circumstances beyond our control. This applies in particular to delays caused by manufacturers, upstream suppliers, transport companies or other third parties. Liability for any resulting damages, in particular indirect damages, consequential damages or loss of profit, is excluded to the extent permitted by law.
Partial deliveries are permitted insofar as they are reasonable for the customer. They will not result in additional shipping costs unless otherwise agreed.
The exact delivery time for an item can be provided individually on request, either before or after placing the order.
Please contact us by telephone at +49 (0)2551 5030 or by email at shipping@strahltechnik-express.de.
If significant delivery delays occur, we will inform the customer without undue delay. Mandatory statutory rights of the customer remain unaffected.

Clemco Hollo Blast Junior – internal pipe blasting unit for 19 to 50 mm pipe ID
The Clemco Hollo Blast Junior was developed for internal processing of small pipes with internal diameters of 19 to 50 mm. A special deflector head distributes the blast against the internal pipe wall, enabling the removal of rust, scale, and contaminants in areas that cannot be reached with a straight nozzle.
The compact design uses a 7.1 mm nozzle and requires a correspondingly powerful compressed air supply. The nozzle holder is not included with this item and must be added to match the existing system.
✅ For small pipe internal diameters of 19–50 mm
✅ All-round processing of the internal pipe wall
✅ Compact design for confined lines
✅ Surface preparation up to Sa 2½ possible
✅ For common suitable abrasives
✅ Professional Clemco system component

System design
The blast hose and all upstream fittings must provide the required flow rate with as little pressure loss as possible. Use only dry, clean abrasive with the maximum suitable grit size. Moisture or excessively coarse grit may block the short blast path.
Typical applications
✔ Internal cleaning of small pipes and lines
✔ Rust and scale removal
✔ Preparation before coating or lining
✔ Plant, pipeline, and maintenance work
Maintenance and safety
Regularly check the deflector head, nozzle, and plug-in/connection area for wear. Only install the unit and remove it from the pipe when depressurized. Pipe ends must be secured, as abrasive and loosened particles may be ejected at high speed.
FAQ – frequently asked questions
Is a nozzle holder included?
No, the appropriate nozzle holder must be selected separately to match the existing system.
What grit size is permitted?
As a guideline, approximately 0.4 mm maximum.
How much compressed air is required?
At 9 bar, approximately 3.0 m³/min plus a reserve for line losses.
