The drill pipes are manufactured in our company from two components. The sockets and pins are made of quenched and tempered steel and can be surface-hardened on request. The pipe itself is made of structural steel and has a wall thickness of 10 mm as standard. The components are joined using the friction welding process in our friction welding facility and has proven to be highly resilient in practice.
The drill pipes are available in various lengths and diameters. Standard lengths:
By the help of the flushing head, which is made of different components, the flushing medium – air or water – is lead into the drill string. This will ensure that the drilling cuttings are delivered through the annular gap up to the surface. By using a one-way flushing, another positive effect is the prevention of the penetration of sand and clay into the drill string.
The flushing heads are made of tempered steel, surface hardened. The technical drawing shows an example of it. We do offer a variety of flushing heads and we’ll be glad to provide any consulting regarding the specific requirements of your local conditions.
The lost bit is made of grey cast iron and is therefore cost-effective and highly resilient. It is mainly used for core drilling in very deep areas. The drill bit does not overheat in the process.
Zipp Industries GmbH & Co. KG has made good experiences with the diameters 88.9-152.4 mm from years of knowledge. The specified versions are available in left-hand and right-hand form. Versions:
Lost bit with cross cutting edge
wide carrier - with or without flushing connection
Lost bit with bayonet lock
available with cross-type cutting or spade edge
The driving shoe has the function to pick up the lost bit and to save the drill rods. The locking mechanism of the lost bit depends on the impact device used and on the fact, whether the customer intends to reuse the drill bit or not.
