At its core, submarine hammer drilling employs a powerful hammer mechanism to drive a drill bit into the seabed. The system utilizes both air and water pressure to deliver repeated impacts on the drill bit, which enables it to break through hard rock formations or sediments that might hinder installation efforts for marine infrastructure. The design of the hammer ensures that the energy is efficiently transmitted to the drill bit, allowing it to operate at significant depths.

  • Furthermore, fire seal tape is highly versatile and can be used in a variety of applicationsfirefire seal tape. It can be applied around electrical outlets, piping, and HVAC ducts to prevent the spread of fire through these vulnerable areas. It can also be used to seal gaps around doors and windows, helping to create a barrier against fire and smoke intrusion.

  • Furthermore, self-bonding rubber tape is often used in hobbies and craft projects. Artists and DIY enthusiasts appreciate its flexibility and the variety of color options available, allowing them to create unique designs while enjoying the same reliability offered in more practical applications.


  • Are there different types of control boxes? Pump control boxes can really be separated into three (3) different types, Quick Disconnect (QD), Standard, and Deluxe. The QD boxes are designed for smaller horsepower motors and generally include 1/2hp, 3/4hp, and 1hp applications. Standard control boxes cover 1hp-10hp while Deluxe boxes cover 2hp-15hp. The Deluxe boxes have the addition of a line contactor which allow for an alternate wiring configuration of the pressure switch. Check out our videos on pressure switches and control boxes for more information on this topic. Another notable difference between the QD box and the Standard/Deluxe boxes are the presence of overload protection in the Standard/Deluxe boxes.

  • Follow up this first step by wrapping four half-lapped layers of rubber insulating tape over the cambric tape, which creates a moisture barrier and provides the primary insulation in the connection. Finally, over-wrap the assembly with a minimum of two half-lapped layers of vinyl electrical tape. This should extend approximately two tape widths beyond the ends of the rubber tape. Stretch this tape as you wrap it so you get good conformance to the underlying structure. This also helps complete the moisture seal.

  • In retail environments, floor marking tape is invaluable for crowd control and social distancing measures, especially in the current global health crisis. It helps maintain queues, defines one-way systems, and promotes safe distances between customers, contributing to a secure shopping experience.

  • Electrical wiring and phasing tasks call for a specific type of tape – electrical tape – in order to safely get the job done. But what exactly is it that makes electrical tapes so different from duct tapes, polyethylene film tapes, and others?

  • Applications


  • Whether you’re an electrician or are just working on a job site, it’s important to know the differences between different types of tape. Electrical tape is best suited for electrical insulation and securing electrical connections, ensuring safety when dealing with electrical components. On the other hand, duct tape thrives in its versatility and strength, making it an excellent choice for general repairs. As always, we recommend testing tape before use, and adhering to all manufacturer guidelines. Explore Surface Shield’s full line of tape options.
