TIPS TO CONSIDER WHEN PURCHASING CLOSURES
When selecting Closures, pipeline operators should consider safety and performance factors. The TDW D2000 Closures with the ProSeries™ Advantage is the safest, most trusted closure on the market.
“Imitation is the sincerest form of flattery that mediocrity can pay to greatness.”
Don’t compromise safety and performance by settling for imitations. When it comes to closures, cutting corners isn’t an option. The safety of your crews, the integrity of your pipeline, and the efficiency of your operation all hinge on choosing the right product.
TDW’s D2000 ProSeries closures are backed by more than 100 years of engineering expertise, field experience, and continuous innovation.
When you invest in the D2000 ProSeries, you’re not just buying a closure—you’re choosing the best-in-class solution backed by a manufacturer who will be here for the lifetime of your pipeline.
the manufacturer
Proven track record – Does the manufacturer have decades of field-proven reliability, or are they new to the market? TDW closures have been rigorously tested and trusted by operators worldwide for generations.
Life cycle support – A closure is only as good as its support. Look at availability of parts, repair services, and consumables like O-rings and Pressure Warning Locks (PWLs). TDW ensures long-term support for every component.

SAFETY FIRST
The primary question: Does the design keep the operator out of the danger zone?
Operator positioning – With the D2000, operators can safely open the closure from outside the direct line of danger.
Pressure Warning Locks – Placement matters. PWLs located in the 12 o’clock position are less likely to collect debris than those on the door face. The D2000 design directs any retained pressure safely away from the operator.
Durability and spares – Unlike metal-to-metal seals that wear out quickly, TDW’s PWLs are supported with readily available O-rings and replacement parts, ensuring reliability and uptime.
Design AND FEATURES that matter
Simplicity of operation – Fewer moving parts mean fewer failure points and easier maintenance.
Ease of alignment – A single pivot point makes aligning the door with the collar straightforward and efficient.
Clamping surface design – Closures with parallel, non-wedging clamp-rings eliminate force transfer to holding components, reducing wear compared to tapered, wedging surfaces.
O-Ring LOCATION and performance
Sealing performance is critical, and O-ring placement makes a big difference.
Protected placement – O-rings positioned on the external outer edge of the collar are less likely to be damaged during pig loading or removal, and they’re better protected from debris.
Leak prevention – Properly compressed O-rings perform even at low pressure, reducing leak risks.
Material options – TDW offers multiple O-ring materials to suit varying operating conditions, giving operators flexibility and reliability.
TDW closures are there for the lifetime of your pipeline.

FLAMMABLE AND TOXIC INDUSTRIAL GAS DETECTORS
September 2025 - Pittsburgh, PA
Kerr Engineered Sales Company announces new partnership with Teledyne. Unlike portable detectors, fixed detection devices make it possible to secure an entire area 24 hours a day. They can also be connected to a detection system, which displays the gas concentration in numerical value, and then triggers the servo-controls in the event of an abnormal value.
Detect abnormal or dangerous presence of gas in a specific area and warn users in the event of potential hazards. Some models are equipped with sensors that can measure the concentration of one or more types of gas.
TELEDYNE Products are stocked by United Products, KERR Engineered Sales distribution partner.
