Perimeter Intrusion Prevention

The API composite thread protector is made of a threaded low density or high-density polyethylene bumper, which absorbs the impact shocks and a steel shell rolled over the front edge, which insures a superior protection against hazard. The composite thread protector is available either in the open end or closed end version, liftable or non-liftable. The liftable protectors allow moving of the tubes using hooking devices and in the same time keep the tube thread and coating undamaged. The closed end protectors may have an optional vent hole designed to keep the inner pressure equal to the outer pressure. The vent hole may also have a filter, which prevents the intrusion of the foreign particles. The composite design of the composite thread protector (steel shell and high density polyethylene bumper) insures the protector integrity within the temperature range given by the API 5CT standard (-46 C ·66 C). Their design allows easy setting and removing using a tube wrench. CASING/TUBING/DRILL PIPE/DRILL COLLAR THREAD PROTECTOR 1) Material: steel/plastic/steel&plastic 2) Size: 2 3/8"--- 20" 3) Thread type: STC, LTC, BTC and other thread according with customized

china coal 0001 Arc Plate Net Shell Support Keywords: Net Shell Support, Stainless Steel Support, Steel Supports Price Introduction of Arc Plate Net Shell Support Supporting of soft rock tunnel excavation has been one of the key technical problems which affects the further development of coal industry production and construction of our country . Deep mine ground pressure intensity is high, under the condition of mining influence and impact ground pressure and strata control is especially difficult, thus support system is more and more strengthened, such as the need to reduce the frame from u-shape set, strengthen the link rod, and even to use U36 steel;spray the anchor net supporting to reinforced by steel arch, or and anchor rope combined support, surrounding rock grouting, etc; Although this can achieve certain supporting effect, but support cost is very high. Therefore, China coal group design to create a new type of flat net shell components, the main supporting characteristics of arc plate net shell components summed up as: "while digging, while supported edge, "before soft to hard", enough stiffness, process simple,low price." Characteristics of Arc Plate Net Shell Support 1,"While digging, while supported edge",timely support Arc Plate Net Shell Support can use waste rock filling, grey package after wall, concrete precast slab, such as filling, network frame and the tunnel contour quickly close to stick, while digging, timely support, so that on the one hand can make the support resistance of support was able to play in time, to timely reinforce the surrounding rock and to work under the stress state in three; On the other hand, have the effect of slow pressure, pressure, lead to the uniform support along the perimeter stress, is in good working condition. 2,Arc Plate Net Shell Support has enough "rigidity" 3,"Just moderately soft, before soft to hard". Arc Plate Net Shell Support force has a complex ingredients: expansion and creep of rock mass, reduce the strength of long, crushing of rock mass adhesion coefficient reduced values, etc., all show the macroscopic displacement of rock mass and any rigid support to prevent displacement will be entirely itself in disadvantage. Therefore, the stability of the laneway to end support, work together to complete of the surrounding rock. Reticulated shell scaffold, while under high in-situ stress reaction in surrounding rock, making convergence of surrounding rock in supporting under the control of convergence, by stent supported edge, the edge of broken rock mass convergence pressure unceasingly, forming a stable bearing ring, together with stents to assume the role of in-situ stress. The scalability of Arc Plate Net Shell Support comes from two aspects: (1) the contact of the spatial grid steel supports and surrounding rock itself has certain yielding; (2) the junctions between the reticulated shell scaffold piece and piece of wood plate.

Key Principles of an Effective Perimeter Security Program Deterrence: Fortifications are the best deterrent to attackers. Often, perimeter fencing/barriers and other visible mechanisms such as Perimeter Intrusion Detection Systems (PIDS), lighting, and cameras serve as deterrents to potential attackers. Detection: The implementation of detection sensors enhances the ability to identify intruders and avoid attacks. It is recommended that at least a single layer of PIDS technology be introduced to detect intruders at the perimeter. Often, a two-layer approach is required to protect facilities with higher security requirements (i.e., potential theft or damage to higher value assets). Layered complementary technologies, such as fence sensors and video analytics, can reinforce the perimeter layer. For the highest security applications (i.e., where there is a threat to critical infrastructure or human life), multi-layered systems utilizing a range of technologies further increase the level of protection. Latency: Maximizing the time span from entry to attackable assets is critical so that security teams have time to respond. Physical barriers at the perimeter, PIDS on and inside the perimeter fence, internal barriers (ideally with PIDS), and the distance between the barrier and the attackable asset are all delay mechanisms that slow down the attacker. Assessment: introduce an integrated system that includes alarm communications and CCTV/video intrusion assessment. Operators need to see what the system detects. Response: Design scenarios and deploy response forces to stop threats/attacks or intruders.
