Types of Casing Tube
The casing tube produced by our company mainly include the following types:
NW HW PW Drill Casing Pipe 4130 1541 30CrMo 40Mn2 N80 R780 J55
Seamless casing pipe is used to prevent borehole collapsing, which are widely used in geotechnical applications. Even though casing tube is not subject to the same stresses as drill rod, we apply the same care in design, manufacturing and quality assurance disciplines for all our tubular products.
Dingxin’s seamless casing pipes are designed and produced according to industry standards as GB/T 9808, ISO 10097, DCDMA, etc., designations. We offer a range of alloy steel raw material with different heat treatments to meet customers’ diversified requirements in cost and application.
N80 J55 K55 Casing Pipe
Casing pipes are what are place in the hole once the drill if finished. This keeps the shape for the hole and offers a framework to work with. This strengthens the hole that was just drilled and takes away the hazard of the hole collapsing and effecting a cave in. The tubes are mainly alloy steel tube to withstand a lot of inner earth pressure.
N80 casing pipe, J55 casing pipe, K55 casing pipe are general grade tubing that widely used in oil and gas drilling activities. As we know Grade J55/K55 is the low grade in API 5CT specification for casing and tubing. A higher grade than J55/K55 is N80, it is a medium grade divides in N80-1 and N80-Q.
Benefits of Casing Tube
Corrosion Protection
One of the primary advantages of using casing tubes is their ability to safeguard the enclosed pipes from corrosion. By preventing direct exposure to corrosive substances in soil and groundwater, casing tubes substantially mitigate the risk of pipe degradation over time. This corrosion resistance is essential for preserving water quality and ensuring the long-term reliability of plumbing systems.
Structural Reinforcement
Casing tubes offer additional structural support to underground pipelines. They effectively distribute external loads and pressures, thereby reducing the likelihood of pipe collapse or deformation caused by soil movement or heavy traffic loads. This reinforcement is particularly critical in areas with unstable soil conditions or where pipelines are vulnerable to external damage.
Ease of Maintenance
The installation of casing tubes enhances accessibility for maintenance and repair operations. When maintenance is required, technicians can access the enclosed pipes with minimal excavation, thereby minimizing disruption to the surrounding environment and reducing repair costs. This improved accessibility benefits both residential and commercial plumbing systems, where minimizing downtime and operational disruptions is paramount.
