API标准油井管——规格、钢级与尺寸

API标准石油井管是现代石油开采的支柱,其设计能够承受钻井和生产作业中遇到的极端井下压力、腐蚀性环境和高温条件。这些管材产品严格按照美国石油学会规范制造,是寻求可靠井筒完整性的油气运营商的首选。无论您需要套管、油管还是钻杆,我们的钢厂直供确保为全球上游能源项目提供质量稳定且完全可追溯的产品。

什么是API标准石油井管?

API标准石油井管是指按照API规范5CT(套管和油管)和API规范5D(钻杆)制造的无缝或焊接钢管产品。这些管材专为衬砌井筒、从地下储层输送碳氢化合物以及在钻井作业中提供结构支撑而设计。每根管材都经过静水压试验、无损检测和尺寸验证,以确保在严苛的油田条件下性能可靠。

API 石油井管主要钢级

J55 和 K55 套管

J55 和 K55 属于入门级碳钢钢级,最小屈服强度分别为 379 MPa,最大为 552 MPa。这些钢级广泛应用于地层压力适中的表层套管和中间套管串中。其经济实惠的价格使其成为浅井至中深井建设的理想选择。

N80 和 L80 油管和套管

N80 的最小屈服强度为 552 MPa,适用于较深井的中间套管和生产套管。L80 的硬度受控,不超过 API 5CT 第 7.8 节规定的 23 HRC,常用于含硫化氢 (H₂S) 分压高于 0.05 psi 的酸性服役环境,符合 NACE MR0175/ISO 15156 要求。

P110 高强度套管

P110 钢级石油井管具有卓越的机械强度,最小屈服强度为 758 MPa,专为深井和高压油藏应用而设计。该钢级经常被选用于深度超过 12,000 英尺的生产套管串,在这些应用中,抗挤毁和抗爆破性能至关重要。

常见问题解答

最小起订量(MOQ)是多少?

我们API油井管的标准最小起订量为每个钢级和尺寸组合20公吨。根据当前钢厂库存情况,可应要求接受较小的试订单。

你们提供材质检测证书吗?

是的,每批货物均附有EN 10204 Type 3.1钢厂检测证书,记录化学成分、力学性能、静水压试验结果及无损检测记录,完全符合API 5CT要求。

典型的交货时间是多久?

现货商品在7–15个工作日内发货。涉及特定钢级、优质接头或非标准长度的定制订单,通常需要自订单确认起30–45天达到出厂状态。

你们能供应带优质螺纹接头的管材吗?

当然可以。除标准STC、LTC和BTC螺纹外,我们还提供优质气密接头,专为高压、高温及定向井应用中增强密封性能而设计。

Acceptable Quality — Packaging Issue Resolved
Ordered 20 tons of J55 casing 7" OD with STC connections. Pipe quality and API 5CT certificates were fine, but some bundles had damaged wooden cradles on arrival at Santos port, causing minor surface scratches on 4 joints. Supplier agreed to a small credit and improved packaging for our next order. Material itself met specs.

Reliable L80 Tubing Supply for Southeast Asia Client
Sourced 45 tons of L80 tubing 3-1/2" OD with premium connections for our end client's sour gas well in Myanmar. Pricing was competitive after negotiation on a 2-shipment commitment. NACE compliance documentation was thorough. Delivery took 38 days for the custom premium connection, which was within the quoted window. Would prefer slightly faster lead time on non-stock items, but overall a dependable supplier.

Good Value P110 Casing for Cooper Basin Project
Compared quotes from 4 suppliers for 50 tons of P110 casing, 5-1/2" OD with BTC threads. This supplier was about 8% lower than the nearest competitor while maintaining API monogram certification. Material quality was solid — no rejects after our third-party inspection. Only minor point: some thread protectors were slightly loose during transit, but no thread damage found.

Perfect Repeat Order — K55 and N80 Mixed Shipment
Third order in 14 months. This time 25 tons K55 surface casing 9-5/8" and 35 tons N80 intermediate casing 7" OD, both with LTC connections in R2 lengths. Quality has been consistent across all three shipments. Drift testing passed on every joint at our pipe yard inspection. Our procurement team now treats this supplier as our primary source for API 5CT products.

Premium Service on Urgent J55 Surface Casing Order
Needed 30 tons of J55 surface casing, 13-3/8" OD with STC connections urgently for a rig waiting in Abu Dhabi. Sales team confirmed stock availability within 6 hours and arranged shipping in 9 days. Varnish coating and thread protectors were in good condition on arrival. All documentation including hydrostatic test results was emailed before cargo reached port. Responsive and professional throughout.

Outstanding N80 Casing Delivered Ahead of Schedule
Ordered 60 tons of N80 casing pipe, 7" OD × 8.05 mm wall with LTC threads for an intermediate casing string in our Libya project. Chemical composition and mechanical properties on the EN 10204 Type 3.1 certificates matched API 5CT specifications precisely. Yield came in at 574 MPa. Shipment was ready 11 days after confirmation, giving us a 4-day buffer before our vessel loading date.

Excellent L80 Tubing for Sour Service Application
We required 40 tons of L80 tubing, 2-7/8" OD with premium gas-tight connections for an H₂S-bearing reservoir in the North Sea. Hardness results on the 3.1 certificates showed 21 HRC max, fully compliant with NACE MR0175. Phosphate coating was uniform with no bare spots. Delivery took 18 days from order confirmation to our Aberdeen yard. Technical team responded to our connection queries within hours.

Superior P110 Casing for Deep Well Program
Purchased 85 tons of P110 casing, 9-5/8" OD with BTC connections for our 14,000 ft production wells in the Permian Basin. Mill test certificates confirmed yield strength at 793 MPa, well within API 5CT PSL-2 requirements. Wall thickness measured consistently at 11.99 mm against the 11.99 mm nominal. Hydrostatic test records and full NDE documentation included. Pipe arrived in R3 lengths as requested. Second order this year.
