T95 Casing Tubing - API Certified Mill Direct Supplier | Kuaima Steel Group

T95 casing tubing is a high-strength, heat-resistant steel grade engineered for demanding oil and gas well completions where both mechanical performance and sulfide stress cracking (SSC) resistance are critical. As an API 5CT certified mill-direct supplier, Kuaima Steel Group delivers premium-grade T95 casing and tubing products to operators and distributors worldwide. Our T95 OCTG products undergo rigorous quality control — from raw material selection through final inspection — ensuring every joint meets the stringent requirements of deep well and sour service environments. Whether you're sourcing for high-pressure gas wells, offshore platforms, or geothermal projects, our extensive inventory and flexible production capability allow us to fulfill orders with competitive lead times and cost-effective mill-direct pricing.

What Is T95 Casing Tubing?

T95 casing tubing is a controlled-yield-strength steel grade defined under API Specification 5CT (ISO 11960). The "T" designation indicates the grade has been specifically heat-treated — quenched and tempered — to achieve a restricted yield strength range while maintaining superior resistance to sulfide stress corrosion cracking. T95 serves critical roles in well construction as both casing (structural lining of the wellbore) and tubing (the production conduit), particularly in environments containing hydrogen sulfide (H₂S). It bridges the performance gap between standard L80 and higher-strength Q125 grades, offering operators an optimal balance of strength, toughness, and sour service reliability.

T95 Casing Tubing Technical Specifications

All T95 casing and tubing products supplied by Kuaima Steel Group conform to the latest edition of API 5CT / ISO 11960. Below are the key mechanical and dimensional parameters:

Property	Specification
Grade	T95 (API 5CT / ISO 11960)
Minimum Yield Strength	655 MPa (95 ksi)
Maximum Yield Strength	758 MPa (110 ksi)
Minimum Tensile Strength	724 MPa (105 ksi)
Minimum Elongation	Per API 5CT formula (varies by wall thickness)
Hardness Requirement	≤ 25.4 HRC (SSC compliance)
Heat Treatment	Quenched & Tempered (Q&T)
Casing OD Range	4-1/2″ to 20″ (114.3 mm – 508.0 mm)
Tubing OD Range	1.050″ to 4-1/2″ (26.67 mm – 114.3 mm)
Wall Thickness	Per API 5CT dimensional tables
Length Range	R1 (16–25 ft), R2 (25–34 ft), R3 (34–48 ft)
Connection Types	STC, LTC, BTC, Premium (VAM, Tenaris Blue, etc.)
Sour Service	Compliant with NACE MR0175 / ISO 15156
Testing	Full-length hydrostatic test, NDE (UT/EMI), Charpy impact at 0°C

Each T95 casing tubing joint undergoes full-body ultrasonic inspection, electromagnetic inspection, and hydrostatic pressure testing to ensure zero-defect delivery. Charpy V-notch impact testing at 0°C verifies fracture toughness, while hardness mapping across the cross-section confirms NACE MR0175 compliance for sour gas service.

Key Applications of T95 Casing Tubing

T95 casing tubing finds extensive application across the most challenging segments of the energy industry:

Sour gas wells: H₂S-bearing formations requiring NACE-compliant materials with controlled hardness and SSC resistance.
Deep and ultra-deep wells: High-pressure, high-temperature (HPHT) environments demanding yield strengths above L80 while maintaining ductility.
Offshore drilling: Subsea completions where reliability and corrosion resistance are non-negotiable.
Geothermal energy: High-temperature wells with aggressive downhole chemistry.
CO₂ injection wells: Carbon capture and storage (CCS) projects requiring combined strength and corrosion performance.

Frequently Asked Questions

What is the MOQ for T95 casing tubing?

Our minimum order quantity is typically 20 metric tons for standard sizes. For non-standard OD or wall thickness combinations, MOQ may increase to one heat lot (approximately 40–60 tons) depending on mill scheduling.

Do you provide material test certificates?

Yes. Every shipment includes EN 10204 Type 3.1 Mill Test Certificates covering chemical composition, mechanical properties (yield, tensile, elongation, hardness, Charpy impact), hydrostatic test results, and NDE reports. Third-party certificates from SGS or Bureau Veritas are available upon request.

Quality Fine — Coupling Issue Resolved Promptly
Ordered 30 tons of T95 tubing, 4-1/2" OD with BTC connections for a Marcellus Shale well. Pipe body quality was excellent — clean UT, proper Q&T heat treatment, hardness under 25 HRC. However, about 5% of couplings had minor thread damage likely from handling during transit. We reported it and Kuaima shipped replacement couplings within two weeks at no charge, plus added extra protective thread caps for the full order. Issue resolved satisfactorily. The pipe itself performed well downhole. Fair to say they stand behind their product.

Solid T95 Product at Competitive Rates
We procured T95 casing 5-1/2" OD LTC, approximately 45 tons, for an ONGC contractor project requiring NACE MR0175 compliance. The material met all API 5CT specifications — yield, tensile, hardness, and Charpy impact values were within range. Pricing was very competitive for Indian market conditions. Delivery took 38 days for this custom wall thickness, slightly beyond the initial 30-day estimate, but still within our project timeline. Would rate higher if lead time had been exact. Planning a larger order next quarter.

Good Value T95 Casing — Minor Documentation Delay
Ordered 60 tons of T95 casing, 7-5/8" OD BTC for a development well. Product quality was solid — all API 5CT mechanical requirements met, UT inspection clean, hydrostatic test passed. Mill-direct pricing was noticeably better than European stockholders. The only issue was the final MTR package arrived about 4 days after the physical shipment, which caused a brief hold at our yard. Kuaima acknowledged this and has since committed to shipping documents in advance. Overall good value for the price.

Repeat Order — Consistent Quality Across Batches
This is our third order of T95 tubing, 2-7/8" OD with STC connections, for H₂S-bearing wells in the Cooper Basin. What keeps us coming back is the batch-to-batch consistency — hardness always within NACE MR0175 limits, tensile properties tight within the 95-110 ksi yield window. SGS inspection at the mill confirmed everything before shipping. Kuaima also accommodated our request for custom R2 lengths cut to 28 ft. Logistics to Melbourne were well-coordinated. Solid long-term supplier.

Competitive Mill-Direct Pricing with Fast Turnaround
As a regional OCTG distributor, we restocked T95 casing in 7" and 9-5/8" OD, both LTC and BTC threads, totaling 200 tons. Kuaima's mill-direct pricing saved us roughly 8-10% compared to our previous trading company source. Standard sizes shipped from stock within 10 days to Jebel Ali. API monogram verified, full documentation package included. Our end-users in Oman and Kuwait have had zero complaints on quality. We've now set up a quarterly replenishment schedule with Kuaima.

Strong Technical Support for Geothermal Application
We specified T95 casing 13-3/8" OD for a deep geothermal well in Bavaria with aggressive downhole chemistry. Kuaima's OCTG specialists helped us select the right wall thickness and connection type based on our collapse and burst pressure calculations. All mechanical properties — 95 ksi minimum yield, Charpy impact at 0°C — were confirmed on the mill test certificates. Hydrostatic test pressures exceeded our requirements. Shipment of 80 tons arrived in Hamburg within the quoted 35-day window. Very professional.

Reliable Supply for Offshore Platform Recompletion
Sourced T95 tubing in 3-1/2" OD, R3 lengths with VAM premium connections for an offshore recompletion project. Gas-tight seal performance was critical at our downhole pressures. Kuaima's team provided detailed threading inspection reports and full-body UT/EMI certificates per API 5CT. The 42-day lead time for premium-threaded custom orders was met exactly. Material traceability from heat number to final coupling was impeccable. Will definitely consider them for our upcoming North Sea HPHT campaign.

Excellent T95 Casing for Our Sour Gas Wells
We ordered 120 metric tons of T95 casing, 9-5/8" OD with BTC connections for sour gas completions in West Texas. Every joint came with full EN 10204 Type 3.1 MTR — yield strength, hardness mapping, and Charpy impact results all verified against NACE MR0175. Our third-party inspector from Bureau Veritas confirmed zero rejects across the entire shipment. Hardness readings consistently under 25 HRC. Kuaima delivered ex-works in 12 days from stocked inventory. This is our second order and we've already placed a third for 7" tubing.
