Product Types We Manufacture
We don’t just make one "standard” coiled tubing. Our product portfolio is built for real operational diversity.
-
Standard Carbon Steel CT (CT70–CT90) – Best for routine well intervention, cleanouts, and light workover. Economical and reliable.
-
High-Strength CT (CT100–CT110) – Designed for deep wells, high differential pressure, and extended-reach drilling. Higher tensile strength allows smaller OD strings to reach deeper.
-
Low-Temperature CT – Special chemistry and heat treatment for arctic and cold-climate use. Proven at -45°C in Siberian fields.
-
Corrosion-Resistant Alloy (CRA) CT – Available on demand for H₂S / CO₂ sour service. Please share your fluid composition for a material recommendation.
-
Tapered Coiled Tubing Strings – Optimized weight distribution – thicker wall at the bottom for strength, thinner wall up top for lighter weight and longer reach.
Where Our Coiled Tubing Is Used
Our coiled tubing manufacturers' expertise serves these applications globally:
-
Well intervention (sand cleanout, acidizing, milling, fishing)
-
Velocity string installation (gas well deliquification)
-
Underbalanced drilling & thru-tubing rotary drilling
-
Logging & perforating with CT-conveyed tools
-
Cementing & plug setting
-
Paraffin & scale removal in mature fields

Frequently Asked Questions (FAQ)
Q1: Are you an actual coiled tubing manufacturer or a trading company?
A: We are a direct manufacturer – a wholly-owned subsidiary of Sinopec Oilfield Equipment Corporation. Our factory has been producing coiled tubing since 2004. You’re welcome to request a virtual factory tour or video call with our production team.
Q2: What certifications do you hold?
A: API 5ST, API Q1, ISO 9001:2015, ISO 14001, and ISO 45001. API monogram available upon request for applicable sizes/grades.
Q3: What is the minimum order quantity (MOQ) for custom coiled tubing?
A: Typically one full reel (approximately 5,000–7,500 meters depending on OD). For smaller trial orders, please contact us – we can sometimes accommodate.
Q4: Can you provide tapered coiled tubing strings?
A: Yes. Tapered CT strings (varying wall thickness along length) are a standard offering. We’ll design the taper profile based on your well’s dogleg severity, depth, and required working pressures.
Q5: How long does delivery take?
A: Standard CT strings: 30–45 days after order confirmation. Custom grades or large quantities: 50–60 days. Expedited options are possible – just ask.
Q6: Do you offer after-sales technical support?
A: Absolutely. We provide:
-
Pre-sale job planning and string selection advice
-
Fatigue life modeling
-
On-site commissioning assistance (optional)
-
Operator training (remote or on-site)
Q7: Can you supply coiled tubing for sour gas wells (H₂S)?
A: Yes – for sour service we recommend our corrosion-resistant alloy (CRA) coiled tubing or specially heat-treated low-alloy steel. Please share your H₂S/CO₂ partial pressures and we will advise.
Q8: What payment terms do you accept?
A: Typically T/T (30% deposit, 70% before shipment) or LC at sight for international customers. Negotiable for long-term partners.
