Range of Sizes for Wellhead Christmas Tree

Range of Sizes: 2 1/16” to 5 1/8”

Applications of the Wellhead Christmas Tree

For Oil and Gas exploration. Wellhead and Christmas Tree composed by three parts, including casing head, tubing head, oil (gas) tree, used to connect casing string, tubing string and sealing layers between the casing and tubing of the annular space between, so to control the wellhead pressure and wellhead flow, it also could be used for acid fracturing, water injection, testing and other special operations.

Types of Processes for Oil and Gas Wellhead

The Oilfield oil and gas Wellhead, Christmas tree is an assembly of valves, spools and fittings for an oil well, and to design to direct and control formation fluids from the well. It can provide inlet for production tubing strings, including all components above the tubing head adapter. Wellhead Christmas tree assemblies can constitute many different kinds of combinations in order to meet any special requirement. Based on their different functions, Wellhead Christmas tree can be classified into such special Wellhead Christmas tree as oil production (flowing and artificial lift) Wellhead Christmas tree, gas (natural gas and various sour gas) production Wellhead Christmas tree, water injection Christmas trees, thermal recovery Christmas trees, fracturing Wellhead Christmas trees and acidizing Christmas trees. Different pressure ratings serialize Wellhead Christmas trees.

The gas production Wellhead Christmas tree and tubing head are mainly used to produce gas and inject gas. The relative density of natural gas is low and gas column pressure is low, while well head pressure is high and liable to leakage regardless of gas production and gas injection. Sometimes natural gas contains corrosive media such as H2S and CO2. Therefore, the gas production Christmas tree calls for rigid requirements on both its materials and its sealing characteristics. For the sake of safety, two gate valves are used on the tubing and casing respectively. Some gate valves to be used on high pressure and ultra-high pressure gas wells are integrated valves manufactured from high quality forged steel.

API SPEC 6A

Octal Steel provides complete, integrated production lines for LSAW, SSAW, ERW, seamless pipe and anti-corrosion coating. All sections — from plate/coil preparation, forming and welding to NDT, beveling and 3LPE/FBE coating — are designed to work together as one system, not as separate islands of equipment.

When you invest in a steel pipe plant, you are not just buying machines — you are buying production capacity, product quality and delivery reliability for the next 10–20 years.A poorly designed line means bottlenecks, unstable quality and constant troubleshooting. A well-matched line runs smoothly, produces pipes that pass inspection, and helps you win projects.

On top of the mechanical line, we integrate modern intelligent control systems widely used in leading Chinese mills:
Production parameters, welding currents, temperatures, line speeds and NDT results are captured and updated in real time. This kind of digital control and data logging gives you:

1. More stable and repeatable product quality
2. Full production and QA traceability for every pipe
3. Faster troubleshooting when something goes wrong
4. Clearer KPI and efficiency monitoring for plant management

For the buyer, this means one responsible supplier for both the production line and its digital backbone, with processes already matched to API / ASTM / EN / GB standards, and a plant that is easier to start up, manage and maintain.

LSAW (JCOE) Pipe Production Line

For large-diameter, high-grade line pipe and structural pipe, we offer full JCOE LSAW pipe lines, including:

This line is suitable for producing API 5L / ISO 3183 / GB/T 9711 pipes for long-distance oil, gas and water transmission, as well as heavy structural and piling applications.

SSAW (Spiral Welded) Pipe Line

For high-efficiency production of long-length spiral pipes, we supply:

ERW (High-Frequency) Pipe Line

For small and medium diameters, we provide high-frequency ERW straight-seam pipe mills, including:

This line covers ASTM A53, API 5L, EN 10219, water and gas pipes, structural hollow sections and other low/medium-pressure applications.

Seamless Pipe Line (Hot Rolling & Finishing)

For seamless pipe projects, we can design and supply the key equipment for:

The seamless line is suitable for boiler tubes, OCTG, high-pressure pipe and high-temperature alloy pipe production.

Anti-Corrosion Coating & Lining Lines

To complete the production chain, Octal Steel also supplies external and internal coating lines matched to the pipe mills:

3LPE Coating Production Line (External Pipe Anti-Corrosion System)

A 3LPE coating production line is designed to apply a three-layer polyethylene system—Fusion Bonded Epoxy (FBE) primer, copolymer adhesive, and outer PE jacket—to steel pipes for long-term corrosion protection in buried and submerged pipeline service. In Octal’s configuration, the 3LPE coating line is integrated with upstream pipe mills to keep surface condition, temperature control, and line speed consistent, which is critical for coating adhesion and thickness uniformity.

The process starts with closed-cycle shot blasting to achieve SA 2.5 surface cleanliness, followed by induction pre-heating to maintain the steel surface at a controlled temperature window suitable for FBE bonding. The FBE layer is applied by electrostatic powder spray guns or a fluidized bed system, typically producing a uniform epoxy layer in the 350–600 μm range in accordance with ISO 21809 and NACE requirements.

After FBE gelation, the pipe enters the adhesive and PE extrusion section, where a copolymer adhesive layer and PE topcoat are applied through an extruder and T-die system. Total coating thickness is commonly controlled within 2.5–4.5 mm for standard 3LPE systems, with peel adhesion values typically exceeding 250 N/cm at 23 °C, depending on project specification. A closed-loop water quenching and air cooling tunnel stabilizes the PE layer without inducing crystallization damage or residual stress.

Quality control on the 3LPE coating production line is carried out inline. Each pipe undergoes 100% holiday detection using an adjustable DC high-voltage detector (up to 25 kV) to verify pinhole-free coating integrity, followed by thickness measurement, adhesion testing, and visual inspection. Where required, the same line can be configured for internal epoxy or FBE lining, allowing combined external corrosion protection and internal flow-efficiency solutions.

By supplying the 3LPE coating production line as part of a complete pipe manufacturing and finishing package, Octal Steel enables consistent coating performance, traceable inspection records, and coating systems that are ready for pipeline installation without secondary handling or rework.

Why Work with Octal Steel for Complete Lines

• One package from steel pipe to coating – LSAW, SSAW, ERW, seamless and coating lines designed to work together instead of being pieced together from different suppliers.

• Process + equipment – We provide not only machines, but also process layouts, equipment selection, utilities list and basic process parameters based on API/ASTM/EN standards.

• Installation and commissioning support – Supervising installation, start-up, trial production and training for operators and maintenance staff.

• Experience from real pipe mills – Our solutions are based on mills already running for line pipe, OCTG, piling and coated pipe projects in the Middle East, Asia, Europe and South America.

• Smart & Digital Steel Pipe Manufacturing Base

  Modern pipe mills are moving from simple automation to truly digital and intelligent manufacturing. Octal Steel can help you build not just a production line, but a smart steel pipe manufacturing base with a million-tonne class operation system behind it.

  Instead of isolated machines, the whole plant is connected through an integrated MES / SCADA platform:

  • Real-time data from every key station – forming, welding, heat treatment, NDT, hydrotest and coating all feed live data into one system. Production speed, welding current, temperatures and coating thickness are monitored and adjusted on the fly.

  • Full-process digital traceability – each pipe carries its own digital record: heat number, forming parameters, NDT results, hydrotest pressure, coating data. This supports API / ASTM / EN / GB standards and makes third-party audits much easier.

  • Smart production planning and scheduling – the system can balance orders, grades and sizes across the line, helping you run a competitive million-tonne operation with fewer bottlenecks and higher line efficiency.

  • Data-driven quality and R&D – quality trends and process data are stored and analyzed, so your technical team can optimize welding procedures, coating recipes and heat-treatment curves instead of relying only on experience.

  For investors and plant owners, this means the new mill is not just “automated” on paper, but truly upgrades your digital manufacturing capability and technical level. You get a plant that can produce competitive steel pipe at scale, with the kind of transparency, stability and efficiency that modern pipeline and energy projects expect.

Project-Ready Supply: What Octal Controls Beyond the Steel Silo Structure

Octal positions its China steel silo scope as an acceptance-ready supply package, not just fabricated steel. Steel silo structures, silo system modules, and related liquid tanks can be released under one boundary with interface lists that match how EPC and plant teams review equipment. Each shipment is organized so receiving can be closed by item and lot: packing lists map to equipment IDs, and marking/protection is applied for key interfaces to reduce site damage and “missing identity” NCRs. For system packages, Octal aligns transfer and dust-control equipment (dust collector, conveying/lifting, discharge/pneumatic interfaces, valves, and packaging/export modules) to the defined throughput and material behavior so the silo does not become a standalone bottleneck. Configuration is built around project inputs—capacity, diameter, material flow-ability/abrasion, enclosure and dust targets (including fly ash compliance cases), automation scope, and packaging mode—so the delivered scope matches the specification rather than requiring rework after arrival. After delivery, Octal supports spare parts and interface troubleshooting to keep commissioning and ongoing operation stable.
