1. In terms of oil and gas transmission pipelines

Subsea oil and gas gathering and transportation pipelines: SSAW Steel Pipes can be used to connect short distance gathering and transportation pipelines between various offshore wellheads and production platforms. Due to its ability to adapt to certain pressure and flow requirements, it plays a role in oil and gas collection systems in shallow water areas. For example, in some small offshore oil and gas fields, the oil and gas produced by dispersed oil wells are collected through SSAW steel pipes to a central processing platform. The characteristics of its spiral welds enable the pipeline to have good flexibility to disperse stress and reduce the risk of pipeline damage when subjected to uneven external forces caused by complex seabed terrain.

Internal transportation pipeline of the platform: used within offshore oil and gas extraction platforms to transport preliminarily processed oil and gas to subsequent refined processing units or storage units. Due to the limited internal space of the platform, there are certain requirements for the flexibility of pipeline layout. SSAW steel pipes can be bent and installed according to the structure and equipment layout of the platform, while ensuring the efficiency and safety of oil and gas transportation. For example, the pipeline between the oil and gas separation device and the gas compression equipment on the platform can meet the requirements of medium transportation by using SSAW steel pipes, and its relatively low cost also has certain advantages.

2. In terms of platform structure support

Auxiliary support structure: SSAW steel pipes can be used as structural materials in some secondary structural support parts of offshore platforms, such as handrails, railings, small piers, and other non critical load-bearing parts on the platform. Its strength can meet the basic requirements for personnel passage and equipment placement, and due to the presence of spiral welds, the stress distribution on the welds is relatively reasonable when processed into various shapes (such as bent into armrest shapes), reducing the possibility of structural damage caused by stress concentration.

Temporary facility structure: SSAW steel pipes can provide temporary structural support for some temporary facilities during the construction process of offshore platforms, such as construction platforms, material stacking racks, etc. Its high production efficiency can meet the rapid supply demand for materials during the construction process, and its performance can meet short-term load-bearing and protective requirements in temporary use scenarios.

3. In terms of water and gas injection system pipelines

Water injection pipeline: SSAW steel pipes can be used to make water injection pipelines when conducting water injection operations in offshore oil and gas fields to improve recovery. Due to the relatively low pressure requirements on pipelines during the injection process of seawater or treated water (compared to oil and gas transportation), SSAW steel pipes can withstand the pressure of the water injection system, and their corrosion resistance can meet the transportation requirements of seawater or water containing certain minerals through appropriate anti-corrosion measures (such as internal coating).

Gas injection pipeline (low-pressure section): In some low-pressure gas injection systems, such as those used for oil reservoir displacement, SSAW steel pipes can be used as gas injection pipelines if the gas pressure is low. It can transport gas from the compressor or storage tank to the injection point near the wellhead, providing additional energy to the oil reservoir and improving oil and gas extraction efficiency.

4. In terms of fire protection and utility pipelines

Fire water pipeline: SSAW steel pipes can be used as fire water pipelines in the fire protection system of offshore platforms. The pressure of fire water in the pipeline is relatively stable, and the main requirement for water quality is to ensure that there are no impurities blocking the nozzles. SSAW steel pipes can meet the transportation requirements of fire water, and in emergency situations such as fires, their good mechanical properties can ensure that they will not easily rupture under certain external impacts (such as collisions with fire equipment), ensuring the normal supply of fire water.

Public utility pipelines (such as seawater cooling pipelines): For some equipment on offshore platforms (such as power generation equipment, air conditioning equipment, etc.) that requires seawater cooling, SSAW steel pipes can be used to make seawater cooling pipelines. Its resistance to seawater corrosion and sufficient strength can ensure the long-term stable operation of the cooling system, transporting seawater from the intake to various equipment that needs cooling, and then discharging the heated seawater back into the sea.

5. Application of wastewater treatment system pipelines

Oil containing wastewater transportation pipeline: SSAW steel pipes can be used to transport oil containing wastewater in the wastewater treatment process of offshore platforms. The oily wastewater collected from various production stages of the platform contains petroleum substances and other impurities, and is transported to the oil-water separation device through SSAW steel pipes. Due to the ability of SSAW steel pipes to withstand certain internal pressures and corrosive environments, and to be flexibly laid according to actual layout requirements, it helps ensure the effective collection and transportation of oily wastewater, preventing leakage and pollution of the marine environment.

Wastewater discharge pipeline after treatment: The treated standard wastewater needs to be discharged into the sea, and SSAW steel pipes can be used as discharge pipelines. Its good sealing and corrosion resistance can ensure the safe and compliant discharge of wastewater, while its mechanical properties can resist the impact of water flow and external pressure in the marine environment, and complete the wastewater discharge task stably for a long time.

6. Application of chemical transportation pipelines (with certain limitations)

Low corrosion chemical transportation: For the transportation of some low corrosion chemicals (such as some water treatment agents, anti scaling agents, etc.) used in offshore platform operations, SSAW steel pipes can be used as transportation pipelines under the premise of meeting pressure and safety requirements. By appropriate internal coating treatment or material selection, the pipeline's resistance to these chemicals can be enhanced, ensuring the safe delivery of chemicals to the point of use. However, for highly corrosive chemicals such as strong acids and alkalis, more corrosion-resistant pipes or special protective measures are usually required.

7. Application of communication and instrument cable protection conduit

Cable protection conduit: Communication and instrument cables are key facilities to ensure the normal operation of offshore oil and gas extraction platforms. SSAW steel pipes can be used as cable protection pipes to wrap cables inside, preventing them from being subjected to mechanical damage, seawater erosion, and electromagnetic interference. Its spiral structure can provide a certain degree of flexibility, making it easy to lay in complex platform structures, and the strength of the steel pipe can resist the collision and compression of external objects, ensuring the safety of the cable.

8. Application of mud and drill cuttings transportation pipelines (during the drilling phase)

Mud transportation pipeline: During the drilling operation phase on offshore platforms, drilling mud needs to be transported through pipelines. SSAW steel pipes can be used for mud transportation pipelines from the mud preparation area to the wellhead. Drilling mud has a certain density and pressure, and SSAW steel pipes can withstand these pressures and ensure stable transportation of mud, providing necessary support for drilling operations such as cooling drill bits and carrying drilling cuttings.

Drill cuttings transportation pipeline: The drill cuttings generated during the drilling process need to be transported to specialized processing areas or storage facilities, and SSAW steel pipes can be used as drill cuttings transportation pipelines. Its smooth coating (if any) or suitable inner diameter can reduce the risk of blockage during the transportation of drill cuttings, while its strength can withstand the weight of drill cuttings and the pressure generated by flow, ensuring effective handling of drill cuttings and cleaning of the platform.
