THX SPECIAL STEEL supplies Plastic-steel-pipe (Liner Pipe) for steel-plastic composite lined pipe that combines the pressure-bearing strength of seamless steel with a thermoplastic inner liner for corrosion, scale and wear control. Materials can be matched to project and petrochemical lining requirements, with the website referencing Q/SH1020 1889-2020 for UHMWPE lined steel compounded tubing, while stock and non-standard processing help customers source products around real project conditions rather than only standard mill sizes. The company supports export-oriented orders that combine material supply, processing, inspection and shipment in one workflow.
The category covers UHMWPE lined tubing, HDPE inserted liner pipe and other steel-outer/plastic-inner composite pipe structures. This range allows buyers to consolidate related grades and dimensions through one supplier. THX SPECIAL STEEL maintains ready stock across several finished and semi-finished steel products, while project-specific dimensions or delivery conditions can be prepared when standard inventory does not match the requirement. This flexibility is useful for distributors, fabricators and end users handling mixed specifications or urgent replacement demand.
Typical applications include sour oil well production, water injection, oilfield tubing, corrosive fluid transfer and services where eccentric wear, scaling or chemical attack shortens steel-tube life. Material choice should consider the complete service environment because pressure, temperature, cyclic loading, corrosion, dimensional tolerance and downstream fabrication can change the most suitable grade. Providing the applicable standard, service medium, operating conditions and final component use before ordering helps reduce specification errors and unnecessary over-design.
Key selection factors include base steel pipe pressure rating, liner polymer, operating temperature, chemical medium, wear severity, internal diameter after lining and connection method. THX SPECIAL STEEL can arrange liner extrusion, diameter reduction and insertion, stress relief, sizing and flanging are key steps described for the UHMWPE composite process. These services can reduce local preparation work by supplying material closer to the required production condition. For repeat orders, agreed dimensions, heat-treatment condition and inspection scope also help improve consistency between batches.
Relevant quality checks can include liner adhesion, dimensional fit, wear resistance, chemical compatibility and base-pipe integrity must be checked as a combined system. The website also highlights standardized internal quality control and third-party inspection support from SGS, TUV and DNV. Traceable documentation is particularly important for energy, pressure-bearing, low-temperature and other critical applications, so required certificates and test items should be confirmed before shipment.
The site's UHMWPE product information highlights strong wear, chemical and impact resistance and reports an oilfield case where lined tubing substantially extended the pump inspection cycle, illustrating the category's role in reducing workovers. THX SPECIAL STEEL also supports professional packaging and international sea, rail and multimodal logistics. For a more accurate quotation, buyers can provide the grade, standard, dimensions, quantity, application, delivery condition and required inspection documents. This helps the team match stock, processing and delivery arrangements to the actual project.
Before placing an order for Plastic-steel-pipe (Liner Pipe), confirm the material grade or equivalent standard, exact dimensions, quantity, end-use environment, heat-treatment or surface condition, tolerance, inspection level and packaging requirements. If the grade is not fixed, sharing the application and working conditions allows THX SPECIAL STEEL to review suitable material options and processing routes before quotation.
