Seamless and welded carbon steel pipe supplied for industrial piping, oil & gas, water, construction and infrastructure projects. ASTM, API 5L and project-specific specifications available for bulk orders.
JS FITTINGS supplies seamless, ERW, LSAW and SSAW steel pipe for overseas stockists, distributors, trading companies, EPC contractors and industrial project buyers. The website currently lists bulk supply, standard and customized steel pipes, quality inspection and global service as core supply capabilities.
Common specifications include ASTM A106, ASTM A53, ASTM A333 and API 5L. Suitable for pressure piping, oil & gas, refinery, petrochemical, power and industrial applications.
ERW steel pipe for industrial piping, water, gas, structural and project applications. Common specifications include ASTM A53 and API 5L.
Large OD welded pipe for oil & gas, natural gas, water transmission and infrastructure projects. API 5L grades including Gr.B, X42, X52, X60 and X70 can be supplied according to requirements.
Large diameter spiral welded carbon steel pipe for water, oil, gas, infrastructure and other industrial pipeline applications.
Schedule is one of the first specifications industrial buyers need to confirm. JS FITTINGS supplies SCH 40, SCH 80 and SCH 160 carbon steel pipe for different industrial and project requirements.
For the same nominal pipe size, schedule changes wall thickness and therefore affects weight, internal diameter and material consumption. The correct schedule should always follow the project specification and design requirements.
Send the complete specification when requesting a quotation. This allows our team to check the manufacturing route, available size range, testing requirements and delivery arrangement.

Specify the pipe end and surface condition together with grade, size and quantity to avoid unnecessary quotation changes during procurement.
Bevelled ends are commonly specified for welding applications. The bevel geometry and end preparation should follow the applicable project or pipe specification.
Plain-end carbon steel pipe is available for applications where no bevel preparation is required or where further end processing will be completed by the buyer.
Oiled or anti-rust oil surface protection can be used to reduce corrosion during storage and international transportation.
Depending on the application, protective options include FBE, 3PE/3LPE, epoxy, varnish and other specified surface treatments.
Quality control is especially important when carbon steel pipe is purchased for stock inventory or engineering projects. JS FITTINGS states that both its internal quality inspection department and third-party inspection are available.
Confirm standard, grade, OD, wall thickness, length, ends and quantity before production.
Review material requirements and applicable technical specifications.
Check dimensions, appearance and required production parameters.
Testing can include mechanical, dimensional, hydrostatic and NDT requirements according to specification.
Buyer or third-party inspection can be arranged before final loading and shipment.
JS FITTINGS publishes ISO 9001 system certification together with API 5L, CE and ASTM/EN standards information. The company also lists GOST-R, PETROBRAS, ADNOC and NIOC among its certifications and approvals.
Additional approval and certification documents can be reviewed according to the product and project requirements.
Real project experience is particularly important for buyers evaluating a supplier for bulk or repeat orders.
JS FITTINGS supplied 6 containers of large-diameter API 5L LSAW steel line pipe to a Nigerian customer for a natural gas project.
JS FITTINGS also presents API 5L seamless pipe supply covering Grade B through X70, PSL1 and PSL2, with coating options including 3LPE and FBE.
For buyers sourcing multiple pipe specifications from one supplier, additional standards can be discussed according to material, application and project requirements.
Stainless steel pipe specification for applications requiring stainless material. Available according to project requirements.
Stainless steel alloy-steel boiler, superheater and heat-exchanger tube specification for applicable projects.
Stainless steel tubing specification commonly used for general corrosion-resisting service.
For industrial procurement, the applicable material specification should always be confirmed together with grade, dimensions and service conditions.
Common grades include ASTM A106 Gr.B, ASTM A53 Gr.B, ASTM A333 Gr.6 and API 5L Gr.B, X42, X52, X60, X65 and X70, subject to the applicable product and project requirements.
