How can we
help you?

We supply pipes and tubes, butt-weld and forged fittings, flanges, olets, plates, sheets, coils, bars, structural sections, fasteners, gaskets, fin tubes, pipe spools and drawing-based fabricated components.

Our range covers stainless, carbon and alloy steels; duplex and super duplex; nickel alloys including Inconel, Monel and Hastelloy; plus copper, brass, aluminium and other non-ferrous materials. Availability must be confirmed against the exact product form and specification.

Yes. Steel Gems supports drawing-based fittings, flanges, pipe spools, machined components and custom fabrication. Send the approved drawing, material, quantity, tolerances, inspection requirements and delivery location for review.

No. Catalogue ranges show our supply capability and technical coverage. Stock, mill availability, quantity and lead time must be reconfirmed when requesting a quotation.

Seamless pipe has no longitudinal weld. ERW uses electrical resistance at the seam, EFW uses fusion welding, and SAW uses submerged-arc welding—commonly in larger diameters and heavier sections. Suitability depends on the governing specification and service.

Schedule identifies a wall-thickness series; it is not itself a thickness. The actual wall corresponding to a schedule changes with nominal pipe size. Always state the NPS/NB, schedule and dimensional standard.

No. Flange class is a pressure-temperature rating designation. Allowable pressure depends on flange material and operating temperature. PN is a separate rating system and is not automatically dimensionally interchangeable.

Only after technical comparison and purchaser approval. Similar chemistry or strength does not automatically make grades interchangeable; product standard, heat treatment, testing, dimensions and service conditions must be checked.

EN 10204 3.1 documentation is commonly available subject to the offered material. A 3.2 requirement needs advance confirmation because purchaser or designated third-party validation and witnessing may be involved.

Yes. We can coordinate inspection requirements involving agencies such as BV, TUV, DNV or Lloyd, subject to the approved QAP/ITP, scope, availability and applicable charges.

Depending on the product and specification, support can include PMI, UT, RT, DPT/PT, MPI, hydro, IGC, hardness, chemical and mechanical testing, including NABL laboratory coordination.

Yes, where specified and agreed. Material identification and records can be maintained through cutting, machining and fabrication. State the marking and traceability requirement clearly in the RFQ.

Use the RFQ builder or WhatsApp button and send product, grade, size, standard, quantity and delivery location. Steel and alloy prices can change, so pricing and availability are confirmed against the enquiry date.

Yes. Steel Gems supports Pan-India dispatch and export enquiries. Freight, packing, taxes, delivery basis and documentation are confirmed separately in the quotation.

Payment terms depend on the customer, material, manufacturing scope and order value. They may include advance payment, staged payment or approved credit terms. The written quotation and purchase order confirmation govern each transaction.

Provide product name, material grade, product specification, dimensions, schedule/class/facing or end type, quantity, testing and documentation, delivery location and required date. Attach drawings or project specifications when applicable.

Calculator outputs are theoretical estimates based on nominal dimensions and density. Actual weight can vary because of tolerances, machining, coating and manufacturing variation. Use certified product data for final commercial or engineering decisions.
