Pipes and tubes manufacturer, supplier and exporter serving Indonesia
Kalp Alloys manufactures seamless pipes, welded pipes, ERW and EFW tubes, flanges, buttweld fittings, forged fittings, instrumentation fittings, valves, sheets and plates, round bars and wire rods, fasteners, wire mesh and fabricated piping spools at its own works in Ahmedabad, Gujarat, India, and exports them to EPC contractors, plant builders, fabricators, stockists, distributors and end users across Indonesia. We are the producing mill and not a trading layer, so the enquiry, the material, the mill test certificate and the delivery commitment all sit with one accountable party.
Buyers in Indonesia order from us in stainless steel, carbon steel, alloy steel, duplex and super duplex, nickel alloys such as Inconel, Incoloy, Hastelloy and Monel, copper alloys, titanium and aluminium. Scope runs from a single made-to-drawing flange against a shutdown to a full project package released in phases against a construction programme. Where the drawing is unclear on a brownfield tie-in, send the measured bolt circle, bolt count and raised-face dimension and we will confirm the matching standard before quoting.
Every consignment leaving for Indonesia is inspected before packing and shipped with an EN 10204 3.1 mill test certificate as the floor, chemical and mechanical results, heat number traceability and a dimensional report. EN 10204 3.2 with a third-party inspector from SGS, BV, TUV or Lloyds is arranged at our Ahmedabad plant where the specification calls for it, along with NDT records, hydrostatic test reports, PMI results and a NACE MR0175 statement on sour service.
Consignments route mundra to Tanjung Priok at Jakarta, Tanjung Perak at Surabaya and Belawan, with a sea transit of 12 to 18 days port to port, with Singapore transhipment on many services. Stock sizes release in three to seven days, made-to-drawing items are quoted with a firm lead time, and air freight is priced separately when material is needed against a shutdown window. FOB, CFR, CIF and DAP are all quoted so landed cost in Indonesia can be compared properly rather than against an ex-works price.
Pipes, Tubes and Piping Material We Manufacture and Export to Indonesia
Kalp Alloys supplies the complete piping package to Indonesia from a single works: seamless and welded pipes and tubes, flanges, buttweld fittings, forged fittings, instrumentation fittings, valves, sheets and plates, round bars and wire rods, fasteners, wire mesh and fabricated piping spools. Every item below is manufactured, inspected and certified in Ahmedabad, India and shipped with an EN 10204 3.1 or 3.2 mill test certificate issued in our own name.
73 product variants across 11 categories are quoted for Indonesia, in stainless steel, carbon steel, alloy steel, duplex and super duplex, nickel alloys, copper alloys, titanium and aluminium.
Pipes and tubes go out as seamless, welded, ERW and EFW in round, square and rectangular section. Flanges cover weld neck, slip on, blind, socket weld, lap joint, threaded, spectacle blind, orifice and long weld neck in raised face, flat face and ring type joint. Fittings cover elbows, tees, reducers, caps, stub ends, crosses, couplings, unions, plugs, bushings and nipples. Anything in the list can be quoted individually or as a matched package for a single line, so a buyer in Indonesia does not have to split one bill of material across four suppliers.
Material Grades Supplied to Indonesia
Grade selection follows the service, not the catalogue. These are the families quoted routinely for Indonesia; anything outside them is quoted against the specification.
Where the line is clean and the temperature moderate, carbon steel to ASTM A105 or A106 Gr B is the economic answer and there is no case for paying an alloy premium. Chloride, seawater or a sour stream moves the choice to duplex, super duplex or a nickel alloy, and high-temperature steam moves it to F11, F22 or F91. Send the medium, the design temperature and the design pressure with the enquiry and the grade recommendation comes back with the quotation rather than after it.
| Material family | Grades commonly supplied | Typical application |
|---|---|---|
| Stainless Steel | ASTM A182 F304, F304L, F316, F316L, F316Ti, F317L, F321, F347, 904L | Chemical, pharmaceutical, food, water treatment |
| Carbon Steel | ASTM A105, A350 LF2, A106 Gr B, A53, API 5L X42 to X70 | Oil and gas, power, structural and utility piping |
| Alloy Steel | F5, F9, F11, F22, F91, P11, P22, P91 | High-temperature steam, refinery and boiler service |
| Duplex & Super Duplex | UNS S31803, S32205, S32750, S32760, F51, F53, F55 | Offshore, desalination and seawater handling |
| Nickel Alloys | Inconel 600, 601, 625, 718; Incoloy 800, 825; Hastelloy C22, C276; Monel 400, K500 | Aggressively corrosive and high-temperature process |
| Copper Alloys | Cu-Ni 90/10, Cu-Ni 70/30, brass, bronze, aluminium bronze | Seawater cooling, HVAC and condenser circuits |
| Titanium | Grade 1, Grade 2, Grade 5, Grade 7 | Desalination, chemical and aerospace service |
| Aluminium | 6061, 6063, 5083, 2024 | Lightweight structural and heat-transfer work |
Size Range and Supply Scope for Indonesia
Standard size envelope quoted to Indonesia. Made-to-drawing and non-standard items are produced against the drawing with a firm lead time.
Large-bore flanges above 24 inch are supplied to ASME B16.47 Series A and Series B, and metric scope is supplied to EN 1092-1 PN ratings or to DIN and BS references where the plant was built to them. Odd sizes, obsolete ratings and non-catalogue face types are forged to drawing, which is normally the only route on a brownfield tie-in in Indonesia where the existing counter-flange no longer matches a current standard.
| Product | Size range | Types and ratings |
|---|---|---|
| Pipes & Tubes | 1/8" NB to 48" NB | SCH 5S to XXS; seamless, welded, ERW and EFW |
| Flanges | 1/2" to 60" | Class 150 to 2500, PN6 to PN100; WNRF, SORF, BLRF, SWRF, LJ, threaded, RTJ |
| Buttweld Fittings | 1/2" to 48" | SCH 10S to XXS; elbow, tee, reducer, cap, stub end |
| Forged Fittings | 1/8" to 4" | 2000, 3000, 6000 and 9000 LBS; socket weld, threaded NPT and BSP |
| Sheets & Plates | 0.5 mm to 120 mm thick | Hot rolled, cold rolled, 2B, No.4, BA and mirror finish |
| Round Bars & Wire Rods | 4 mm to 500 mm diameter | Bright, black, peeled, centreless ground and forged |
| Fasteners | M2 to M64 and 1/4" to 4" | Stud bolts, hex bolts, nuts, washers and anchor fasteners |
Which standards apply in Indonesia
ASME B16.5 and B16.47 with API specifications govern hydrocarbon scope, SNI references apply on domestic and utility work, and JIS appears on Japanese-built plant.
Getting this right at enquiry stage avoids the most expensive mistake in export piping supply: material that is correct to one standard and unusable against the project specification. State the governing standard and the class or PN rating on the enquiry, and the quotation is built against it rather than against an assumption.
Shipping route and transit time to Indonesia
Consignments route Mundra to Tanjung Priok at Jakarta, Tanjung Perak at Surabaya and Belawan. 12 to 18 days port to port, with Singapore transhipment on many services.
Production lead time runs ahead of that. Stock sizes are released in three to seven days and made-to-drawing items are quoted with a firm lead time, so a realistic door-to-door figure is production plus transit plus clearance. Air freight is quoted separately where material is needed against a shutdown window.
Packing is seaworthy as standard: material is strapped and bundled, wooden cases are heat-treated and ISPM-15 marked where required, and each package is marked with the heat number so it can be matched to its certificate on arrival. The full sequence is set out on the export process page.

Documentation and approvals for Indonesia
Buyers in this market normally require pertamina and operating company vendor documentation, SNI conformity where a mandatory standard applies, EN 10204 3.1 or 3.2, and NACE MR0175 on sour gas.
The standard pack issued with every consignment is the EN 10204 3.1 mill test certificate with chemical and mechanical results and heat number traceability, the dimensional inspection report, and the packing list matched to the certificate. EN 10204 3.2 with an independent inspector, NDT records, hydrostatic test reports, PMI results and a NACE MR0175 compliance statement are added where the specification calls for them.
Export documents — commercial invoice, packing list, certificate of origin, bill of lading and any market-specific attestation — are prepared with the shipment rather than after it.
Testing and quality control before a shipment leaves for Indonesia
Nothing is packed for Indonesia until it has been through the in-house inspection sequence. Raw material is checked against the heat certificate on receipt, the forging and heat treatment cycle is recorded against the heat number, and the finished part is measured before it reaches the packing bay.
Chemical analysis is run on a spectrometer, mechanical testing covers tensile, yield, elongation and hardness, and impact testing to the required temperature is added on low-temperature scope. Positive material identification confirms the alloy on stainless, duplex and nickel items, intergranular corrosion testing to ASTM A262 is run on austenitic stainless where the specification calls for it, and ferrite count is reported on duplex and super duplex.
Non-destructive testing covers ultrasonic, radiographic, dye penetrant and magnetic particle examination, and hydrostatic testing is carried out on valves and on fabricated spools. Dimensional inspection is checked against the governing standard or the approved drawing, and the report goes into the document pack that travels with the consignment to Indonesia.
How to order and what terms apply for buyers in Indonesia
Send the grade, the standard, the size and schedule or class, the face type, the quantity and the required delivery date. A drawing or a photograph of the existing part removes most of the back and forth on a replacement item. Quotations for Indonesia are issued typically within 24 hours, and include the unit price, the incoterm, the lead time and the certification level so nothing is discovered at invoice stage.
Payment is normally against an irrevocable letter of credit at sight or an advance and balance arrangement against shipping documents, and terms are agreed before production starts rather than after. Partial shipment is arranged where a construction programme needs early items released ahead of the balance.
Communication runs by email, phone and WhatsApp with one point of contact for the order, so a query about a heat number or a delivery date on a consignment bound for Indonesia is answered by the people who made and shipped the part.
Industries and project types we supply in Indonesia
Demand here concentrates on pertamina refinery upgrades, LNG and gas processing, mining and smelter process circuits, geothermal power, and palm oil and petrochemical plant.
Indonesia has three standards regimes bolted together: ASME on international scope, JIS on the substantial Japanese-built installed base, and SNI on domestic utility work. On brownfield work the governing question is what the counter-flange is, not what the specification says, so send the measured bolt circle and bolt count where the drawing is unclear.
Why buy direct from the Indian manufacturer
Most search results for pipe, flange and fitting supply resolve to marketplaces and stockist directories. They aggregate: the material is produced by an unnamed mill and the certificate that reaches the buyer is a copy passed along the chain. Kalp Alloys forges, machines and inspects at its own facility at 5, Jay Vijay Industrial Estate, B/h. Akash Vikas Estate, Keval Kanta Road, Rakhial, Ahmedabad, and issues the EN 10204 mill test certificate in its own name.
For a buyer in Indonesia that means one accountable party for the grade, the heat number, the dimensional report and the delivery date — and a technical answer that comes from the people who made the part.
For an importing buyer the practical consequence is margin and accountability. A trading layer adds a percentage without adding a capability, and when a certificate is queried it has to go back down the chain to whoever actually made the part. Buying at the mill removes both problems.
Frequently Asked Questions
Kalp Alloys manufactures seamless and welded pipes and tubes, flanges, fittings, valves, sheets, bars and fasteners in Ahmedabad, India and exports them to Indonesia.
