About Kalp Overseas - Steel Pipes Supplier in India

India‑based Kalp Overseas lists six active products covering steel pipe specifications and nickel‑based alloy pipe families. The catalogue groups the items under the top categories “Steel Pipes” and “Metal Alloys”, reflecting the supplier’s focus on pressure‑rated tubing for oil‑&‑gas, petrochemical and power‑generation applications. Each entry references internationally recognised standards such as API 5L, ASTM A335, A106 and duplex stainless steel grades, and two items include explicit HS codes (7304.23 for duplex steel pipe and 7506.20 for nickel alloy pipe). The supplier’s tier is listed as imported with a harbor trust rating, indicating that it operates through Indian export channels rather than as a domestic manufacturer.

Product Range and Specialties of Kalp Overseas

The product list contains three API‑based carbon steel pipe families - A335 P91/P9/P22/P5, API 5L X60/X52 PSL‑2 and A106 GR.C/GR.B - as well as a broader steel pipe grouping that mentions standards A333, A335, API 5L, A106, A312 and A790. In the alloy segment the catalogue specifies duplex stainless steel UNS S31803 / S32205 (22 % Cr, 5 % Ni, 3 % Mo, N) and nickel alloys such as Inconel 625, Incoloy 800H, Hastelloy C276 and Monel 400. In the industry these grades are typically supplied in seamless or welded forms, with diameters from 2 mm to 1 200 mm, wall thicknesses defined by schedule numbers, and pressure ratings up to 250 bar for high‑alloy grades. Buyers often request compliance with API 5L (product specification), ASTM A335 (temperature rating) and ASTM A790 (duplex) together with mill test reports that detail chemical composition, tensile strength and impact values.

Trade and Export Information - Kalp Overseas

India is a major exporter of carbon‑steel and alloy pipes, with shipments frequently destined for the Middle East, Africa, Southeast Asia and Latin America where oil‑field and power‑plant projects dominate demand. The HS‑code family 7304 covers steel pipes, tubes and hollow profiles, while 7506 applies to nickel‑based alloy products; customs authorities in importing countries commonly require certificate of origin, material safety data sheets and conformity to the relevant API or ASTM standards. Typical trade terms include FOB Indian ports (e.g., Mumbai or Nhava Sheva) and CIF to regional hubs, with containerised loads of 20 ft or 40 ft depending on pipe dimensions, or bulk shipments for large‑diameter sections. Exporters from India often hold ISO 9001 quality‑management systems, but buyers should verify specific API product certifications and any required third‑party inspection (e.g., SGS, Bureau Veritas).

Sourcing from Kalp Overseas - Buyer Guidance

When sourcing from Kalp Overseas, buyers should request a full mill test report (MTR) for each pipe grade, confirming chemical analysis, tensile strength, hardness and impact energy at the specified temperature. For API‑specified pipes, the seller should provide the API product specification sheet and evidence of compliance such as a third‑party inspection certificate or API‑Q1 audit report. Verification of the HS code, material grade (e.g., UNS S32205 duplex or Inconel 625) and dimensional tolerances should be cross‑checked against the purchase order before shipment, and a pre‑shipment inspection can reduce the risk of non‑conformity.

What standards do the steel pipe products from Kalp Overseas follow?

The listed steel pipes reference API 5L, ASTM A335, ASTM A106, ASTM A333 and ASTM A312 specifications, covering seamless and welded grades for pressure service up to 250 bar.

Which HS codes are associated with the duplex stainless and nickel‑alloy pipes?

Duplex stainless steel pipes are classified under HS 7304.23, while the nickel‑based alloy pipes (Inconel, Incoloy, Hastelloy, Monel) fall under HS 7506.20.

What material grades are offered for the alloy pipe category?

The alloy catalog includes duplex stainless steel UNS S31803 / S32205 (22 % Cr, 5 % Ni, 3 % Mo, N) and nickel alloys such as Inconel 625, Incoloy 800H, Hastelloy C276 and Monel 400.

What documentation should a buyer request before purchasing?

Buyers should ask for a mill test report, API product specification sheet, certificate of origin and, where required, a third‑party inspection certificate confirming compliance with the relevant ASTM or API standards.

Are there typical minimum order quantities or lead times for these pipes?

Lead times depend on pipe size and grade but generally range from 4 to 8 weeks after order confirmation; minimum order quantities are usually specified per diameter and schedule and are negotiated per shipment.

What packaging and shipping methods are used for the pipe products?

Pipes are commonly packed in wooden crates or steel‑framed bundles, secured on 20 ft or 40 ft containers for ocean freight, with FOB Indian ports as the standard Incoterm.
