Welspun Corp shares rose as much as 9% after the company secured its largest-ever order, valued at $1.8 billion, or about Rs 17,200 crore, for pipe supplies from its US manufacturing facility.

The order has lifted Welspun Corp's global order book to a record $4.4 billion, or about Rs 42,100 crore. The company said the win improves multi-year revenue visibility and strengthens its position in global energy infrastructure.

Welspun Corp, the flagship pipes company of the Welspun Group, is one of the world's largest manufacturers of large-diameter steel pipes used in oil, gas and water transmission pipelines. It runs manufacturing plants in India as well as overseas, including its US unit Welspun Tubular in Little Rock, Arkansas, which supplies line pipes to customers across North America. That overseas footprint allows the company to bid for large energy pipeline projects outside India.

Welspun Corp share price: Welspun Corp shares rallied sharply after the announcement of the contract, which marks the company's biggest order to date. The latest award adds to its pipeline of business and expands its order book to a new high on a global basis.

The stock was one of several pipe and tube names in focus, alongside APL Apollo Tubes, Jindal Saw, Ratnamani Metals & Tubes, and Man Industries (India). These companies span different niches of the sector — APL Apollo is a leading producer of structural steel tubes used in construction, while Jindal Saw, Ratnamani Metals and Man Industries primarily serve energy and water pipeline demand — and order flows across the industry are driven by pipeline project spending by oil, gas and utility customers.

Welspun Corp's US manufacturing facility will supply the pipes under the new order. The company's updated order book of $4.4 billion underscores the scale of its current project pipeline and extends visibility for future execution.
