The SSAW line in brief
SSAW steel pipe is one of the six lines named on the company About page under its main products range. The letters SSAW stand for spiral submerged arc welding, which is the forming route that gives the line its name: the pipe is formed in a spiral and welded by a submerged arc route. That description names the route only. It does not state any wall thickness, material grade, execution standard or length for any pipe in the line. This page states none of them.
The company About page lists SSAW steel pipe with the size range OD 8 to 120 inch (219.1 to 3048 mm). That range is reproduced here as the About page lists it, and it should be read as a starting point for an enquiry rather than as a guarantee that every size inside the range is available for any particular order. A buyer who needs a particular size should name it in the first message, together with the application and the quantities, and ask for availability, quantity terms and timing to be confirmed for that size.
Where SSAW pipe is discussed
SSAW pipe is discussed on this site through the application directions named on the company About page: petroleum and gas pipelines, water pipelines, construction and building, dredging projects and piling projects. The application pages describe each direction and the lines discussed for it, and the SSAW page links to them so that a buyer can move from the line to the job and back again. No application page turns a direction into a promise about any particular order, and quantities, timing and terms for a job in any direction are settled in the enquiry.
Within those directions, SSAW pipe is most often raised where a spiral welded route is wanted for pipeline and structural work, including the piling and structure column names that appear under this line on the company homepage. Those column names are discussed on the structure pipe guide and the piling application page, and they are not turned into separate product lines on this site. A buyer whose job depends on a particular column name should name it in the enquiry, together with the line and the application, so that the answer can be tied to the job as described.
SSAW against the other welded lines
The three welded lines on this site, ERW, SSAW and LSAW, share the fact that they are welded, and differ in the welding route that forms them. SSAW pipe is formed in a spiral by a submerged arc route, ERW pipe by electric resistance welding along its length, and LSAW pipe by a longitudinal submerged arc route. The comparison page on ERW against SSAW sets the first two routes side by side on the basis of forming route and application direction, and the welded pipe guide covers all three together in the same terms. Neither page states a specification table for any line.
A buyer choosing between welded lines should start from the job rather than from the route name alone. A pipeline job, a water job, a piling job and a construction job can each raise different questions about length, handling and jointing, even when the same line name appears in more than one of them. The selection guide therefore asks the buyer to name the line, the application and the quantities together, and the enquiry checklist repeats that order. A buyer who follows it gives the supplier something concrete to answer, instead of a route name that still leaves the job undescribed.
Sizes, quantities and timing
The size range listed for this line is OD 8 to 120 inch (219.1 to 3048 mm), as given on the company About page. No wall thickness, length or grade is stated alongside it on this site, and no buyer should read the range as covering every combination of size and quantity. Where a size is wanted, the enquiry should name it, state the quantities, and ask for availability and timing to be confirmed for that size. Where quantities are not yet fixed, the enquiry should say so and ask what information the supplier needs before quantity terms can be discussed.
Timing and quantity terms depend on the items, the quantities and the destination, and they are settled in the enquiry rather than on this page. The same applies to trade terms, payment method and documents: this site uses only the general wording that certificates are available upon request, and any document question should name the items it concerns. A buyer who asks about all of those points together, for the same items, in the same message, will receive a reply that can be checked as a whole, which is the outcome the enquiry pages are written to support.
What to state in an SSAW enquiry
An SSAW enquiry should open with the line name, then name the application, then state the size wanted in outside diameter terms where a size is known, then state the quantities and the destination. Where a date exists by which the pipes are needed, it should state that date. Where the job touches a homepage column name, such as piling or structure work, it should name that column direction as well, so that the reply can cover the job as a whole. Those facts, line, application, size, quantities and destination, are the minimum that allows a direct answer, and the enquiry checklist page collects them in order.
An SSAW enquiry should also ask, in the same message, for quantity terms, timing, trade terms, payment method and documents to be confirmed for the items named. Splitting those questions across separate messages produces fragmented answers that are hard to check against the order, while gathering them produces a single reply that can be checked as a whole. That discipline is the same for every line on this site, and it is repeated on the line pages, the guide pages and the enquiry pages alike.
Certificates available upon request. Please confirm the minimum order quantity in your inquiry before placing an order. Please confirm the lead time with the supplier before placing an order. Please confirm the trade terms and payment method before confirming an order.
