-
4. **Precision machined threads**
NPT / BSPT / BSPP optional, thread tolerance complies with ISO7-1 / DIN2999 / ANSI B1.20.1 for leak-free assembly.
-
5. **150LB pressure class**
Compliant with ISO 4144 standard, suitable for general industrial piping service.
-
6. **Pickled & passivated surface**
Clean metallic finish, enhanced anti-corrosion property, body marking available.
-
7. **Full size range**
1/4″ ~ 4″ (DN8 ~ DN100), OEM marking supported.

Frequently Asked Questions
Find answers to common questions about sizing, materials, threaded connections and operating conditions.
1、What is 90° Street Elbow?
It is a 90-degree threaded elbow with **male thread on one end and female thread on the other end (M × F)**. It changes the flow direction at 90° and connects a female port to a male nipple directly.
Important distinction: Street elbow (M×F) is different from regular female elbow (F×F). They cannot be interchanged.
2、What thread standards are available?
We support NPT (ASME B1.20.1), BSPT (R/Rc, EN10226), BSPP (G, ISO228-1).
Threads are NOT interchangeable. Please confirm thread standard and size before placing order.
3、What stainless steel grades can you supply?
Standard grades:
– 304 / CF8 for water, air and general low-corrosion service
– 316 / 316L / CF8M for coastal, brine, chemical and chloride-containing media.
4、What standards and pressure rating?
Cast version follows ISO4144 / MSS SP-114, Class 150LB (PN16).
5、Manufacturing process: casting or bar stock machined?
Standard stock items: lost wax investment casting.
High-pressure, high-precision requirement: solid bar CNC machined, higher cost.
7、Can you provide MTC material certificate?
Yes, EN10204 3.1 MTC with heat number is available. EN10204 3.2 third-party certificate can be arranged at buyer’s extra cost.
8、Surface finish options?
Standard: pickled matte finish.
9、Can you do laser marking?
Yes. We can mark size, grade, heat number, customer logo or brand on the flats.
10、Packaging for sea shipment?
Male threads are protected by plastic thread caps. Packed into export cartons, then loaded on fumigated wooden pallets with waterproof stretch film to avoid scratch and thread damage.
11、What is the lead time?
Typically, shipments are dispatched within 7–15 days of receiving the deposit, depending on the order quantity.
12、How is quality controlled?
Raw material inspection → CNC machining → Thread inspection → Hydrostatic testing → Visual inspection → Final dimensional verification before packaging.
13、Which Incoterms are available for overseas buyers?
We offer FOB (Free On Board) terms, with the shipment originating from a Chinese port. We will provide a commercial invoice, packing list, and bill of lading for import customs clearance.
14、Which Incoterms are available for buyers?
We offer FOB (Free On Board) or CIF (Cost, Insurance, and Freight) terms, with shipments originating from a Chinese port. We will provide a commercial invoice, packing list, and bill of lading for customs clearance.
15、What should be done if the threads are found to be defective or do not meet requirements upon arrival?
Please provide photos, videos, and inspection records. We will assess the root cause; depending on the contractual terms, solutions may include product replacement, a partial refund, or a reshipment.”
