Straight Pipe Thread Fittings

Straight pipe thread fittings are used to connect two pipe sections in a straight line through internal threads, external threads, or a combination of both. The threaded structure provides a detachable connection and is commonly used where welding is not required.

Nominal sizes generally range from 1/8 inch to 4 inches, with some product series extending to 6 inches. Available thread forms can include NPT, BSPT, and BSPP, depending on the specific product and purchasing requirements.

Body materials can include carbon steel, stainless steel, malleable iron, and brass. Common pressure classifications include PN10, PN16, and Class 150, but the applicable rating should always be confirmed according to the actual product series rather than applying one rating to all sizes and configurations.

Surface options can include galvanizing, hot-dip galvanizing, and natural stainless steel.

For this product category, matching the thread standard is one of the most important steps before ordering.

Two fittings may have similar nominal sizes but still be incompatible if one piping system uses NPT and another uses BSPT or BSPP. Buyers should therefore confirm the nominal size, male or female thread arrangement, thread standard, material, and surface treatment before placing a bulk order.

Straight pipe thread fittings can be used in water supply and drainage systems, fire protection piping, HVAC installations, compressed air systems, machinery, industrial fluid systems, pump and valve connections, and general process piping.

The detachable threaded connection also makes the product suitable for installation points where future maintenance or component replacement may be required.

Zhuori Metal has metal processing and hardware product manufacturing capabilities and can confirm fitting specifications according to customer technical drawings, samples, and connection requirements.

For customized straight pipe thread fittings, production can be arranged around nominal size, body material, thread type, and required surface treatment.

The company's internal workflow covers raw material purchasing, processing, inspection, and packing. Production and quality inspection personnel follow the confirmed order specifications when checking dimensions and product structure.

For equipment manufacturers or buyers with recurring requirements, the first confirmed sample and specification can be used as the reference for later repeat orders.

Samples are available before mass production, and custom sample development normally takes about one week. Small sample quantities can be supplied.

OEM and ODM services are supported, and several dimensions or fitting models can be included in one purchase order.

A 100% inspection is completed before packing, while third-party inspection is accepted. Photo or video manufacturing updates can also be provided.

Standard products generally require about 15 days for production, while customized products normally require around one month. Repeat-order lead times may be shorter when previously confirmed specifications are available.

This process helps buyers reduce specification risk when purchasing product for installation, equipment production, or maintenance stock.
