Stainless Steel Thread Red Hex Nipple

Product Overview

The Stainless Steel Thread Class150 Cross is a robust 4-way pipe fitting designed for branching fluid flow in medium-pressure industrial systems. With a Class150 pressure rating, it safely handles water, oil, gas, and acidic media, making it essential for petroleum, chemical, construction, and environmental protection industries. Its investment-cast body and CNC-machined female thread ensure precise alignment and long-term durability, even in high-demand operations.

Detailed Product Specifications

Key Features & User Benefits

Reliable Pressure Endurance

The Class150 pressure rating ensures the fitting withstands medium-pressure conditions (common in petroleum pipelines and chemical reactors), preventing bursts and ensuring operational safety—critical for high-risk industries.

Efficient 4-Way Flow Branching

As a cross fitting, it enables 4-directional pipe connections without restricting flow. The female thread (machined to ISO standards) ensures tight seals, avoiding pressure drops and optimizing system efficiency.

Low-Carbon Material Options

Offering SS304L and SS316L (low-carbon stainless steel), the fitting resists intergranular corrosion—ideal for high-temperature or acidic environments like wastewater treatment plants and pharmaceutical facilities.

FAQ

What tools are used to test the fitting’s quality?

We use calipers/meter sticks (size), thickness meters (wall thickness), spectrometers (PMI tests), airtight equipment (leakage), and pressure tools (endurance).

Can we visit your factory before placing an order?

Yes, factory visits are welcome. We provide transparent access to production lines to build trust in our manufacturing processes.

Is this fitting suitable for outdoor construction projects?

Yes. SS304/SS316 materials resist outdoor weathering (rain, humidity), making it perfect for construction-site plumbing and gas pipelines.
